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 performance variable-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. It also raises 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.
“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.”
The seven-speed is offered exclusively in Europe. In North America and other global markets, a
six-speed paddle-shift automatic transmission is also offered. 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.
The Corvette retains its distinctive rear transaxle layout for optimal weight balance.
More direct, more connected driving feel
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. The components
and their calibrations – from the brake size and damper rates to the steering system – are
identical between coupes and convertible.
“An important goal for the team was to create a more intimate and connected driving experience
for the new Corvette Stingray,” said Mike Bailey, chassis vehicle system engineer. “Because
they share common chassis tuning, power-to-weight ratios and structural rigidity, the coupe and
convertible feel almost identical 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 that save approximately nine pounds (4 kg) per vehicle and new aluminum rear toe
links that save 2.4 pounds (1.1 kg) over previous steel links.
