Performance Data Recorder
The award-winning, industry-first Performance Data Recorder – or PDR – enables users to record high-definition video, with telemetry overlays, of their driving experiences on and off the track. It was developed with Cosworth, the motorsports-engineering company that supplies the Corvette Racing team’s data acquisition and telemetry electronics system.
The PDR system includes three major components, all seamlessly integrated into the Corvette Stingray’s interior. First is a high-definition camera, mounted within the windshield header trim, which records the driver’s point-of-view through the windshield. Audio is recorded via a dedicated microphone in the cabin.
Second is a self-contained telemetry recorder, which uses a dedicated GPS receiver that operates at 5 hertz, or cycles per second – five times faster than the in-dash navigation system, which allows more precise positioning and corner traces. Finally, the system features a dedicated SD-card slot in the glove box for recording and transferring video and vehicle data. Recording time depends on the capacity of the memory card, but an 8-gigabyte card can record approximately 200 minutes, while a 32-GB card stores up to about 800 minutes – more than 13 hours of driving time.
The PDR system can record video with three data overlay options, each rendered in real time:
Track Mode – shows the maximum level of data on the screen, including speed, rpm, g-force, a location-based map, lap time and more
Sport Mode – shows fewer details on the overlay but includes key data including speed and g-force
Touring Mode – simply records and displays video and audio of the drive with no data overlay
Performance Mode – records performance metrics, such as 0 to 60 mph acceleration, 1/4-mile speed and elapsed time, and 0-100-0 mph runs.
The video can be viewed on the Corvette Stingray’s eight-inch color touchscreen when the car is parked, or downloaded to a computer for further editing, and for sharing video via social media sites. For users who want a more in-depth understanding of their performance, the PDR vehicle data can be opened in the included “Cosworth Toolbox” software, which combines Cosworth’s professional-level motorsport data analysis with an easy-to-use graphic interface.
Eight-speed Automatic Transmission
The 2015 Stingray is offered with a standard seven-speed manual transmission with Active Rev Match, or an all-new 8L90 eight-speed paddle-shift automatic transmission designed to enhance both performance and efficiency.
There’s no trade-off in drivability with the new 8L90 eight-speed automatic transmission – it was designed to deliver performance on par with dual-clutch designs, but without sacrificing refinement. It is also the highest-capacity automatic transmission ever offered in a Chevrolet car.Featuring four gearsets and five clutches, creative packaging enables the GM-developed eight-speed automatic to fit the same space as the six-speed automatic used in the 2014 Corvette Stingray.
Extensive use of aluminum and magnesium make it more than eight pounds (4 kg) lighter than the six-speed. Along with design features that reduce friction, the 8L90 is expected to contribute up to 5-percent greater efficiency, when compared with a six-speed automatic.
For performance driving, the transmission offers full manual control via steering wheel paddles, and unique algorithms to deliver shift performance that rivals the dual-clutch/semi-automatic transmissions found in many supercars – but with the smoothness and refinement that comes with a conventional automatic fitted with a torque converter.
In fact, the 8L90’s controller analyzes and executes commands 160 times per second, and wide-open throttle upshifts are executed up to eight-hundredths of a second quicker than those of the dual-clutch transmission offered in the Porsche 911.
You won't find a more responsive high-performance automatic transmission in any other sports car on the road.
This is Love at first sight
Refined good looks from front to back.
Corvette Stingray’s provocative exterior styling is as functional as it is elegant. It makes a bold design statement that embraces the advanced technology of the car, while enhancing its overall performance in everything from the wind tunnel to the track.
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 black-chrome lamp housings with standard HID projector headlamps. The turn signals feature edge-lit amber LED lighting.
The dual-element taillamps feature three-dimensional, sculpted lenses housing 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.
Function and style together at last.
All Corvette Stingray models with the Z51 Performance Package feature integral coolers for the rear differential and transmission (the transmission cooler is also included with the optional automatic transmission). For the 2015 Stingray Coupe, the air intakes are integrated on the rear quarter panels; and on convertible models, the air intakes are integrated into the underbody.
Airflow through the differential and transmission heat exchangers exits 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. These additions increase performance & efficiency, and look good doing it. Exterior colors include: Laguna Blue Tintcoat, Daytona Sunrise Orange Metallic, Velocity Yellow Tintcoat, Arctic White, Blade Silver Metallic, Black, Shark Gray Metallic, Crystal Red Tintcoat, Torch Red and Night Race Blue Metallic.

The 460-horsepower LT1 V8 Engine Delivers The Ultimate Bang For The Buck.
The Corvette Stingray’s 455 horses are generated by the LT1 6.2L Small Block V-8 engine, which also produces 460 lb-ft of torque (624 Nm). Its performance comes from combining advanced technologies such as direct injection, Active Fuel Management (cylinder deactivation) and continuously variable valve timing with an advanced combustion system. Z51-equipped models include a dry-sump oiling system.
