Porsche AG packs more power into the 911 GT3, set for introduction in its next-generation form at the Geneva auto show in March.

The German auto maker up-sizes the engine in the new ’10 model to 3.8L from 3.6L and applies its VarioCam variable-timing technology on both the intake and exhaust valves, squeezing 435 hp out of the 6-cyl. boxer, 20 hp more than its predecessor.

Porsche says the powerplant delivers significantly more torque at medium speeds and can accelerate the GT3 from 0-60 mph (97 km/h) in 4.0 seconds. Top speed is 194 mph (312 km/h).

Engineers also stiffened the springs and anti-roll bars for more precise handling. The auto maker says the car still retains a comfortable ride, however, thanks to the application of Porsche Active Suspension Management adjustable-suspension technology.

Porsche Stability Management will be standard on the GT3 for the first time. The auto maker says drivers will have the ability to disengage the stability and traction controls in separate steps.

Little change has been made to the exterior, but Porsche has refined the aerodynamics, and larger vents front and rear, standard bi-xenon headlights and light-emitting-diode rear lights help freshen the look.

The GT3 will be offered with new dynamic engine mounts that use a magnetic fluid to stiffen the coupling between engine and chassis when the car is being driven aggressively. Larger brakes, with weight-saving aluminum hubs, increase stopping power. Ceramic brakes are available as an upgrade.

Among options is a new lift system that raises the front end at the touch of a button, protecting the car as it enters steep inclines or approaches a driveway. The system raises the front height 1.18 ins. (3.0 cm) at speeds up to 30 mph (48 km/h).

Expected to hit the market this fall, the new GT3 will sticker at $112,200 in the U.S.
