Handcrafted, high-tech interior
- Premium materials including genuine
aluminum and available carbon fiber trim
- More connected driving experience
through the smaller-diameter steering wheel and two new seat choices
- Advanced technologies including standard
dual, high-resolution information screens and available color head-up display.
The new Corvette Stingray interior blends fine materials and craftsmanship with
advanced technologies that contribute to a more connected and more engaging driving experience, said Helen Emsley, interior
“Every feature and detail in the interior is designed to enhance the driver’s
connection to the Corvette,” Emsley said. “It starts with the fighter jet inspired wraparound cockpit; continues
to build with the smaller steering wheel, more supportive seats, and high-definition, configurable screens, and is finished
in gorgeous materials.”
The smaller, 14.1-inch-diameter (360 mm) steering wheel fosters a more direct,
immediate feel to directional inputs. The attention to the driver extends to the smallest details, including the flat, precise
stitching on the steering wheel designed to provide a smooth, consistent feel.
Precise and elegant stitching also is seen in the available Napa leather trim
of the all-new seats.
Two seating choices will be offered: a GT seat for all-around comfort and a Competition
Sport seat with more aggressive side bolstering which provides greater support on the track.
The frame structure for both seats is made of magnesium for greater strength
and less weight than comparable steel frames. They’re also more rigid, contributing to the enhanced feeling of support
during performance driving.
Additional performance-enhancing details of the interior resulted from designers’
“field trips” to GM’s Proving Ground in Milford, Mich., where high-performance driving experiences spurred
the design and implementation of several features, including a steel-reinforced grab bar on the center console for the passenger
and soft-touch materials on the edge of the console, where the driver naturally braces during high-load cornering.
High-performance driving also influenced elements of the configurable display
screens and available head-up display, which vary depending on the driving mode, including the Track display inspired by the
The performance-supporting elements inside the new Corvette Stingray are complemented
by unprecedented attention to detail and build quality, including the sweeping arch motif over the driver cockpit trim and
the seamless transition of the line from the instrument panel to the door.
All models feature a fully-wrapped interior, where every surface is covered with
premium, soft-touch materials. Available materials, depending on the trim level, include Napa leather, aluminum, carbon fiber
A blend of hand craftsmanship and machined precision is intended to ensure the
fit, finish and ambience of the cabin is first-rate. The leather-wrapped instrument panel, for example, features hand-selected
and hand-stretched materials for better grain matching with stitching performed by robots that deliver perfect seams.
There’s even a micro-LED screen for the passenger’s climate control
placed below the vent on the on the dash away from the performance features on the instrument panel.
“To ensure the high quality of the interior, we spent time working on the
line alongside the team that builds the Corvette every day at Bowling Green Assembly Plant,” said Ryan Vaughan, interior
design manager. “And thanks to that collaboration between design, engineering and manufacturing, we were able to make
adjustments that allowed us to maintain the integrity of the design, improve the assembly process and ultimately deliver what
we believe to be a world-class interior.”
- Driver Mode Selector optimizes
12 vehicle attributes
- Configurable screens and head-up display can be tailored to the driver’s preference
- Central touch screen uses gesture-recognition
At the core of the Corvette Stingray’s driver-focused technologies is the
cockpit-mounted Driver Mode Selector, which allows drivers to optimize the car for their driving preference and road conditions
via five settings: Weather, Eco, Tour, Sport and Track.
“The all-new Corvette Stingray is really three cars in one: It provides
the comfort and functionality of a long-distance GT car, the connectedness and infotainment of a daily driver and the acceleration,
grip and braking of a capable track car,” said Harlan Charles, product manager.
“With the Driver Mode Selector, we wanted to give the driver an easy way
to tailor virtually every aspect of the car to fit their driving environment. The result is a more rewarding, more confident
experience, whether you’re commuting in a downpour or charging through the corkscrew at Laguna Seca.”
The Driver Mode Selector is easy to use via a rotary knob near the shifter. The
Tour mode is the default setting for everyday driving; Weather mode is designed primarily for added confidence while driving
in rain and snow; Eco mode is for achieving optimal fuel economy; Sport mode is for spirited road driving and Track mode is
for track use.