The LT1 is backed by a choice of active, 2.75-inch-diameter exhaust systems. The standard system 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. The available performance variable-mode active exhaust system has 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 – while also raising the engine’s output to 460 horsepower (343 kW) and 465 lb-ft of torque (630 Nm).
The LT1 is offered with an all-new seven-speed manual transmission with Active Rev Matching. It 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.

Advanced Combustion System
Direct injection is all-new to the engine architecture and is a primary contributor to its greater combustion efficiency by ensuring a more complete burn of the fuel in the air-fuel mixture. This is achieved by precisely controlling the mixture motion and fuel injection spray pattern. Direct injection also keeps the combustion chamber cooler, which allows for a higher compression ratio. Emissions are also reduced, particularly cold-start hydrocarbon emissions, which are cut by about 25 percent.
Active Fuel Management (AFM) - a first-ever application on Corvette - helps save fuel by imperceptibly shutting down half of the engine's cylinders in light-load driving.
Continuously variable valve timing, which GM pioneered for overhead-valve engines, is refined to support the LT1 AFM and direct injection systems to further optimize performance, efficiency and emissions.
11.5:1 Compression Ratio
These technologies support the all-new, advanced combustion system, which incorporates a new cylinder-head design and a new, sculpted piston design that is an integral contributor to the high-compression, mixture motion parameters enabled by direct injection.
The LT1 head features smaller combustion chambers designed to complement the volume of the unique topography of the pistons' heads. The smaller chamber size and sculpted pistons produce an 11.5:1 compression ratio, while the head features large, straight and rectangular intake ports with a slight twist to enhance mixture motion. This is complemented by a reversal of the intake and exhaust valve positions, as compared to the previous engine design. Also, the spark plug angle and depth have been revised to protrude farther into the chamber, placing the electrode closer to the center of the combustion to support optimal combustion.
The new LT1 is the third engine in the Corvette's history to be so-named, with previous versions introduced in 1970 (Gen 1) and 1992 (Gen 2). All iterations of the LT1 - and all Small Block engines - have shared a compact design philosophy that fosters greater packaging flexibility in sleek vehicles such as the Corvette.
All-Aluminum Block and Oil Pan
All-aluminum block and oil pan: The Gen 5 block was developed with math-based tools and data acquired in GM's racing programs, providing a light, rigid foundation for an impressively smooth engine. Its deep-skirt design helps maximize strength and minimize vibration. As with the Gen 3 and Gen 4 Small Blocks, the bulkheads accommodate six-bolt, cross-bolted main-bearing caps that limit crank flex and stiffen the engine's structure. A structural aluminum oil pan further stiffens the powertrain.
The block features nodular iron main bearing caps, which represent a significant upgrade over more conventional powdered metal bearing caps. They are stronger and can better absorb vibrations and other harmonics to help produce smoother, quieter performance.
Compared to the Gen 4 engine, the Gen 5's cylinder block casting is all-new, but based on the same basic architecture. It was refined and modified to accommodate the mounting of the engine-driven direct injection high-pressure fuel pump. It also incorporates new engine mount attachments, new knock sensor locations, improved sealing and oil-spray piston cooling.
Compared to the Gen 4 Small Block, the camshaft remains in the same position relative to the crankshaft and is used with a new rear cam bearing, but it features an all-new "tri-lobe" designed lobe which exclusively drives the engine-mounted direct injection high-pressure fuel pump, which powers the direct-injection combustion system. The cam's specifications include 14mm/13.3mm (0.551/0.524-inch) intake/exhaust lift, 200/207-crank angle degrees intake/exhaust duration at 0.050-inch tappet lift and a 116.5-degree cam angle lobe separation.
Cam-Driven Fuel Pump
The direct injection system features a very-high-pressure fuel pump, which delivers up to 15Mpa (150 bar). The high-pressure, engine-driven fuel pump is fed by a conventional fuel-tank-mounted pump. The direct injection pump is mounted in the "valley" between cylinder heads - beneath the intake manifold - and is driven by the camshaft at the rear of the engine. This location ensures any noise generated by the pump is muffled by the intake manifold and other insulation in the valley.
Four-Into-One Exhaust Manifolds
The LT-1 uses a cast version of the "four-into-one" short-header exhaust manifold design used on the Gen 4 LS7 engine. The cast header passages enable consistent exhaust flow into the "wide mouth" collector at the converter.
Advanced Oiling System
Advanced oiling system, with available dry-sump system: The LT1 oiling system - including oil-spray piston cooling - was also optimized for improved performance. It is driven by a new, variable-displacement oil pump that enables more efficient oil delivery, per the engine's operating conditions. Its dual-pressure control enables operation at a very efficient oil pressure at lower rpm coordinated with AFM and delivers higher pressure at higher engine speeds to provide a more robust lube system for aggressive engine operation.
Standard oil-spray piston cooling sprays the underside of each piston and the surrounding cylinder wall with an extra layer of cooling oil, via small jets located at the bottom of the cylinders. For optimal efficiency, the oil jets are used only when they are needed the most: at start-up, giving the cylinders extra lubrication that reduces noise, and at higher engine speeds, when the engine load demands, for extra cooling and greater durability.
