BMW is launching an estate version of the M5, and for the first time in the model’s history it will be sold in the UK and in right-hand drive. The Touring arrives in British showrooms this May priced at £67,075.

Mechanically the M5 Touring is largely the same as the saloon (500bhp V10, seven-speed paddle-shift, M differential). However, the rear suspension is modified with self-levelling air springs, while extra strengthening has gone into the flat boot floor to increase rigidity.

The claimed 0-62mph time is 4.8sec, just 0.1sec slower than the saloon, while all-round performance is said to be on a par.

Meanwhile there have been a raft of improvements to the 5-series range as a whole, including engines updated with BMW’s High-Precision Injection system, tweaks to the six-speed auto ’box, a subtle facelift and higher quality interior fittings.
