Sleepers carry the mink inwards: The game with the inconspicuous PS-show has a long tradition. While Rolls-Royce stated the performance of its engines as "sufficient" until 1998, many owners of a Mercedes 300 SEL 6.3 renounced on the nameplate in the late 1960s to buffle unsuspecting motorists with rapid spurts. Today there are still some cars to choose which hide their power more or less successful. The M135i is among them...

I want to share some of my Head to Head experiences with the M135i on the German Autobahn.

BMW's and Porsche's extremely opposing yet powerful 6cyl high performance engine technologies in an accidental meeting on a German Autobahn.

Head to Head:
BMW M135i (Automatic): 2979 cc R6 turbo (N55B30)
Weight: 1515 kg / 3340 lb
Max output: 235 kW / 316 bhp
Weight to Power ratio: 10.76 lb/bhp
Max torque: 450 Nm
Sprint 0-62mph: 4.9 s
Top speed: 155 mph (limited)

Porsche 911 Carrera S (997/2) 6cyl flat engine
Weight: 1480 kg / 3263 lb
Max output: 283 kW / 380 bhp
Weight to Power ratio: 8.72 lb/bhp
Max torque: 420 Nm
Sprint 0-62 mph: 4.7 s
Top speed: 188 mph

So what? The power isn't all yet. AFAIK Mercedes is famous for ridiculously powerful engines with no remarkable chassis. Porsche is reported to win by handling:

I'd instantly choose a basic Cayman over M2.

But I doubt that people will consider both as competitors. One is a fast family car, while the other is a two seater sports car. Both are however rather desireable, and can attract a lot of envy from others.

I did.

I've got no family. Rear seats are a waste of space. And I do want a sports car. The reason why I mentioned both was they looked priced "head to head", minding that M2 is a cocky wheeled smartphone while Cayman would be "pretty much just a car" for the money, meeting my needs.

Oh yes, this is a really heavy reason why I'm not going after Cayman (that's besides it's price). Even my current car appears vulnerable to that.

Here comes another one:
BMW M performance line's vs the "real" M GmbH's powerful 6cyl high performance engine technologies... I need a M4 - so badly

Pretty much highlights the difference!

Why "DSC off", as a matter of interest??

Better throttle response for one thing

Throttle response is the same in Comfort Mode and DSC Off.

[Bee Pee]

throttle mapping yes agree.

Trust me, M135i JB4 400+bhp and 450+ lbft responds much better with DSC turned off !!! :-)

That's what I thought ... Or is this M135i tuned?

Not according to the specifications given below the video.

Some folk do drive with DSC turned off through choice.

Looks to me like an M4 convertible not a coupe.

Get a JB4 fitted and setup on your M135i - evens it up somewhat

Oh, I know that's the case, I just can't understand why ...especially on those roads :

I can reassure you The dials are just overlays and aren't functional in this special video. DSC was on all the time - on highways there really is no use in turning it off..

That's because 400+bhp and 450+ lbft has the ability to overcome all available traction and will spin up the wheels most of the time on most public road surfaces. DSC will limit the power and torque to levels that prevent that loss of traction

Maybe so but my car's chassis is well fettled incl Quaife LSD - helps traction a lot and even with TC off it grips and goes

You need a lot of power of horrible aerodynamics to have traction issues on the Autobahn. I remember I tested a 321hp Z3 M Coupe with studless winter tyres on wet roads. It did not have traction control, but I could still use wide open throttle in first gear without any wheelspin if I launched it carefully.

From physics, power equals force times velocity. At 200 km/t, with 500 hp at the wheels, you have around 6600 Newtons of thrust, which is less than 0.5 G of acceleration.

Reads like SteveC and Ovekvam are at opposite ends of the same pole !!!

I drive always dsc off. I prefer it this way. I notice big difference when i leave traction control on. Its just annoying.

How about DTC? This mode pretty much disables the traction control, but leaves the stability control on. I think it works well for driving on public roads in slippery conditions, but I also use DSC Off all the time when I am on a track.
