I had a loaner 118i a few weeks ago. Doesnt sound like an exciting badge but I was surprised how well it went for "just a 1.8 engine". Then looked on the website and realised its 170bhp and 0-62 in 7.4s. And its not a 1.8, its a turbo charged 1.6.
The 114i has just 102bhp which must feel quite pedestrian.
