Autocar's Steve Cropley has been given exclusive access to the Infiniti M saloon during its development at Nissan's Cranfield Technical Centre in Bedfordshire.
The new M saloon will launch in September in the UK and will be one the first Infiniti models to be powered by the firm's V6 diesel engine. In a class featuring capable diesel rivals from Mercedes, BMW and Jaguar, Infiniti needs this 3.0-litre single-turbo diesel unit if it stands a chance of competing with its established rivals.
Cropley's drive was in the M30d variant which will make up two thirds of sales; a 3.7-litre V6 petrol unit, badged M37, will make up the rest of the sales and will launch in October.
The test car's black anti-photography stripes meant appreciation of its design would have to wait for another day, although Cropley described the interior as "cocoon-like and beautifully made". The M will track the BMW 5-series closely on price, although it will come with more generous levels of standard equipment.
