The Infiniti M became the Q70 in the spring of 2014 and received a subtle facelift to match its new identity. But only now has Infiniti reappraised its prices and substituted the slow-selling 3.0-litre diesel version for this more fuel-efficient four-cylinder diesel, which uses the same 168bhp 2.1-litre Daimler engine that you’ll find in the Q50.

The four-pot diesel repositions the Q70 in the heart of the mid-sized executive class, making it much more competitive on price and CO2 emissions with the biggest-selling versions of its German rivals.

I'm a sucker for Infiniti's flowing, wavy design language, and it works better on a five-metre saloon than anywhere else.

Emitting less than 130g/km of CO2 and now available, quite well equipped, for less than £33k, the Q70 suddenly looks like a justifiable prospect for the company car drivers who make up the overwhelming majority of the class’s clientele. The Q70’s 2015-model-year facelift brought about an exterior redesign that’s more noticeable on Sport versions than our Premium Tech test car.

Nevertheless, the keen-eyed will have clocked new LED headlights and tail-lights, new front and rear bumper designs, a new ‘wave mesh’ radiator grille and a smattering of extra chrome, none of which appeared on the old M30d.

This is an elegant-looking car, partly thanks to its generous overall length. Distinctive compared with the straight-laced German norm, it’s certainly a charmer.

Under the skin, besides accommodating the new diesel engine, Infiniti’s engineers have better sealed the cabin, retuned the suspension for better rolling comfort and fitted new alloy wheels for a quieter ride.

Customers who don’t want the new Daimler diesel option are offered as an alternative Infiniti’s petrol-electric Sport Hybrid, which partners a 298bhp 3.5-litre V6 petrol engine with a 67bhp electric motor.

Emitting 145g/km, it qualifies for company car tax only 1 percent higher than the diesel. Then there’s the range-topping 316bhp 3.7-litre V6 petrol, which gets sports suspension and four-wheel steering. Other markets than ours are also offered four-wheel drive and long-wheelbase versions.
