Watch: BMW M3 Touring review, 2023's most wanted new car

At last, an M3 estate. The new BMW M3 Touring, an M3 with a big boot. You get the same 3.0-litre twin-turbo engine from the standard M3, but 500-litres of boot space for all your clobber. Could this be the perfect practical performance solution?

To find out, Top Gear magazine’s Ollie Kew put the new M3 wagon’s touring and dog-carrying abilities to the test with a 1,500-mile road trip... to Barryland. Prepare for big slobbery dogs. You have been warned.
