Nissan 350Z — MPG & Fuel Costs 2025

Nissan's muscular V6 sports coupe, offering classic rear-wheel-drive handling and a glorious exhaust note.

The Nissan 350Z resurrected Nissan's Z-car legacy, featuring a front-engined, rear-wheel-drive layout and a naturally aspirated 3.5-litre V6 engine.

It was highly popular in the UK for its raw, old-school sports car feel and affordable price tag, though it is a relatively heavy vehicle with high tax rates.

Fuel economy is poor, with the V6 averaging around 21 MPG in mixed driving. Careful motorway cruising can return a maximum of 28 MPG.
