BMW M4 gets noisy (2013): listen to the new M4’s turbo straight-six here

  With the unveiling of the new BMW M4 imminent, BMW’s excitement has got the better of it with the M Division releasing a video showing featuring the new M4’s engine note. The video might be called ‘BMW M is preparing something new’, but the engine isn’t really a fresh design. It’s actually a tweaked, twin-turbo version of the 435i’s 3.0-litre straight-six, making this the first M Division 3-series derivative to use forced induction.

Mercedes A45 AMG: Official

The Mercedes A45 AMG – Mercedes’ first ’Hot Hatch’ – has been revealed ahead of a debut at Geneva 2013. It gets 355bhp and does 0-62mph in 4.6 seconds. The 2.0 litre turbo 4-cylinder engine under the bonnet of the A45 produces a very healthy 355bhp and 332lb/ft of torque, enough to scoot the A45 AMG to 62mph in 4.6 seconds yet still returns official economy of 34mpg.

BMW reveals ferocious new M3 and M4

IF YOU’RE no fan of Top Gear-style wheel-spinning, tyre-smoking oversteer, then it’s probably best to look away now, because BMW has unveiled the new M3 and M4. Essentially the same car underneath, the main differences come in the number of doors and the suspension settings, with the M3 built as a four-door, slightly more forgiving saloon and the M4 as a harder-edged two-door coupe. But both will go very sideways, if that’s the sort of thing that revs your engine, thanks to a shared 425bhp six-cylinder engine that sends all that juicy power to the rear wheels.
