The G37x S is the latest addition to the Infiniti G Saloon line-up in the UK. It is the first time Infiniti’s sportiest S grade has been available with AWD in the G range. Previously only the GT was available with AWD.

Like all G models, the G37x S is powered by a 316bhp (320PS) 3.7-litre V6 mated to a 7-speed automatic transmission with paddle shifts – a combination that delivers 0-62mph acceleration in just 6.0 seconds.

The car has a top speed of 149mph and an official combined fuel consumption of 25.7mpg (11.0 l/100km) with CO2 emissions of 255g/km.

The newest G model costs from £38,979, like every G model sold in the UK, leather seat facings, Shodo aluminium trim, adaptive bi-Xenon lights, Scratch Shield paint, i-Key smart access, electrically adjustable front seats and steering column, and heated front seats are standard. The only option for any G model is metallic paint (£577).

Two GT models, both now in rear-wheel drive form only, make up the entry point to the range. The G37 GT costs from £34,909 while the GT Premium – with Multimedia pack and sunroof among its extras features – costs from £37,849 OTR.