“Early in the development process,
we spent time on the track, driving Corvettes hard. That experience shaped many parts of the interior, such as the instrument
display in Track Mode,” said Vaughn. “At 120 mph, you experience a sort of tunnel vision, as you concentrate on
the next turn. At that moment, you don’t need to know the next song playing on the radio.”
Twelve performance parameters are adjusted with the selection of each mode, including:
· Gauge cluster
configuration: The Tour, Eco
and Weather modes feature displays for trip data, audio and navigation; Sport mode shows classic, easy-to-read
sports car gauges; and Track mode’s configuration shows a gauge design based on the Corvette Racing
C6.R race car display with lap timer
(Electronic Throttle Control): Adjusts
the throttle input curve for the selected mode for improved responsiveness
Adjusts shift comfort and shift points
· Active Fuel Management: in normal mode, the LT1 engine uses V-8 power during acceleration and V-4 power when coasting; in
Eco mode the engine remains in V-4 mode to improve fuel economy until aggressive acceleration is needed
· Exhaust (active exhaust system): The system adjusts the timing of the electronically controlled exhaust valves to enhance audible
feedback from the V-8 depending on the drive mode
limited-slip differential (Z51): Adjusts the rate at which the limited slip engages, to balance between steering response and stability in different
driving conditions; more aggressive performance in Sport and Track modes
· Steering: Assist effort is adjusted in the modes to provide
the driver with the correct steering feel for the driving condition
Ride Control: Adjusts shock
damping based on road conditions, from optimized comfort to performance driving
control: Available in Sport
and Track modes for manual and automatic transmissions, providing maximum off-the-line acceleration
handling (StabiliTrak stability control):
A “competitive” setting is available in Sport and Track modes and is more suited for on-track conditions.
It can also be disabled, giving the driver complete control
control: Weather mode tailors
traction control and engine torque for driving in inclement conditions
Traction Management: Available
in the Sport and Track modes and offers five settings of torque reduction and brake intervention for track driving.
Three configurable displays, including a pair of eight-inch screens and color
head-up display, deliver personalized information and convey the different performance parameters of each drive mode.
The two eight-inch screens offer excellent visibility in direct sunlight, with
650 cd/m2 of brightness for the one integrated into the instrument cluster and 1,000 cd/m2 of brightness for the one in the
center stack, making it among the brightest screens in the industry. The screen in the center stack also features touch-screen
control with gesture recognition and can be lowered to reveal a hidden storage that includes a USB input for device charging
The Corvette Stingray delivers an advanced infotainment system, featuring Chevrolet
MyLink and high-definition radio, as well as enhanced OnStar with 3D navigation maps. An additional USB port in the center
console, a stand-alone audio input jack and an SD card slot provide seamless connectivity.
An available premium 10-speaker audio system includes a bass box and two subwoofers
– and speakers with rare-earth magnets that deliver greater sound quality with reduced weight and size.
Every line counts on Corvette Stingray’s
functionally elegant exterior
- Aerodynamic design integrates strategies from Corvette racing
- Signature lighting includes distinctive
frosted light-emitting diode daytime driving lights, high-intensity discharge headlamps and indirect-LED
- Carbon fiber hood and removable roof
panel enhance front/rear weight balance
Corvette Stingray’s provocative exterior styling is as functional as it
is elegant, said Ken Parkinson, executive director of global design.
“Developing a new Corvette, while every designer’s dream, is not
an easy task,” Parkinson said. “The goal was a bold design statement that
embraced the advanced technology of the car, while enhancing its overall performance in everything from the wind tunnel to
the track. The result is a new Corvette Stingray – a fantastic car that breaks new ground yet remains true to the fundamental
elements that make a Corvette a Corvette.”
While no single detail is repeated from previous
generations, the new Corvette Stingray include the distinctive profile defined by a long dash-to-axle ratio and the greenhouse
evoking the canopy of a fighter jet with dual-element taillamps. To this foundation, designers built a form vocabulary from
two very different sources: aerospace and nature.
