The 1 Series hatchback had a choice of seven engines. Since 2006 all came with six-speed manual transmission as standard, although earlier versions of the 116i and 118i had five-speed gearboxes.

The petrol powered models were both swift and refined for the time, although the 1.6-litre petrol needed to be worked hard to get the best from it. In March 2009 this was replaced by a 2.0-litre engine (already used in the 118i and 120i) but with power at 122bhp.

Thanks to more pulling power this was less strained and acceleration times were slightly quicker too. The range topper was the 265bhp 130i – it’s as quick and responsive as you’d expect while the lightweight six-cylinder engine sounds glorious as it revs up to its 7000rpm red line, however it was phased out in 2007.

It was the diesels – 118d, 120d and the later 123d and 116d – which were most impressive.

Most of the engines were upgraded in May 2007 with improvements in performance, perhaps the most notable being the 118d where power was upped from 122bhp to 143bhp.

This engine was the pick of the range thanks to its blend of strong performance, superb economy and cheap road tax. All three diesel models in the 1 Series actually used the same 2.0-litre engine – but in different outputs.

However thanks to two turbochargers the 123d has an output of 204bhp. This gave it hot hatch-like performance with a 0-62mph time of just 6.9 seconds while in-gear acceleration was even more impressive. This didn’t come at the expense of economy though as it still returned a claimed 54mpg.

The 116d – launched in March 2009 – returned a very impressive 64mpg but still managed 0-62mph in a respectable 10.2 seconds.

The rear-wheel-drive 1 Series didn’t disappoint on the road and was as much a driver’s car as larger BMWs. It’s well-balanced, corners precisely and has good body control plus the steering is excellent too – well weighted in corners, with good feedback.

There’s plenty of grip, even in the wet and a sophisticated rear suspension set-up means that ride comfort was excellent over all surfaces, even with the harder than normal run-flat tyres fitted.

The M Sport models carry over the same mechanical upgrades as the Sport models (lower, stiffer suspension) but with various styling enhancements and ‘M’ branding. On the 130i the M Sport model has 18-inch wheels and wider, narrower section tyres at the rear as well as the styling kit. You certainly feel the road more but the pay-off is an even higher level of grip and a more focused feel to the car when pressing on.

Active steering was available as an option on 130i models for better precision at high speeds and less effort at lower speeds, but it received a mixed reception at the time and shouldn’t be considered a deal-breaker.
