Chris Harris video: M135i vs A45 AMG

That BMW meets much tougher competition from Merc's A45 AMG - can it still prevail?

Can the world handle another M135i story? Judging by the multiple pages generated by PH doing nothing more than outlining the specification of the new fleet example, the answer is yes.

On the 4 Series launch earlier this week I met both the man responsible for the M135i powertrain, and the chassis - two rather talented individuals I hope you'll agree. They both talked of the car with real passion and the chassis man let slip that BMW is considering a mechanical locking differential for the car - it would be the first option I'd tick.

A45 can't do this - but does that really matter?

I really would like to drive a very basic specification M135i. I'm pretty sure that all I would have now is the gearbox, some heated seats, the adaptive dampers and a method of connecting my iPod and phone to the car. The rest I'd leave.

The A45 AMG is better specified - I've already written something about the car but the video gives you the chance to hear those pops 'n bangs.

One thing that shines through in this test is just how perfect rear-wheel drive is for the internet video generation. Ignoring the pros and cons of rear drive in the UK, you just can't argue with how much more exciting it makes cars appear on video and in magazines. I wonder how much this influences BMW's decision to remain RWD? I wonder how many cars are sold on the back of an oversteer photograph or video clip?

On the road the A45 is a very exciting car, but because it doesn't move around as much, won't lay down black lines and make people like me whoop on a track it comes across as being a little sterile. That simply isn't the case.

The German ultra-hatch is a fast emerging genre. It's a recipe that works especially well on UK roads.

Why no RS3? It would have been slaughtered.

Enjoy the vid.
