Infiniti G Convertible engines, drive and performance
Looks are average and uninspiring but as soon as you press the accelerator pedal you’ll forget the bland design. The 320bhp engine allied to the seven-speed auto ‘box means you can, theoretically, complete the benchmark 0 to 62mph sprint in 6.2 seconds and go on to an electronically limited top speed of 155mph. That’s not too shabby for a convertible until you compare it to a Porsche Boxster that’ll get from zero to 62mph in 6.1 seconds.
Then when you consider that the Boxster S can do the benchmark sprint in 5.4 seconds you can see that the Infiniti is starting to lag behind the leaders in this sector. The great thing about the G 37’s V6 engine, though is that it has bundles of power right the way through the range and it sounds good too. It’s not really a bona fide driver’s car and most will opt for an auto box as a result.
If you are a real enthusiast that wants a bit of purism then you can go for a manual.
Predictably the Convertible loses some of the stiffness of the Coupe. The rear-wheel drive and the front-mounted engine gives the car a decent level of front-end grip while the steering is well-weighted. However, corner at speed and you won’t get the grip levels offered by the Coupe. The chassis rattles and flexes at motorway speed which does not inspire a lot of confidence.
Rivals including the BMW Z4, Mercedes-Benz SLK and Porsche Boxster are better equipped for those drivers looking for pure enjoyment. The G 37 Convertible is a decent motorway car but it’s not suited to B-roads because it just feels too wallowy.
