Chevrolet Corvette C7

The Chevrolet Corvette (C7) is the seventh generation of the Corvette sports car manufactured by American automobile manufacturer Chevrolet from 2014 until 2019. It was introduced for the 2014 model year as the first to bear the Corvette Stingray name since 1976. The first C7 Corvettes were delivered in the third quarter of 2013.

Development and introduction

GM executives began planning the next-generation (C7) Corvette sports car in 2007. The car was originally planned for the 2011 model year, but was delayed. Mid-engine and rear-engine layouts had been considered, but the front-engine, rear-wheel drive (RWD) platform was chosen to keep costs lower.

The lead exterior designer of the C7 Corvette was Hwasup Lee, whose team completed the design between 2010 and 2011. The design director for the C7 was Kirk Bennion and the design was approved by the division's design director, Tom Peters, in 2011.

The 2014 Corvette debuted on Sunday, January 13, 2013, in Detroit at the North American International Auto Show. Chevrolet also showed the new crossed flags logo for the Corvette.

While overall the C7 attempts to provide an evolutionary redesign to an iconic theme, the car's designers incorporated aggressive angular elements. The C7 received criticism for some of the more styled elements of the car. "The rear contains what will surely be the C7's most controversial styling elements. It's all creases and vents back there, with aggressive trapezoidal taillights similar to those found on the current Camaro and quadruple-barreled tailpipes lined up in a neat row in the center of the rear valance", wrote Jason Kavanagh for Edmunds. Functional aerodynamic aids are tacked on or cut into every body panel of the C7, often juxtaposed against sharp creases. This is a radical departure from the prior generations of Corvettes, whose styling had no spoiler, few body panel creases, and only semi-functional gills for front brake cooling. In addition, past Corvette models minimized the size of headlamps or even hid them altogether. The C7 reverses that minimalist styling language with intricately styled headlamps with integrated LED daytime running lights (DRL).

The C7's all-new LT1 6.2L Small Block V-8 engine develops and of torque, which can accelerate the car from 0– in 3.8 seconds. The optional Z51 Performance Package or the Grand Sport bumps up the LT1 to 460 horsepower and 465 pound-feet of torque. The C7's suspension consists of independent unequal-length double wishbones with transverse fiberglass mono-leaf springs and optional magnetorheological dampers, similar to its predecessor.

2014 model year

Production

Production and customer delivery of the 2014 Corvette Stingray Coupe began in September 2013. Corvette assembly plant tours in Bowling Green, Kentucky began in October 2013. Production of the Stingray Convertible began at the end of 2013. The fifth generation of the small block engine used in the 2014 Chevrolet Corvette Stingray was built in GM's Tonawanda Engine Plant.

The first production 2014 Chevrolet Corvette Stingray Convertible was sold in 2013 Barrett-Jackson Palm Beach to Hendrick Motorsports owner Rick Hendrick for US$1,000,000 in a Barbara Ann Karmanos Cancer institute charity lot.

A month after the first 2014 Corvette Stingray, 485 vehicles had been delivered. Of these early orders, 38% included 7-speed manual transmission, and 75% included the Z51 Performance Package (54% also selected the magnetic ride suspension system).

Equipment

The 2014 Corvette features a carbon fiber hood and removable roof panel. Its fenders, doors, and rear quarter panels remain fiberglass composite. The C7 uses Aerogel, a material developed by NASA, to keep heat from the transmission tunnel from transferring into the cabin. The under-body panels are made of "carbon-nano" composite. The chassis is made of hydro-formed aluminum. The rear tail lights use indirect LED technology.

Despite the increased use of aluminum and other light weight materials, the overall weight of the car remains the same as that of the previous generation (C6). The C7 Corvette offers a seven-speed manual transmission made by Tremec that implements active rev matching. The Corvette also provides a driver mode selector with five settings: Weather, Eco, Tour, Sport, and Track mode. The hood and side vents and inlets assist in cooling and aerodynamic stability. The interior features a driver display that allows the driver to select from several modes with up to 69 different sources of information, ranging from an interactive performance timer to a tire tread temperature display. Two seat options are available: a touring seat for everyday use, and a competition sports seat for track driving with pass-throughs for a racing harness.

