Infiniti G Coupe (09 on) - Review Review by David Ross on 09 February 2010 Last Updated: 16 December 2010 Infiniti is the upmarket brand of Nissan - in a similar way that Toyota has Lexus - and the G Coupe is the most sports-focussed model in the range. It's designed to be a high-quality alternative to models such as the Audi A5 and BMW 3-Series Coupe with supreme build quality and top-class refinement. It certainly feels like a luxury car on the move with superb refinement while it's also enjoyable to drive with impressive handling. The fact that Infiniti is quite unknown means the G Coupe is a rare sight on the road and attracts attention, although the styling isn't particularly daring or distinctive. The biggest drawback is the limited engine line-up - there's currently only one petrol - a 3.7-litre V6 which is thirsty. The interior also lacks the style and sophistication of alternatives, while the rear seats are cramped. However, Infiniti dealers, although few and far between, do offer the highest levels of customer service. 3.5 out of 5 Other Infiniti reviews Summary Facts & Figures Equipment Driving & Performance Comfort Costs Safety & Reliability Buying & Selling Also Consider Company Car Info Gallery 2.5 out of 5 Running costs While the G Coupe is well equipped as standard, it's not very cheap to run with a thirsty V6 engine and expensive road tax. Insurance is costly too with all versions in group 45 (in the newer rating from 1-50) which is the equivalent of group 19 in the old system. And while Infiniti dealers offer superb levels of customer care that would make even Lexus owners slightly jealous, it's not cheap by any means. Expect service rates and parts to be expensive, and likely to be on a par with Porsche. Summary Running Costs Servicing period Every two years/20,000 miles. Warranty Three years/60,000 miles.

It averages just 27mpg while CO2 emissions are high at 248g/km (246g/km with the automatic) - hardly environmentally-friendly.
