2015 Corvette Z06 is here
This morning Chevrolet unveiled the 2015 Corvette Z06, this is the first time a Z06 has offered a supercharged engine, a removable roof panel, and an available paddle-shift automatic transmission. The aluminum frame carries over from the Corvette Stingray and will also be used essentially unchanged for the Corvette Racing C7.R (Corvette’s race car) this is an amazing stiff frame and allows the corvette to handle more than 600 horsepower and still offer a removable roof panel.
“The new Z06 delivers levels of performance, technology and design that rival the most exotic supercars in the world,” said Mark Reuss, president, General Motors North America. “And the Z06 leverages the engineering expertise of GM, offering the choice of two world-class transmissions, supercar performance without supercar fuel consumption, and technologies that make it easier to fully enjoy the incredible experience of driving it.”
The heart of this beautiful super car is the all-new LT4 6.2L supercharged V-8 engine, expected to deliver an at least 625 horsepower (466 kW) and 635 lb.-ft. of torque (861 Nm). To balance performance and efficiency, the LT4 is equipped with the same trio of advanced technologies introduced on the Corvette Stingray: Direct injection, Active Fuel Management and continuously variable valve timing. These technologies – combined with the fuel-efficient multi-speed transmissions, aerodynamic design and lightweight construction – help make the new Z06 surprisingly fuel-efficient (the most fuel efficient Z06 ever).
To cover the wider tire tread, the fenders of the Z06 were extended by 2.2 inches (56 mm) at the front, and 3.15 inches (80 mm) at the rear. These extensions give the Corvette Z06 a wider, lower appearance that is further emphasized by a unique rear fascia. It incorporates the same taillamp assemblies as the Stingray, but on the Z06 the taillamps are pushed approximately three inches farther apart, toward to edges of the body.
“The Corvette Z06 is a great example of the technology transfer between racing and production Corvettes,” said Tadge Juechter, Corvette chief engineer. “First, we took what we learned on the Corvette Racing C6.R and applied that to the all-new Corvette Stingray. Then, using the Stingray as a foundation, the Z06 and C7.R were developed to push the envelope of performance on the street and the track.”
The LT4 engine also has several unique features designed to support its higher output and the greater cylinder pressures created by forced induction, including:
- Rotocast A356T6 aluminum cylinder heads that are stronger and handle heat better than conventional heads
- Lightweight titanium intake valves and machined connecting rods for reduced reciprocating mass
- High 10.0:1 compression ratio – for a forced-induction engine – enhances performance and efficiency; enabled by direct injection
- Forged aluminum pistons with unique, stronger structure to ensure strength under high cylinder pressures
- Stainless steel exhaust headers and aluminum balancer that are lighter than their LT1 counterparts
- Standard dry-sump oiling system with larger cooler capacity than Z51; used with dual-pressure-control oil pump.
“The supercharged LT4 engine delivers the greatest balance of performance and efficiency ever in the Corvette,” said John Rydzewski, assistant chief engineer for Small-Block engines. “It is one of the world’s only supercharged engines to incorporate cylinder deactivation technology, enabling it to cruise efficiently on the highway with reduced fuel consumption, but offer more than 600 horsepower whenever the driver calls up its tremendous power reserve.”
Unlike most ultra-performance cars, the Corvette Z06 offers customers the choice between two transmissions to suit their driving styles. The supercharged LT4 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.
The Z06 will offer three, increasing levels of aerodynamic downforce:
The standard Z06 features a front splitter, spats around the front wheel openings, a unique carbon-fiber hood with a larger vent, and the rear spoiler from the Corvette Stingray’s Z51 Performance Package
An available carbon-fiber aero package (in either black or a visible carbon-fiber finish) adds a carbon fiber front splitter with aviation-style winglets, carbon fiber rocker panels, and a larger rear spoiler with a fixed wickerbill – a small, vertical tab at the edge of the spoiler that significantly increases downforce
The available Z07 package adds a larger winglets to the front splitter, along with an adjustable, see-through center section on the rear spoiler for track use; with this package, the Corvette Z06 delivers the most amount of aerodynamic downforce of any production car that GM has tested.
Chevrolet has been producing cars that will not be beat and do not require compromise…maybe this is what the mean when they say find new roads? The new Z06 is an amazing car and we cannot wait until the first one arrives here.
