Despite BMW’s concerns that the ‘coupé’ moniker was putting off potential purchasers, sales are picking up. By the end of August, BMW had registered 14,257 4 Series models, of which 4,211 were Gran Coupé. Fleets accounted for 2,308 of those.

It’s a joy to drive; handling is sharp and assured, grip is excellent and the 190bhp engine has plenty of oomph. But it is just as comfortable pottering around urban environments, with the stop-start eager to cut in whenever traffic stops.

Drivers can flick between three driving modes via the Drive Performance Control button: sport, comfort and Eco Pro. BMW claims Eco Pro improves fuel efficiency by up to 20%; so far we’ve struggled to get much above 46mpg (52mpg on a long run).

The Route-Ahead Assistant uses the navigation system to assess local road conditions and give tips in advance. If there is a speed limit change around the next corner, the system advises the driver to slow down before turning.

However, the advice can get frustrating, particularly the harsh acceleration symbol. On a number of occasions, it has flashed on when the car is travelling well below the actual speed limit, for instance 45mph in a 60mph zone. It can be an annoying distraction.

The sat-nav deploys a useful traffic overview, colour-coding roads green, yellow or red depending on traffic. However, the system cannot seem to make its mind up. On a recent trip, the information about one section of the M25 changed no less than 12 times, with the journey time fluctuating between a one-minute delay and 64 minutes.

Technical niggles aside, as we move into our final month with the 4 Series Gran Coupé, the experience has been overwhelmingly positive. With the running costs a smidge under 46p per mile (matching the Audi A5 Sportback, but a couple of pence above the 3 Series saloon), this is a car to satisfy both fleet manager and company car driver.
