The 4.7-metre-long BMW i8, shown here at the Frankfurt motor show, features unusual construction methods, using a carbonfibre-reinforced plastic (CFRP) bodyshell sitting on a welded aluminium chassis.  BMW claims the i8 can hit 62mph from rest in just 4.4sec with both the engine and electric motor engaged. Top speed — achieved by the petrol engine alone — is 155mph. BMW says this performance is partly thanks to the i8's relatively low weight of 1490kg and an aerodynamic bodyshell, which has a drag coefficient of 0.26.

The 3-cylinder 1.5L turbo petrol engine that produces a remarkable 228bhp is a stand-out feature that is getting buried under the batteries and the near incredible 25g/km CO2 and the 113mpg from a car that hits 62 in under 4.5 seconds.
Imagine this engine in a 1-Series or Countryman. Pretty impressive stuff.

If you can extract that amount of horsepower from a 1.5 triple,is there really end need for engines with 6 cylinders......?

This is a game change car for BMW,in the sense that they have a car with performance to match most of BMW's opposition,top speed today is irrelevant,the daft mpg figure is just not attainable although if BMW and the like can prove it i'll believe it then,i think it's a great looking car,typical BMW interior,and i will repeat this,are we seeing the last death throws of large capacity Engines?,if you can get 220bhp out of a 3 cylinder,and 500bhp out of a 1.6 (Williams/Jaguar),it definately beggars the question.

    Is the third gen Citroën C3 ‘fresh and different’ enough to take on its supermini rivals? We spend six months with one to find out

    A satisfying rework of the X3 that usefully improves its handling, cabin finish, space and connectivity to make this BMW a class front-runner again

    Off-road estate is now bigger, more spacious and available with torque-vectoring all-wheel drive, but is it enough to make its German rivals anxious?
