As a member of the "under 5" club, the XLR-V is a fast little brute, thanks to a 4.4-liter supercharged V8 engine that produces an estimated 440 horsepower at 6,400 rpm, and 425 lb.-ft. torque at 3,600 rpm. GM claims that the engine is able to deliver 90 percent of its peak torque between 2,200 and 6,000 rpm. Other changes included an expansion of the vehicle's air induction system, increasing airflow almost 30 percent. Controlling all that power is a six-speed, rear-mounted automatic transmission, which features Performance Algorithm Shifting (PAS), Performance Algorithm Liftfoot (PAL), and Driver Shift Control (DSC). PAS lets the electronic transmission controller override the automatic gear selection during closed-throttle, high-lateral acceleration maneuvers, rapidly downshifting with the release of the torque converter clutch for smooth acceleration out of a turn. PAL minimizes transmission upshifts during closed-throttle driving and cornering to maintain the correct gear. DSC allows the driver to shift gears manually via the gearshift lever. Additional differences between the XLR and the XLR-V include larger brakes and wheels.
