Porsche has pulled the wraps off a pair of new 911 models that fit into the line of venerable sports cars.

Coming to showrooms in November, the 911 Carrera GTS can be specified as a hardtop coupé or convertible and with rear-wheel or all-wheel drive.

Every model offers 430hp on tap, that’s 30hp more than the 3.8-liter flat-six engine usually puts out and that translated into a faster 0-100km/h time and a higher top speed, too.

The coupe can hit 100 km/h in just 4.0 seconds while the convertible needs 0.2 seconds more to hit the same speed.

PORSCHE promises that all variations of the GTS will break the 300km/h (186mph) barrier and that the rear-wheel drive hardtop when specified with a seven-speed manual rather than paddle shift double-clutch automatic transmission is good for 306 km/h and beyond.

As well as greater straight-line speed, all GTS models get the Sport Chrono package (standard on the 911 Turbo) and the Porsche Active Suspension Management (PASM) system as standard, so a lower ride height and even better handling in the curves.

To subtly let other 911 drivers know that your car is slightly more special, the GTS has a specially designed front bumper, tinted headlamps, black 20-inch alloy wheels and black chrome-plated exhausts.

The 911 Carrera GTS will make its first public appearance at the LA Motor Show in November before hitting showrooms in Europe. Pricing will start at $115,195 for the coupe and $127,095 for the convertible.