The 2014 Corvette LT1 engine, the first of the fifth generation family of small block engines, retains the push-rods acting on overhead valves design. It implements direct fuel injection, Active Fuel Management (cylinder deactivation), and continuously variable valve timing.

2015 model year

Production

In 2015, the 8L90 eight-speed automatic transmission was available as an option for all Corvette models. The 8L90 is built at GM's Toledo, Ohio, transmission facility.

Equipment

Major changes for the 2015 model year, in addition to the reintroduction of the Z06, were limited to the introduction of the 8L90 automatic transaxle (replacing the 6L80 transaxle), as well as the dual mode exhaust becoming standard on Z51 cars.

Performance Data Recorder

The Performance Data Recorder (PDR) is an optional system that allows Corvette drivers to record performance data while driving and review the results.
A 720p high-definition camera mounted within the windshield header trim records the driver's point-of-view through the windshield, with audio recorded via a dedicated microphone in the cabin. The system uses a dedicated GPS receiver more precise than the one in the navigation system. The recorder can access vehicle information, ranging from engine speed and transmission-gear selection to braking force and steering-wheel angle. It uses a dedicated SD-card for recording and transferring video and vehicle data.

The PDR system can record video with three data overlay options, each rendered in real time. "Track Mode" shows the most data on the screen, including speed, rpm, g-force, a location-based map, and lap time. "Sport Mode" shows fewer details but includes key data including speed and g-force. "Touring Mode" shows no data; it simply records and displays video and audio of the drive. Additionally, "Performance Mode" records performance metrics, such as 0 to acceleration, 1/4-mile speed and elapsed time, and runs.

The PDR vehicle data can be viewed in the included "Cosworth Toolbox" software. The application overlays recorded laps on a satellite map of the track, and allows lap-by-lap comparison of vehicle speed, time, and cornering force. The video can be viewed on the Corvette Stingray's eight-inch color touchscreen (when the car is parked), or transferred to a computer for editing and sharing on social media.

Models and special editions

Z06

For the 2015 model year, a performance version of the Corvette called the Z06 was introduced at the North American International Auto Show. The Z06 comes with a supercharged and intercooled LT4 V8 engine with Rotocast A356T6 aluminum cylinder heads and a 1.7-liter Eaton R1740 TVS Supercharger, which generates at 6,400 rpm and at 3,600 rpm of torque, giving the Z06 a top speed of . The Z06 is available with a Tremec seven-speed manual with rev-matching technology or a Hydramatic 8L90 eight-speed automatic transmission with paddle shifters.

Changes to the body of the Z06 include a removable carbon fiber roof panel, a front splitter, a unique carbon fiber hood with a larger vent, larger front fender vents and unique air blades over the inlets on the rear fenders, a larger unique rear spoiler, and rear-fascia openings that are larger than that of the Stingray. The redesigned mesh pattern on the front fascia allows for maximum airflow to the supercharger's intercooler heat exchanger, while dedicated brake-cooling intakes and wider grille outlets on the bottom serves as air diffusers. It rides on 19×10-inch front and 20×12-inch rear spin-cast aluminum wheels on Michelin Pilot Sport P285/30ZR19 front and 335/25ZR20 rear tires.

Inside the Z06, there are a choice of two magnesium frame seats (GT seat or a Competition Sport seat with more aggressive side bolstering), a steel-reinforced grab bar on the center console for the passenger, soft-touch materials on the edge of the console, and a fully wrapped interior with Nappa leather, aluminum, carbon fiber, and microsuede, depending on the trim level.

Mechanical features of the Z06 include Brembo brakes (371×33-mm front and 365×25-mm rear two-piece steel disc brakes, aluminum six-piston front and four-piston rear fixed calipers), uniquely calibrated SLA-type front and rear suspension design, Magnetic Ride Control dampers, electronic limited-slip differential (eLSD) integrated with electronic stability control, and Performance Traction Management.

