Mazda has expanded and improved its Mazda6 range as it attempts to gain a larger share of the business market.

A trio of new diesel engines headline the revamp – all 2.2-litre units offering power outputs of 125, 163 and 185bhp.

They replace the existing 2.0-litre unit.

The new engine offers combined fuel economy of between 49.6mpg and 51.4mpg, with CO2 emissions ranging from 147g/km to 152g/km, helping all but the highest-powered unit stay in the same company car tax bands as the out-going 2.0-litre.

Elsewhere, a new top-spec Sport Luxury trim level has been launched, complete with full leather interior, 18-inch alloy wheels and Bose stereo.

Mazda is also introducing a new blind spot warning system as standard on all models from TS2 grade upwards.

The device uses radars mounted in the rear bumper to monitor vehicles approaching from behind in the outside lane of a motorway or dual carriageway.

If the device senses a vehicle approaching it will illuminate warning lights at the base of the A pillar.

Mark Cameron, Mazda UK sales director, said: “With this revised line-up we anticipate growing our share of the business car segment next year.

“Compared to last year, the Mazda6 is already taking an increased share of the large family car segment, standing at 6% by the end of September.”

The revised range goes on sale in January.
