Mercedes B-Class gets a facelift for 2015 – debuts at Paris Motor Show

The Mercedes B-Class facelift goes on sale today (12 Sep 2014) from £22,575 It seems only five minutes since the second generation Mercedes B-Class arrived, but it’s getting a bit of a facelift – with the emphasis on the ‘bit’ – for 2015, with the main focus being the arrival for the UK of the B-Class Electric Drive which, for many considering an EV from a premium maker, is perhaps a better option than the ‘statement’ BMW i3. Tesla had a big input on the B-Class ED’s electric gubbins, and the result is an electric B-Class that develops 177bhp (and 251lb/ft of torque), enough for a scoot to 62mph in 7.9 seconds (top speed is limited to 100mph). Range, in an ideal world, is 124 miles from the 16.6kWh lithium ion batteries – enough for most commutes.

This quick video of the “long tail” hybrid testing at Monza gives us a preview of what we can expect at Spa next month -- and hints at what we'll see at Le Mans in June.
