What is it?
This is the open-top version of the latest all-wheel-drive 911, and it’s also a chance to try the revised 997 in entry-level form with the 3.6-litre engine and a conventional manual gearbox rather than the new double-clutch PDK unit.
Don’t scoff at the thought, either. Choice of gearbox aside, this is just about the best-selling of all 911 variants, and Porsche has proved in the past that it can do open-top cars that don’t wobble and shake (much).
It may not be the 911 of choice for enthusiasts, but it’s still a 911, and that means it’s still a bit special.
Like the C4 coupé, very little has changed on the outside compared with the previous model – new LED lights, a reflective strip running across the rear – but quite a bit has been going on under the skin.
Although the impressively rigid structure remains unchanged, the C4 cabrio benefits from the same new electronically controlled all-wheel drive system as the C4 coupé, as well as the new direct injection flat six engines that are being rolled out across the 911 range.
It also gets a 44mm wider rear track than the rear-drive model. For the pleasure of open-top 911 motoring you’ll pay around £7k more than for the equivalent coupé, and all-wheel-drive security demands a premium of around £4300 over the equivalent two-wheel driver.
What's it like?
The cabriolet is 85kg heavier, model for model, than the C4 coupé, which isn’t a bad penalty to pay, but the extra weight does have the effect of blunting performance just a little and making the open car feel a little softer riding.
The entry-level 341bhp 3.6-litre engine is a cracker – arguably sweeter and more tuneful than the 3.8 in the S – and when linked to Porsche’s slick six-speed manual gearbox the C4 cabrio doesn’t feel all that much slower than the more powerful 3.8. Which is to say that it’s actually very quick.
Specifying the optional double-clutch PDK gearbox in theory shaves a couple of tenths off the 0-60mph time, but on the road it’s the conventional manual gearbox that works better with the less powerful engine for a crisper, more energetic and more involving experience.
There’s no escaping the fact that the cabrio, being less rigid than the coupé, doesn’t cope with bumpy roads quite as well, sending little tremors through the steering column and the odd shudder through the structure, but this is still a very sporting car and a pleasure to drive.
The PTM all-wheel drive system gives the car incredible grip and stability, albeit at the expense of more understeer than the RWD models and more weight to the steering.
Lower the more durable fabric roof – a process that takes 20 seconds – and there’s more wind buffeting in the cabin than you might expect of an upmarket convertible – a wind deflector might be useful - but the upside is that you can hear the howling, growling flat six better than ever.
It’s a more visceral and less relaxing experience than you’d get in, say, a Jaguar XKR convertible, but none the worse for it.

If you don't like the design of the 911 buy something else. One of the reasons for its success is that the design changes are evolutionary. This is quite different from BMW where the changes seem arbitrary from one generation M3 to another - a Japanese school of design principles - rather than understanding its strengths and building upon them. What next: someone asking for a mid-engined 911???
Re: Porsche 911 Carrera 4 Cabriolet
I'd love to see them try to package a folding hard-top (maybe have it fold into the front boot, since Porsche like to do things the wrong way round with the 911 :-) The 911 cabrio suffers from fat-a*se syndrome even with a rag top, and the white of the test car makes the modern 911's styling issues even more obvious. Can't help thinking it's time for Porsche to stop living in the past and give the 911 a fresh design.
Mind you, the Ferrari California is pig-ugly too and much more expensive, so there's no rush!
Re: Porsche 911 Carrera 4 Cabriolet
Autocar should have tested the current 911 Turbo vs the last. They would have found its simpler 4WD system quite a bit better. This new new new 911 will still not handle as well as an old C4S or Turbo as Porsche have not cracked how to do electronic 4WD like Nissan have. But politics is politics- there should be unbiased testing with cars.