“For the new Corvette to be called a Stingray, it had to deliver
an incredible, purposeful visual impact – just as the original did in 1963,” said Tom Peters, exterior design
director. “That visual impact is evident in fighter jets and the Stingray animal itself. Their beauty comes from their
purpose, designed to cut through air or water as quickly and efficiently as possible. As with aircraft and living forms, every
transition on every surface of the Corvette Stingray serves a purpose executed with beauty and proportion.”
Lighting is a signature element of the Corvette Stingray’s design and reinforces
its high-tech aesthetic. At the front, indirect white LED lamps form a distinctive daytime styling cue. They are set in a
black-chrome lamp housing with standard HID projector headlamps. The turn signals feature edge-lit amber LED lighting.
All-new, dual-element taillamps represent the greatest departure from tradition
and are among the car’s most dramatic elements. The three-dimensional, sculpted lenses house innovative indirect LED
lighting. The state-of-the-art lighting uses hidden LED lamps that cast their light up from the bottom of the housing into
a reverse reflector, creating an even glow. LED lamps are also used for the white backup lamps. The taillamps integrate functional
aircraft-style air outlets for the available differential and transmission coolers.
“From the front or rear, the signature lighting
brings the new Corvette to life,” said Peters. “It looks beautiful, sinister and more than a little intimidating. It gives the Corvette a nighttime appearance unlike anything else on the street.”
When it comes to aerodynamics, the new Stingray is in a league of its own. Advanced
computer-aided modeling programs were employed to predict and track airflow over, under and through the new Corvette’s
body. Engineers and designers also relied on data gleaned from the Corvette Racing program – the most successful program
ever in the American Le Mans Series and the 2012 GT class champion – to help balance front and rear grip for high-speed
Many hours were spent in the wind tunnel hand-sculpting surfaces for aesthetics
and performance. Functional exterior elements include:
· All models have a new grille/radiator arrangement
and hood vents. Venting air out of the hood reduces total front-end lift for improved steering response at high speeds
· The front fender side coves also help vent underhood air pressure to reduce
· Models with the automatic transmission or Z51 Performance
Package feature a functional vent on driver’s left side directing air over a heat exchanger for the transmission fluid
and a similar arrangement on the passenger side that directs air
· over a heat exchanger for the electronic limited slip differential
· Airflow through the differential and transmission heat exchangers exit
through the aircraft-inspired taillamp vents and lower-rear fascia air outlets
· The Z51 Performance Package also includes brake-cooling
ducts, a unique rear spoiler and additional air deflectors for enhanced track capability.
“Every square inch of
the 2014 Corvette’s exterior is designed to enhance high-performance driving,” said Kirk Bennion, exterior design manager.
“The team delivered a great balance of low drag for efficiency and performance elements for improved
stability and track capability – all in a sculpted design that
excites in all the ways that a Corvette has for six decades.”

from the Corvette Racing program to produce an ideal 50/50 weight balance and to deliver a world-class power-to-weight ratio.
has a long history of using racing to improve production cars, and nowhere is that more evident than with Corvette,”
said Jeuchter. “We continually apply technologies and strategies developed for
Corvette Racing directly to the production car. That influence can be seen in virtually every aspect of the new
Corvette Stingray, from the aerodynamic design to the use of carbon fiber, to the cooling techniques and
even in the brake system.
technologically advanced foundation is an all-new aluminum frame structure that is 57 percent stiffer and 99 pounds (45 kg)
lighter. The greater torsional rigidity reduces unwanted noise and improves ride and handling.
to the previous generation, which used continuous hydroformed main frame rails with a constant 2mm wall thickness, the new
Corvette’s frame features main rails composed of five customized aluminum segments, including aluminum extrusions at
each end, a center main rail section and hollow-cast nodes at the suspension interface points. Each segment is tuned –
varying in thickness from 2mm to 11mm – tailoring the gauge, shape and strength properties to optimize the requirements
for each frame section with minimal weight.
