BMW is looking to build on the success of its 7-series range in the corporate sector with the launch of two new ultra-luxurious versions.

Called the Exclusive Edition and available only on the diesel-engined 730d and long-wheelbase 730Ld versions, the models come with a selection of bespoke options which are not available on the rest of the 7-series line-up.

Sales of the range have rocketed by 56% in the corporate sector – with diesel versions accounting for three quarters of sales – and the recently-launched long wheelbase 730Ld is attracting strong interest from the chauffeur market.

The Exclusive Edition is set apart from its standard stablemates by the availability of various interior and exterior colour combinations and unique 19-inch alloy wheels.

Inside there is the option of Night Vision for better visibility while driving in the dark, active cruise control and adaptive headlights. Priced from £56,335 to £58,935, the Exclusive Editions carry a premium of £500 over the standard versions.

Elsewhere on the stand, the awesome M6 Convertible made its world debut. The 507bhp, 5.0-litre V10 flagship accelerates from 0-62mph in just 4.8 seconds and could, were it not electronically limited to 155mph, rocket to nearly 200mph. However, with CO2 emissions of 366g/km and a pricetag of £86,400, it’s not likely to be a huge hit with fleet buyers.
