Superb performance, with great steering and huge grip. Simply stunning
Caters for all sizes of driver, but dashboard can be a little confusing
All good on safety, but the canvas hood is a weak point for security
Beautifully built, but Porsche reliability isn't what it once was
One of the most practical supercar drop-tops
It's annoying that you have to pay extra for Bluetooth
Performance in the faster version, the Carrera S, is eye-watering, with 0-62mph reached in just 4.7 seconds. Not that the Carerra is slugglish - it's sprint time is only 0.3sec off the S's, so most will find the lower-powered car fast enough. The optional seven-speed PDK gearbox is flattering to drivers and makes the natural choice for city dwellers.
The 911 Cabriolet has a comfortable ride, yet it still handles incredibly well. There's a huge amount of grip in corners and sharp, precise steering, which makes it easy to explore the car's talents. Okay, so the Cabriolet isn't quite as poised or agile as an Audi R8 Spyder, but it's far easier to drive smoothly at low speeds.
The roof is designed with individual panels that abut beneath the fabric. This brings wind noise down almost to the level of hard-top car. The windbreak is effective at keeping out draughts when the roof is open, when you get the full benefit of the engine's howl. Only road noise lets the side down.
The 911's interior looks and feels stunning. The dashboard layout is good, although there are a few too many similar-looking buttons on the centre console. There's a good range of adjustment for the steering wheel and for the comfortable, supportive seats, and the view out of the back is far better than in most drop-top supercars.
The front boot holds much more than you'd imagine at first glance, and since the rear seats are only really big enough for small children, you can use this area to boost luggage space if necessary.
The 911 Cabriolet comes reasonably well equipped as standard but it's disappointing that you have to pay extra for Bluetooth. You'll also have to pay extra for heated seats, metallic paint and a multi-function steering wheel.
The 911 is built from high-quality materials to exacting standards inside and out. However, a question mark hangs over Porsche's mechanical reliability as it came 20th out of 36 manufacturer's in What Car?'s latest reliability survey. Fortunately, both the active and passive safety systems on the Cabriolet are first class, and in many cases levels of intervention can be adjusted to driver preference. Porsche's tracker system is standard.
Porsche controls its supply of cars better than most, so there's little chance of a discount from dealers. On the positive side, this means residual values are sky-high. Meanwhile, the 911 may not be exactly frugal on fuel but it's not as thirsty as many other supercars. Porsche's servicing costs are modest compared to rivals, too.
