Sitting at the top of the tree, the BMW 135i is currently the fastest and most powerful
The beauty of the 135i is that it offers all the practicality of the standard 1 Series, with the added firepower of a turbocharged 3.0-litre straight-six.
All models are rear-wheel drive, helping make it one of the finest handling hatchbacks

With its amazing engine at the heart of its appeal, the 135i is a joy to drive.
The silky-smooth six-cylinder revs all the way to 7,000rpm and has a sweetly tuned exhaust note. It’s quick, too – 62mph arrives in just 5.5 seconds