An available dry-sump oiling system promotes exceptional lubrication system performance during aggressive driving maneuvers and high cornering loads. It includes two stages: a pressure stage and a scavenge stage. The pressure stage includes the new, dual-pressure-control and variable-displacement vane pump. Dexos semi-synthetic motor oil, with a 5W30 specification, helps reduce friction to further enhance the LT1's efficiency.
PCV-Integrated Rocker Covers
One of the most distinctive features of the new engine is its domed rocker covers, which house the, patent-pending, integrated positive crankcase ventilation (PCV) system that enhances oil economy and oil life, while reducing oil consumption and contributing to low emissions. The rocker covers also hold the direct-mount ignition coils for the coil-near-plug ignition system. Between the individual coil packs, the domed sections of the covers contain baffles that separate oil and air from the crankcase gases - about three times the oil/air separation capability of previous engines.
Intake Manifold & Throttle Body Assembly
The LT1's intake manifold features a "runners in a box" design, wherein individual runners inside the manifold feed a plenum box that allows for excellent, high-efficiency airflow packaged beneath the car's low hood line.
Acoustic foam is sandwiched between the outside top of the intake manifold and an additional acoustic shell to reduce radiated engine noise, as well as fuel pump noise.
The manifold is paired with an electronically controlled throttle, featuring an 87mm bore diameter and a "contactless" throttle position sensor design that is more durable and enables greater control.
World-class engineering inside & out
The lightest materials make the fasters cars.
Corvette Stingray coupe and convertible take advantage of lightweight materials, advanced manufacturing techniques and technology transfer from the Corvette Racing program to produce an ideal 50/50 weight balance and to deliver world-class power-to-weight ratios.
The 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’s gauge varies in thickness from 2mm to 11mm, tailored – along with the shape – to optimize the strength requirements for each frame section with minimal weight.
The aluminum frame is manufactured using innovative manufacturing processes at GM’s Bowling Green, Ky., assembly plant. The state-of-the-art facility employs several advanced joining technologies to ensure dimensional accuracy within 0.75 mm.
Each 2015 Corvette Stingray frame features:
439 spot-welds using a GM-patented process that uses a unique electrode designed specifically for aluminum
188 Flowdrill-machined fasteners, which are installed by a high-speed drill that extrudes the frame material to create a strong, integral collar that is tapped for bolt-on fasteners
113 feet of structural adhesives, used in conjunction with welding and fasteners to increase overall frame stiffness
37 feet of laser welds, which join frame sections via a precise beam of high energy that minimizes heat beyond the weld area for improved structural accuracy.
The frame’s greater strength and low weight are complemented by chassis elements also designed for low-mass strength, including hollow-cast aluminum front and rear cradles. Innovative use of materials also includes a standard carbon fiber hood on all Corvette Stingray models, and a carbon fiber roof panel on all coupes. In addition, underbody panels are created with carbon-nano composite technology, an advanced blend of traditional composite material and carbon fiber for reduced weight and improved strength. Fenders, doors, rear quarter panels and the rear hatch panel are made with light-density Sheet Molded Compound.
The ultimate Corvette driving experience
The Corvette Stingray’s chassis and suspension are designed to take advantage of the lighter, stiffer structure. Its rigidity allowed engineers to more precisely tune the suspension and steering for a more nimble and responsive driving experience. The components and their calibrations – from the brake size and damper rates to the steering system – are identical between coupes and convertible.
A racing-proven short/long-arm suspension design is used front and rear, with lightweight complementing components that include hollow lower control arms and aluminum rear toe links.
A smart electronic limited-slip differential 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 that factors in vehicle speed, steering input and throttle position to improve steering feel, handling balance and traction.
The eLSD is fully integrated with Electronic Stability Control and Performance Traction Management systems. Its calibrations vary among three modes, based on the Drive Mode Selector setting:
Mode 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 modes. This calibration enables more nimble turn-in and traction while accelerating out of a corner
Mode 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.
The right rubber for the road.
The Corvette Stingray rides on 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 – all shod with Michelin Pilot Super Sport run-flat tires developed specifically for the seventh-generation Corvette. As a result, the Corvette Stingray with the Z51 Performance Package is capable of 1.03g in cornering acceleration.
Lightning-fast dampers react to every change.
Included standard 35mm-piston Bilstein monotube shocks 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 twin-wire/dual-coil damper system that reacts 40 percent faster than previous generations, enabling improved ride comfort and body control.
Tighter steering for procise control.
Electric power steering offers variable ratios and variable effort to tailor responsiveness and feel for each driving situation. It also delivers precise control and feedback to the driver, along with great variability of effort for high-performance driving, as well as excellent on-center sensitivity and linearity.
Rock-solid stopping power.
Standard Brembo brakes, with four-piston fixed calipers derived from racing, deliver exceptional stopping power on the street or track. System highlights include:
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 6-percent 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 four-piston front and rear calipers that are stiffer for more even pad wear, reduced drag and improved modulation.
