F10 BMW M5 vs. BMW M550d. Is it a fair comparison or simply an apple to oranges approach? German magazine AutoBild is on a mission to find out if the M550d, BMW’s first tri-turbo diesel, is a better product than the “pure M5”.

Earlier this year BMW unveiled their first M-tuned diesels powered by an all-new tri-turbo engine that develops 381 horsepower and 740 Nm (546 lb-ft) of torque. Along with the impressive performance, the M550d Sedan offers fuel economy figures of 6.3 liters per 100 kilometers in the EU test cycle.

Part of the M Performance Automobiles family, the M550d uses a series of M-touched technology: M-tuned suspension, bodyshell mounting, engine and transmission mounting, springs and dampers, all standard and optional chassis control systems, and the Servotronic mapping for the hydraulic steering.

Compared to the M550d, the M5 is what someone may call a pure M machine. Powered by a newly developed high-revving V8 engine with M TwinPower Turbo (consisting of Twin Scroll Twin Turbo technology), the M5 brings to the super sedan market 560 horsepower and peak torque of 680 Newton meters (502 lb-ft) between 1,500 and 5,750 rpm.

So power aside and straight line from 0 to 60 mph, which one is a more well-rounded vehicle?

AutoBild places the M550d xDrive ahead of the M5 with a total of 512 points vs. 495. Here are some of the stats:

1st place: BMW M550d xDrive (512/700 points)

Weight: 2040 kg
0-100 km/h: 5,2 s
0-160 km/h: 12,0 s
Braking (100-0 km/h), warm: 35,6 m
Noise at 130 km/h: 69 dB(A)
Average fuel consumption: 9,2 l / 100 km

2nd place: BMW M5 (495/700 points)

Weight: 1950 kg
0-100 km/h: 4,4 s
0-160 km/h: 8,6 s
Braking (100-0 km/h), warm: 33,9 m
Noise at 130 km/h: 72 dB(A)
Average fuel consumption: 11,6 l / 100 km

The diesel M won because of its comfort and fine-tuning: great balance between sportiness and everyday usability. Less costs. The M5 is a first-class sport saloon.

    To me, that’s a bit of a silly conclusion coming from an auto mag. If they chose it on comfort alone, why would they even include a pure M? I’m not sure what they’re trying to achieve with this non-sence conclusion, other than to point out what outstanding vehicles both are and just how accurately BMW engineered bothe to do what their buyers want.

    M5 > M5d for sport, but everyday driving M5d > 550i.

  3. Driving a well performed diesel is fun. I personally have a 330d e93, i love it in the city and especially when i hit the autobahn i can go up to 270km/h. The new 3turbo diesel engines are amazing with performance, but i think they need to come up with something more than 381hp. Otherwise what is the point of buying a diesel m5 when you can buy a 535d which cheaper and fast as hell.

    My verdict is: If you need performance, handling, loud exhaust sound, then get an M5. If you looking for something in between then get a 535i or 535d or even a 550i. But an m550d i think is stupid to buy.

  4. Mateo says:

    i hate both of them. m5 has engine sound from speakers……….that’s enough! if someone wants everyday car with good performaces M550d, i someone wants enjoy – any previous M5

  5. Guest says:

    I haven’t personally even seen either one, but based on reviews, it seems the 550d is a very capable fast autobahn cruiser rather than an all-rounder. I’m not 100% sure what that translates into for us in the US. We can’t really drive all that fast on highways, so maybe the M5 is better for our relatively cheap gas and ex-urban commutes. I guess the question is moot anyway because the 550d isn’t available here.

  6. J says:

    Put 560HK in the M550d and it will murder the M5 even more

    Forever M5!

  8. mckillio says:

    Give the M550d a V8 diesel and there would be no contest.

    A tri-turbo pathetic engine. All it can is to run 0-100 kmh in 5.2 seconds. The A6 3.0TDI does the same in 4.9 seconds having much less hp. Another testimony to Audi’s superiority over the crappy bmw.
