BMW Performance Models.

 

“For the times they are a-changin” … the immortal words sung by Bob Dylan back in 1963 were meant more as a social (societal) comment, but that phrase could be used for nearly any decade since Dylan penned them.

Today’s automotive manufacturers concentrate on safe, clean, and green vehicles, and it’s almost frowned upon to talk of such vulgarities as performance, speed, and enough power to stick any rear passengers to the rear window. But occasionally, a mainstream manufacturer bucks that trend and delivers something a little special.

BMW is one such mainstream manufacturer.

BMW M3 and M4 Performance Models

Of course, the BMW M3 has been around for a lifetime – 35 years to be precise, whereas the M4 is still relatively youthful, at just eight-years-old, but within that timeframe (certainly in the M3s lifetime), attitudes have changed somewhat.

You’ll notice that for the main part, dealers, manufacturers, advertising, and marketing people are wary of concentrating on pure performance – they might tell you that a car has 500+ horsepower, but they’ll off-set that by adding something about its green credentials … “Yes, the latest performance model has 555 horsepower, but thanks to clever engine management strategies, it will still achieve 55 mpg”, or something like that.

We have to say that it never ceases to amaze us just how performance engineers can squeeze so much power from an engine, and still be so much better for the environment than just a few years ago, but occasionally there’s just no getting away from POWERRRRRRRRR (as one J Clarkson may say).

And that brings us to the raison d'être of the M3 and M4.

BMW Performance

Just this once, we’re taking a leaf out of BMWs book and talking about all things performance, so forgive us for our temporary madness, normal service will be resumed shortly.

The M3 and M4 have never been criticised for lack of performance, but BMW have gone to great lengths to improve upon the predecessor regardless, which means the UK versions will have over 500 horsepower from the twin-turbocharged straight-six engine, although the rest of the world will be offered a slightly lower tune option.

The increase in power equates to around 50hp and 73 lb/ft of torque, although peak torque is slightly higher up the rev range. BMW have achieved the increase with a number of upgrades – redesigned turbochargers, a slight increase in stroke length (to 90mm), and a heavily revised fuel-injection system.

What this means is that the M3 makes 299 horsepower per tonne, and the slightly lighter M4 makes 300 horsepower per tonne, figures which would have been unheard of just a few years ago. Regular top speed is limited to ‘just’ 155mph, but there is an option to upgrade the car, giving a top speed of 180mph (still electronically limited), just in case you really need that extra.

More Than an Engine

It’s not just the powertrain engineers that get to have fun either – the new M3 and M4 have benefitted from a number of upgrades – a wider track, improved suspension, slight increase in overall size, and … this will make some people very happy … their own front-end style.

For the first time ever, BMW are also giving the option for fully variable M xDrive four-wheel drive system, which is capable of diverting the power infinitely between the wheels, and finally, there have been a number of aero changes to improve airflow and dynamic efficiency, these include a multi-channel rear diffuser, and two rails running the length of the carbon fibre reinforced roof to better direct airflow.

The BMW M3 and M4 are all about performance, yes, they look pretty incredible in their own right, they do make for a great ‘regular’ car, and of course you won’t have to make sacrifices over comfort and practicality, but it’s performance engineering that they’re fast becoming legendary for, and for that, just this once, we’re happy to go along with BMW.

If you’d like to experience the performance for yourself, or just have some questions about these, or any of the other BMW models, then get in touch with one of our friendly team, and they’ll help in whatever way possible.
