A series of videos on Youtube show the highlights of an event organized by BMW for motoring journalists to test out the new engine mounted on a BMW 1 series.

Quoting from the Bavarian manufacturer - "In addition to the high-revving characteristics and gratifying responsiveness, the emotional sound of the engine also makes an important contribution to the driving experience. Because the frequency of the sound of a three-cylinder engine increases 50 per cent faster than that of a four-cylinder, the engine is perceived as being extremely vivacious and sporty."
Codenamed B38, the unit fitted into the prototype 1 series is tuned to produce 180bhp and 270Nm of torque. It is connected to an 8-speed automatic transmission in the test car. This new engine family will be offered in outputs ranging from 120bhp to 220bhp eventually. They can be mounted longitudinally or transversely and therefore will be suitable for application in front-wheel drive, rear-wheel drive or all-wheel drive vehicles.
BMW claims that the new three-cylinder engine sounds similar to a six-cylinder instead of a four-cylinder. Is the claim justified? Switch on your speakers to find out!