frame is assembled at an all-new welding shop at the Bowling Green Assembly Plant using a unique laser welding process in
which a computer-controlled beam of high energy joins the components with exceptional precision and tolerances of about 0.001-inch.
the frame’s greater strength and lower weight are complementing chassis elements, including hollow-cast aluminum front
and rear cradles that are approximately 25-percent lighter and 20-percent stiffer than the solid cradles used on the previous
The innovative use of materials includes a standard carbon fiber hood and roof panel, as well as underbody panels created
with carbon-nano composite technology, an advanced blend of traditional composite material and carbon fiber, which allows lighter underbody panels without a
loss of strength or stiffness. Fenders, doors, rear quarter panels and the rear hatch
panel are made with lighter-density Sheet Molded Compound than the previous generation. Combined, these
materials save approximately 37 pounds (17 kg) versus the previous body structure.
The lightweight elements of the Stingray
contribute to the ideal 50/50 weight balance. Combined with its estimated 450 horsepower (335 kW), the new Corvette delivers
a better power-to-weight ratio than the Porsche 911 Carrera or Audi R8.
Those 450 horses are generated by
an all-new LT1 6.2L Small Block V-8 engine, which produces an estimated 450 lb.-ft. of torque (610 Nm). More importantly,
it generates 50 lb.-ft. more low-end torque than the previous 6.2L engine, matching the 7.0L LS7 engine from the 2013 Corvette
Z06 from 1,000 to 4,000 rpm.
The engine’s performance comes
from combining advanced technologies like direct injection, Active Fuel Management and continuously variable valve timing
with an advanced combustion system. More than 10 million hours of computational analysis went into the new Small Block’s
design, including more than 6 million hours alone on the combustion system.
The LT1 is backed by a choice of active exhaust systems that are less restrictive
than the previous generation, due in part to an increase in diameter from 2.5 inches to 2.75 inches. The standard system offers
a 13-percent improvement in airflow and features a pair of butterfly valves that contribute to greater refinement at cruising
speeds when the engine is operating in fuel-saving V-4 mode.
An available dual-mode active exhaust system offers a 27-percent improvement
in airflow. It features two additional valves that open to a lower-restriction path through the mufflers. When open, these
valves increase engine performance and produce a more powerful exhaust note.
The LT1 is mated to either a six-speed paddle-shift automatic transmission or
an industry-exclusive TREMEC TR6070 seven-speed manual with Active Rev Matching. The Corvette retains its distinctive rear
transaxle layout for optimal weight balance.
The seven-speed manual incorporates rev-matching technology for upshifts and
downshifts. This driver-selectable feature can be easily engaged or disengaged via paddles on the steering wheel. The seven-speed
is used with a new dual-mass flywheel and dual-disc clutch, which deliver greater shift quality and feel through lower inertia.
The transmission with the Z51 Performance Package includes specific close-ratio gearing for more aggressive driving.
“Active Rev Matching makes the new Corvette easier and more fun to drive
in performance conditions,” said Jeuchter. “It anticipates the next gear selection and electronically ‘blips’
the throttle to match engine speed for a seamless gear change.”
six-speed Hydra-Matic 6L80 paddle-shift automatic is also available. It is optimized for use with Active Fuel Management and
features a lower-inertia torque converter for improved shift quality and shift speeds. In addition, shift feel and shift points
can be adjusted through the Driver Mode Selector.
More direct, more connected driving feel
· Third-generation Magnetic Ride Control for greater comfort and control
· Electric power steering system tailors steering response and feel
· Electronic limited-slip differential delivers optimal traction
The new Corvette Stingray’s chassis and suspension are designed to take
advantage of the lighter, stiffer structure. The reduced structural flex allowed engineers to more precisely tune the suspension
and steering for a more nimble and responsive driving experience.
important goal for the seventh-generation Corvette was to create a more intimate and connected driving experience, said Mike
Bailey, chassis vehicle system engineer. “Whether on the open road or on the track, we wanted drivers to feel comfortable
and confident behind the wheel.”
