BMW’s 3.0-litre twin-turbocharged diesel engine is now available in the marque’s flagship model range. The new BMW 740d comes powered by a 306hp six-cylinder engine capable of propelling the vehicle from zero to 62mph in 6.3 seconds before going on to an electronically-limited 155mph top speed. Such performance also appeals to the financially minded courtesy of a combined consumption figure of 40.9mpg and CO2 emissions of just 181g/km.

The BMW 740d is available in standard-wheelbase only with specification highlights including glass sunroof, lane departure warning system, speed limit display and lumbar support for driver and front passenger. The BMW 740d is on sale now priced from £60,265 OTR.

BMW 730d and 730Ld enhanced as M Sport specification comes to 7 Series range

The most fuel efficient and cleanest conventionally powered luxury car has reinforced its green credentials with the introduction of a revised engine. The new BMW 730d and 730Ld now come with a 3.0-litre six-cylinder diesel engine that features enhancements to the fuelling system for greater efficiency.

The BMW 730d now returns 41.5mpg on the combined cycle compared to 39.2mpg while the BMW 730Ld records 40.9mpg against 38.7mpg. CO2 emissions also improve with the 730d dropping from 192g/km to 178g/km and the 730Ld now recording 180g/km opposed to 194g/km. These statistics mean both models drop to VED band ‘I’ and are thus cheaper to tax. The vehicles also qualify for a lower benefit-in-kind rating (26 per cent and 27 per cent) representing an even more compelling proposition for the business user.

The latest BMW 730d goes on sale in September from £53,695 OTR with the 730Ld costing £56,755 OTR.

Revisions to the most popular derivative of 7 Series come as M Sport specification is available on the model for the first time in its 32-year history. M Sport is offered on every incarnation of 7 Series and comprises M Aerodynamic body styling, 19-inch M light alloy wheels with the option to upgrade to differently styled 20-inch alloy wheels, Dynamic Drive and High-gloss Shadowline exterior trim. Inside, and Sport seats, M Sport steering wheel, door sill finishers with M designation and Anthracite headlining are standard.

Prices for M Sport models start with a BMW 730d M Sport at £58,750 OTR rising to the BMW 760Li M Sport at £96,590 OTR.