The US model of the Z06 went on sale in January 2015, with a base price of US$78,995. Chevrolet offered buyers of the Z06 an opportunity to personally assemble the engine used in their cars at the Bowling Green, Kentucky assembly plant where they are built as part of a US$5,000 package beginning in March 2015.

The Corvette Z06 Convertible includes a power-folding top that can activate at driving speeds up to , as well as repositioned safety-belt mounts.

A total of 95 2019 Corvettes were equipped with the Drivers Series Package. Of those, 14 had the Antonio Garcia livery, 21 had the Tommy Milner livery, 25 had the Jan Magnussen livery, and 35 had the Oliver Gavin livery.

ZR1

The Corvette C7 ZR1 was unveiled at the 2017 Dubai Motor Show for the 2019 model year. The ZR1 is heavily based on the Z06 platform with many noticeable changes, including the all-new pushrod ''LT5'' V8 engine equipped with a Eaton supercharger that is 52% larger than that of the Z06 along with a new fuel injection system. The new engine is rated at at 6,300 rpm and of torque at 4,400 rpm. The ZR1 also includes an improved engine cooling system with large vents in the front bumpers and on the hood, a larger intercooler, and four more radiators, bringing the total count to thirteen.

The ZR1's aero package was developed in collaboration with Pratt & Miller's Corvette racing team in wind tunnels. It includes a large rear wing bolted directly on the chassis, a front splitter, and a new front underbody spoiler in order to balance out the excess drag. Other changes include an active exhaust system and an upgraded crankshaft, all of which help propel the car to a top speed of with the low rear wing.

The ZTK Performance Package is an optional aero package for the ZR1. It adds a higher fixed rear wing which generates 60% more downforce than the Z06 with the Z07 package, but also reduces top speed due to aerodynamic drag. The ZTK package also adds carbon fiber front splitter end caps. With the combination of the high rear wing and front underbody spoiler, the ZR1 produces of downforce at top speed. The ZTK package also fits the ZR1 with Michelin Pilot Sport Cup 2 tires instead of the standard Michelin Super Sport tires, and specific chassis and magnetic ride control settings for better cornering.

Despite the extensive use of carbon fiber, the ZR1 is heavier than the Z06 at due to added fluids for the cooling system. The ZR1 is available with a 7-speed Tremec TR-6070 manual transmission with rev-matching technology or an 8-speed GM 8L90 automatic transmission with paddle shifters, which are the same as those found in the Z06. The ZR1 comes with carbon ceramic brakes, double wishbone suspension system and magnetic ride control system as standard with optional brake caliper colors and wheels. The interior includes Nappa leather upholstery, heated seats, carbon fiber rimmed steering wheel and Bose sound system as standard with a variety of performance and comfort options available. The ZR1 went on sale in Q2 2018.

A convertible version of the ZR1 was unveiled at the 2017 Los Angeles Auto Show. Performance figures remain the same as the coupe, but the convertible weighs more than its coupe counterpart due to structural reinforcing components.

Racing

C7.R

The racing version of the 2015 Corvette Z06, called the C7.R, was unveiled at the 2014 North American International Auto Show. Modifications over the Z06 include increased cooling and aerodynamic downforce, including similar front splitters, rocker panels, and front- and rear-brake cooling ducts; a 5.5-litre LS7.R naturally aspirated V8 engine developed specifically for the C7.R having a power output of , modified suspension system to accommodate wider racing tires and larger brakes, air intake openings on each of the rear quarter panels above the brake ducts, a fixed motorsport rear wing, and larger radiator inlets.

C7 GT3-R

The C7 GT3-R (sometimes stylized as C7 GT3/R) was a GT3 adaptation of the C7 unveiled by Callaway Engineering on October 3rd, 2015 at the final round of the 2015 ADAC GT Masters at the Hockenheim circuit. This also marked the first time a factory-backed Corvette was built by a company other than Pratt & Miller. It uses a 6.2L Chevrolet-based V8 engine from Dutch firm APP Racing Engines, and produces and depending on air restrictors, mated to a X-Trac 6-speed gearbox.
