Fresh from its world debut in Geneva, Porsche has brought the 991-generation GT3 to America for the first time
991 GT3 is more powerful but heavier than 997 predecessor
Fixed rear wing is a prominent GT3 design feature
No manual gearboxes will be offered - a first for the GT3
Power is sent to the rear wheels through a seven-speed dual-clutch automatic gearbox
The 0-62mph time is a claimed 3.5sec and the top speed is 196mph
Cabin uses alcantara extensively
The four-wheel steer system turns the rear wheels in the opposite direction below 31mph
Above 31mph, the rear wheels turn parallel to the front to aid high-speed stability
Variable damping, torque vectoring and an LSD ae standard
A deeper front bumper, extra air intakes and wider rear track sets the GT3 apart
Power comes from a newly developed 468bhp, 324lb ft version of the 3.8-litre flat six engine found in the latest Carrera S
Suspensions overhaul reduces unsprung mass by 7kg over 991 Carrera
Rev limit is up by 500rpm on the previous GT3 to 9000rpm
The American leg of the Porsche 911's 50th anniversary is underway as the new 468bhp race-bred Porsche 911 GT3 appears at the New York motor show.
The new GT3 has been co-developed by Porsche's road and race engineers. It includes key innovations such as a new electronically controlled four-wheel steer system but does without a manual gearbox option for the first time.
The GT3 is distinguished from the standard Porsche 911 by a new aerodynamic body that includes a deeper front bumper, extra air intakes and fixed carbonfibre rear wing.
At 1430kg, it weighs more than its second-generation predecessor, something largely put down to it being 85mm longer and 44mm wider.
Power comes from a newly developed 468bhp, 324lb ft version of the 3.8-litre, direct-injection flat six engine found in the latest Carrera S.
As well as being 39bhp more powerful than the previous GT3, its rev limit is up by 500rpm to 9000rpm. Power is sent to the rear wheels through a seven-speed dual-clutch automatic gearbox. Steering wheel-mounted paddle shifters feature, and launch control is integrated into the gearbox.
The 0-62mph time is a claimed 3.5sec and the top speed is 196mph.
The suspension has been overhauled to reduce unsprung mass by 7kg compared with the 911 Carreras on which the GT3 is based. A variable damping system (PASM) is standard, as is torque vectoring (PTV Plus), which includes a locking differential.
The four-wheel steer system points the rear wheels in the opposite direction to the front wheels at speeds of up to 31mph for faster corner entry speeds. At speeds above 50mph, the rear wheels steer in parallel to improve stability.
