The updated Infiniti Q70 will start from £32,650, an £8,000 reduction on the outgoing model, thanks to a new 2.2-litre diesel engine.

The upgraded line-up, on sale across Europe from January, starts with a new Q70 2.2d model, powered by a four-cylinder diesel engine developed as part of Infiniti’s cooperation with Daimler.

Mated to a standard seven-speed automatic transmission with available paddleshift (depending on model), the new 2.2 diesel unit in the Q70 emits just 129g/km of CO2 while offering stirring performance thanks to 170PS and a generous 400NM of torque.

Replacing the 3.0-litre V6 diesel in the Q70 range, the new Q70 Premium 2.2d is priced from £32,650. The car comes as standard with full LED headlights, chromed accents on the front grille, a rear-view camera, front and rear parking sensors, with standard Connectiviti+ navigation,  18-inch wheels and leather seats with ventilation, in what is a typically generous  Infiniti standard specification.

The current 3.0-litre diesel model starts from £40,025, with 199g/km CO2, so the brand is hoping the improvements will make the range more fleet friendly.

As well as the new 2.2 diesel engine, the Q70 for 2015 is available with both 3.7-litre V6 petrol power and, for the flagship, the award-winning Infiniti Direct Response Hybrid powertrain. Benefitting from the enhancements introduced on the Q50S Hybrid, the latest Q70 Hybrid offers even more performance – accelerating from 0-62mph in just 5.3s – and better efficiency, with CO2 emissions at 145g/km.

The new Q70 will arrive in the Infiniti network from  January 2015.