While the Corvette
Stingray retains the racing-proven short/long-arm suspension design, front and rear, the components are all-new. Improvements
to the suspension include hollow lower control arms which save approximately nine pounds (4 kg) per vehicle
and new aluminum rear toe links which save 2.4 pounds (1.1 kg) over previous steel links.
The Corvette Stingray rides on new 18 x 8.5-inch front and 19 x 10-inch rear
wheels, while models with the Z51 Performance Package roll on 19 x 8.5-inch front and 20 x 10-inch rear forged aluminum wheels.
New Michelin Pilot Super Sport run-flat tires developed specifically for the seventh-generation Corvette deliver comparable
levels of grip than the wider tires of previous models.
As a result, the track-oriented Corvette Stingray with the Z51 Performance Package is capable of 1g in cornering acceleration
– comparable to the 2013 Corvette Grand Sport. Significantly, that is achieved with narrower and lighter wheels and
tires. The reduced “footprint” reduces rolling resistance, steering effort and road noise, contributing to
a more nimble feel, more immediate steering response and greater touring comfort and efficiency.
the new Corvette’s wheelbase is approximately an inch longer than the previous generation, with front and rear tracks
that are almost an inch wider. Those changes provide a more stable feel, particularly at high speeds, while the turning radius
is decreased by approximately two feet for greater maneuverability in tight turns.
The Corvette Stingray features standard 35mm-piston Bilstein monotube shocks that connect to dual-path aluminum shock mounts that separate the shock rod and shock body load paths. The Z51 Performance Package comes with 45mm-piston
Bilstein dampers for more aggressive body control and track capability. Z51 is available with the third-generation
Magnetic Ride Control, which features a new twin-wire/dual-coil damper
system that reacts 40 percent faster, enabling improved ride comfort and body control.
The new electric power steering system offers variable ratios and variable
effort to tailor responsiveness and feel for each driving situation. It also delivers more precise control and feedback to
the driver, along with greater variability of effort for high-performance driving and greater on-center
sensitivity and linearity. Steering feel was further improved by increasing steering column stiffness by 150 percent, increasing intermediate
shaft torsional stiffness by 600 percent, and mounting the steering gear to the front cradle structure. As a result the steering
system is five times stiffer than the previous generation.
A smart electronic limited-slip differential (eLSD) is included in the Z51 Performance
Package and continuously makes the most of the torque split between the rear wheels. The system features a hydraulically actuated
clutch that can infinitely vary clutch engagement and can respond from open to full engagement in tenths of a second. It shifts
torque based on a unique algorithm which factors in vehicle speed, steering input and throttle position
to improve steering feel, handling balance and traction.
limited-slip differential transforms the Stingray by optimizing handling for the driving situation,” said Mike Bailey,
vehicle systems engineer, chassis. “By continuously modulating the torque split between the rear wheels, the eLSD can
improve traction accelerating out of corner, improve stability on the highway and enhance steering turn-in and responsiveness.”
The eLSD is
fully integrated with StabiliTrak and Performance Traction Management systems. Its calibrations vary among three modes, based
on the Drive Mode Selector setting:
1 is the default setting for normal driving and emphasizes vehicle stability
· Mode 2 is engaged when electronic stability control is turned off in the Sport or Track Driver Modes. This calibration
enables more nimble turn-in and traction while accelerating out of a corner
3 is automatically selected when Performance Traction Management is engaged. This calibration has the same function as Mode
2, but is fine-tuned to work with Performance Traction Management.
brakes, with four-piston fixed calipers derived from racing, deliver exceptional stopping power on the street or track. System
· 12.6-inch (320 mm) front rotors and 13.3-inch (338 mm) rear rotors are standard and have 35
percent more swept area than previous-generation brakes. Consequently stopping distance is improved 9 percent
· Dual-cast, slotted 13.6-inch (345 mm) front rotors and 13.3-inch (338 mm) slotted rear rotors are included
with Z51 Performance Package. They have 6percent more swept area than the previous-generation Grand Sport
and are cooled front and rear for improved track capability. Consequently stopping distance is improved 5 percent
· All brake packages have fixed front and rear calipers are stiffer for more
even pad wear, reduced drag and improved modulation.
