Comparison tests AutoBild - BMW M135i xDrive vs Mercedes-Benz A45 AMG

[DeDe]

2nd place: BMW M135i xDrive (236/300 points, 78,7%)
The BMW is the more civilized car in this comparison, it's less sporty but more comfortable.
(Also: official Launch Control-function in the M135i? This is news to me.)

• Weight: 1591 kg
• Weight distribution (front/rear): 54/46%
• 0-100 km/h: 4,9 s
• 0-200 km/h: 18,3 s
• Braking (100-0 km/h), warm: 34,4 m
• Contidrom laptime: 1:38.87 min

1st place: Mercedes-Benz A45 AMG (239/300 points, 79,7%)
The A45 goes very well and sounds like a racing car. It also corners better thanks to its sport-suspension. The downside: less comfort, higher price.

• Weight: 1573 kg
• Weight distribution (front/rear): 62/38%
• 0-100 km/h: 5,1 s
• 0-200 km/h: 17,1 s

• Contidrom laptime: 1:36.62 min
• Noise level @ 130 km/h: 72 dB(A)
• Average fuel consumption: 9,5 l/100 km

Scans: here.

(Also: official Launch Control-function in the M135i? This is news to me.)

Launch control has been standard on the ZF 8 auto box since the middle of 2013. My 335i has it, it's a hassle to engage and it doesn't really make much difference imo.

M135xi Weight distribution (front/rear): 54/46%

I find it interesting that the weight distribution for an M135i xdrive BMW is the same as the weight distribution for an Audi S4 quattro.

A45, 0-100 km/h: 5,1 s

How did they manage such a slow time?

 

[Mr. Mercedes]

Indeed that time for the A45 is pretty pathetic and off the pace.

 

[DeDe]

How did they manage such a slow time?

With Race Start... AMS also got 5,1 s. Maybe there's another methode for activating that function (AutoBild Sportscars and AutoZeitung managed 4,4 s).

Here's the proof that black is always the right color choice!
The A45 looks pretty cool here!
How did they manage to launch the A45 slower than the M135ix?

Bimmer is keeping up in the beginning but power advantage for the Benz is showing in the end. Probably change once a true M version is coming.

 

[Merc1]

LOL, the BMW was left from the first few secs off the line.

The video I saw the bimmer was right behind the benz but then suddenly the difference was more noticeable when they got on to speed. Every review between this shown that the benz is quicker. It's lighter and more powerful. Audi S3 also been quicker than M135i in various reviews.
