New BMW X5 M and X6 M

Well, they did. BMW decided what they really needed to do was stick the M nameplate and performance bits on many of their X-series SUVs. We're living in hard times, like you need me say so, or if you need further proof, then look no further.

Seriously BMW, is that what you decided to do? Don't do something like make an M version of that little disposable Series 1 you had to play with SUVs. OK, okay... what's the problem?

Alright, what's so special? Why shouldn't I look down on these latest SUV iterations?

"...the 555 hp twin-turbo V8 engine heralds the launch of the most powerful M road car ever launched by the company."

Ah! OK, that might improve some of my animosity, but not really. Still, triple-nickel power makes up for a bunch of other flaws. To be more specific, when inserted into the X5 or X6, said twin-turbo chopper produces numbers like this:

555hp at 6000rpm, 680Nm of torque at 1500rpm, zero - 62mph 4.7 seconds and a top speed of 155 MPH (unfortunately this is electronically limited).

OK, those are pretty impressive numbers. Hard to dispute that.

Here is an interesting and somewhat disturbing piece of information about the architecture of the engine:

"...the turbochargers and catalytic converter are located in the V of the power plant. This arrangement results in an engine that breathes better and runs with higher output due to the shorter outlet manifold. It also results better packaging as the unit is more compact.”

Yes, it's true. It's all true, but it still worries me. Why? Thermal loading, that's why.

Ferrari tried the same packaging solution with its F1 cars at the dawn of the turbo age. Designed for a neat little power unit; small, easy to drop off, all logical reasons mentioned by BMW. Turns out it was a reliability, maintenance and thermal nightmare. The heat buildup between the cylinders was just too much. Various alloys would warp and bend under loading...and plumbing? Don't even ask. Yes, on the upside, the turbo lag was basically gone, and that was a good thing.

Who knows, maybe BMW fixed those issues, and maybe it's not that big of a deal in a road car (you know, more room and all that), but only time will tell. will say. But it still worries me.

The two new M-badged Xs have new trannies. Dubbed the M Sport automatic transmission, it features an electronic management system that has been fine-tuned to meet the sporting demands of the vehicles. It comes with three selectable modes, a Drive mode, a Sports mode and a Manual mode that the driver can choose from depending on their mood and the road and traffic conditions. There's also Dynamic Performance Control on both vehicles, which is a new style of differential, which diverts power to the drive wheels rather than braking the spinning wheel.

There are also electronic damping controls, head-up displays, Dynamic Stability Control settings, a Servotronic steering system, an M Drive Manager (a menu system that allows the driver to tailor the characteristics of the car ) and more bells, whistles, flashing lights and technology than Werner von Braun could handle.< /p>

The new BMW X5 M and X6 M will soon be available in showrooms and suburbs.
