Porsche revealed the 992-series Porsche 911 in November last year, and it didn’t take them long to add the new Porsche 911 Cabriolet to the range. It includes all the new features of the latest coupe 911, along with Cabriolet-specific features such as new hydraulics that get the roof opened and closed faster than ever.

The automatic soft top has an integrated glass rear window, while the roof structure contains magnesium surface elements known as bows, which reliably prevent ballooning of the roof at high speeds. The top can be opened or closed at speeds up to 50 km/h, and new hydraulics reduce opening time to around 12 seconds, while an electrically extendable wind deflector ensures that necks are shielded from wind impact.

The 911 Cab is initially available as a Carrera S with rear-wheel drive and Carrera 4S with AWD. As per the Coupe, both rely on a 3.0 litre twin-turbo boxer-six making 450 PS at 6,500 rpm and 530 Nm of torque from 2,300 to 5,000 rpm. Efficiency and emissions have been improved by a better injection process; other optimisation measures have also been implemented, such as a new layout for the turbochargers and charge air cooling system.

Power is delivered by a new eight-speed dual-clutch transmission. The Carrera S accelerates from 0-100 km/h in 3.9 seconds (3.7 seconds with optional Sport Chrono Package) and can reach speeds up to 306 km/h. The Carrera 4S is a tenth faster in the sprint and does 304 km/h max. This is a tenth or two slower than the Coupe (depending on S/4S and SC), which is expected.

Porsche says that the new engine mounting position makes the Cabriolet even more torsionally rigid than its predecessor. For the first time, Porsche Active Suspension Management (PASM) sport chassis is available for the Cab. The springs used for this are harder and shorter, the front and rear anti-roll-bars are more rigid, and the chassis overall has been lowered by 10 mm. These provide a more neutral feel on the road, with better weight distribution, it is claimed.

The new 911 Cabriolet looks wider and more muscular than its predecessor (is that rear hump also bigger than ever?), and wider wings arch over the 20-inch front wheels and 21-inch rear wheels. The RWD models now match the bodywork width of the existing AWD cars, and the rear axle is 44 mm longer.

The rear end is dominated by the wider, variable-position spoiler and the cool full-width light bar. With the exception of the front and rear sections, the entire outer skin is now made from aluminium.

There’s plenty of kit, but here are a few highlights. Porsche has developed Wet Mode, which is included as standard. This function detects water on the road, preconditions the control systems accordingly and warns the driver, who can then set the car up to focus on safety, by simply pushing a button or using the mode switch on the steering wheel (Sport Chrono pack).

Other standard safety kit include a camera-based warning and brake assist system (detects pedestrians and cyclists too), and a park assistant system with reverse camera. Options include Night Vision Assist with thermal imaging camera, as well as adaptive cruise control with automatic distance control, stop-and-go function and reversible occupant protection.
