Originally the 350Z Roadster was offered with a 280bhp 3.5-litre V6 engine linked to a six-speed manual gearbox – just the same as the coupe. Despite having no roof, the convertible version is actually heavier than the coupe (due to extra body stiffening), however in everyday driving there’s no noticeable difference in performance. The power delivery is mightily impressive and the engine note sounds even better with the roof down.

The only problem part of the package is the gearchange: it could be smoother, especially when changing down and is awkward in traffic. The 2006 model benefits from a power upgrade to 300bhp. It has to be revved harder, so is a little less relaxing to drive, but is faster, the 0-62mph sprint time being reduced to from 6.4 to 6.2 seconds. 2007 saw another increase in performance thanks to an extensively revised engine that needs a bonnet bulge for it to fit in the engine bay.

Power is increased to 313bhp, and the 0-62mph sprint time is reduced by 0.1 seconds with it being noticeably keener to accelerate.

The overall feel of the coupe has been carried over, with sharp steering and a stiff feeling chassis. The body has been strengthened to reduce flexing and – on the whole – it has worked. Once the roof is down, the 350Z feels refined and has very little wind buffering or body flexing – even at higher speeds. Between the roll bars there’s a reinforced glass screen which helps prevent blasts of cold air from the rear of the car.

Even on the motorway, it’s possible to have a conversation without shouting.
