24 Oct 2007
Engine
VR38DETT twin-turbocharged 3.8-liter V6. 480 hp @ 6,800 rpm. 430 lb-ft torque @ 3,200 - 5,200 rpm.
Dual overhead camshafts with variable intake-valve timing.
Cast aluminum cylinder block with high-endurance/low-friction plasma-sprayed bores.
IHI twin turbochargers, one per cylinder bank.
Pressurized lubrication system with thermostatically controlled cooling.
Drivetrain
ATTESA ET-S All-Wheel Drive (AWD) with independent rear-mounted transaxle integrating transmission, differential and AWD transfer case.
Rigid, lightweight carbon-composite driveshaft between engine and transaxle.
Electronic traction control plus 1.5-way mechanically locking rear differential.
Vehicle Dynamics Control (VDC-R) with three driver-selectable settings: Normal (for daily driving, controls brakes and engine output), R-Mode (for ultimate performance, utilizes AWD torque distribution for additional vehicle stability) and Off (driver does not want the help of the system).
Hill Start Assist prevents rollback when starting on an incline. DisclaimerVDC-R cannot prevent accidents due to abrupt steering, carelessness, or dangerous driving techniques. Always drive safely.
Transmission
6-speed Dual Clutch Transmission with three driver-selectable modes: Normal (for maximum smoothness and efficiency), Snow (for gentler starting and shifting on slippery surfaces), and R mode (for maximum performance with fastest shifts).
Fully automatic shifting or full sequential manual control via gearshift or steering wheel-mounted paddle shifters.
Dual clutch design changes gears in less than 0.5 second (0.2 second in R mode).
Downshift Rev Matching (DRM).
Predictive pre-shift control (in R mode) based on throttle position, vehicle speed, braking and other information.
Wheels and Tires
20 x 9.5" (front) and 20 x 10.5" (rear) super-lightweight forged-aluminum wheels with Gunmetal Gray finish.
Exclusively developed nitrogen-filled Bridgestone RE070A high-capacity run-flat summer tires, 255/40R20 front and 285/35R20 rear.
Tire Pressure Monitoring System (TPMS).
Optional exclusively developed nitrogen-filled Dunlop run-flat all-season tires, 255/40R20 front and 285/35R20 rear (includes Bright Silver wheels).
Brakes
Brembo 4-wheel disc brakes with 4-wheel Antilock Braking System (ABS), Brake Assist, Electronic Brakeforce Distribution and Preview Braking.
Two-piece floating-rotor 15-inch front and rear discs with diamond-pattern internal ventilation.
6-piston front/4-piston rear monoblock calipers.
Steering
Rack-and-pinion steering with vehicle-speed-sensitive power assist.
2.6 steering-wheel turns lock-to-lock.
Suspension
4-wheel independent suspension with Bilstein DampTronic system with three driver-selectable modes: Normal/Sport (for automatic electronic control of damping), Comfort (for maximum ride comfort), and R mode (engages maximum damping rate for high-performance cornering).
Electronically controlled variable-rate shock absorbers. High-accuracy progressive-rate coil springs.
Front double-wishbone/rear multi-link configuration with aluminum members and rigid aluminum subframes.
Hollow front and rear stabilizer bars.
