Drivetrain

ATTESA E-TS® All-Wheel Drive (AWD) with patented independent rear-mounted transaxle integrating transmission, differential and AWD transfer case


Torque distribution – Traction/yaw-based; up to 100% rear; up to 50% front


Rigid, lightweight carbon-composite main driveshaft


Electronic Traction Control System (TCS)


High-performance 1.5-way mechanical limited-slip rear differential


Advanced Vehicle Dynamic Control (VDC) [*] with three driver-selectable modes:

Normal – for daily driving; controls brakes and engine output

R-Mode – for ultimate performance; raises the threshold at which the system intervenes

Off – disengages the VDC system


Hill start assist prevents rollback when starting on an incline


Transmission

Dual clutch 6-speed transmission with three driver-selectable modes; each transmission hand-crafted in a clean-room environment:

Normal – for maximum smoothness and efficiency, with gearshifts in less than 0.5 second

R-mode – for maximum performance with fastest shift speeds (as fast as 0.2 second)

Snow – provides gentler starting and shifting on slippery surfaces


Fully automatic shifting or full sequential manual control via steering column-mounted paddle shifters


Downshift Rev Matching


Predictive pre-shift control (in R-Mode) preselects the next gear change based on throttle position, vehicle speed, braking input and other information

Brakes

Nissan/Brembo® braking system – 4-wheel disc brakes, 15" front and rear two-piece floating-rotors with diamond-pattern internal ventilation


Super-rigid 6-piston front/4-piston rear monoblock calipers with racecar-inspired 3-point radial mounting


Suspension and Steering

Front suspension – double-wishbone with aluminum links


Rear suspension – multi-link with aluminum links


Rigid front and rear suspension subframes, assembled in high-precision jigs similar to a racecar, with 6-point mounting to body


Bilstein® DampTronic® suspension system with three driver-selectable modes:

Normal – for automatic electronic control of damping

R-mode – engages maximum damping rate for high-performance cornering

Comfort – to minimize freeway hop and ride harshness on rough roads


Hollow front and rear stabilizer bars to help maintain maximum tire contact at all four wheels during cornering


Vehicle-speed-sensitive power steering


2.4 steering-wheel turns lock-to-lock
