Alpina changed the performance figures:
Torque: 700 Nm / 1500 rpm
0-100 kph: 5,1 s
Vmax.: 275 kph

Please fix the torque figure - it's official: 700 Nm / 1500-3000 rpm.

Also: 0-200 km/h in 20,3 s (factory's claim according to AutoBild Sportscars 02/2012)

Official figures:
350 hp (257 kW) / 4000 rpm
700 Nm / 1500-3000 rpm

Assuming a similar torque curve to the 535d, it will be about 730Nm at 1750 rpm. Alpina have changed some of the components (and software) in the gearbox so I presume the torque is higher than any other car using this box. It must also be near the limit of even Alpina's rear wheel drive because the BMW 50d tri turbo engine is being targeted at 4 wheel drive only I hear.

You can calculate the torque at 4200RPM. HP is a function of Torque, so yes, you can calculate the NM at 4200 RPM. 437 LB-FT TQ @ 4200 RPM.

Torque (LB-FT) * Engine RPM (at which the TQ is produced) / 5250 = Horsepower (at the RPM the Torque variable is produced).

Figure it out for yourselves.

I only read the comment directly before my own, and it has no mention of units. Pretty simple really.

Bottom line: The torque will be plentiful.


User avatar

annoying  6y ago

it's obvious that I was talking in metric units, especially since I said the torque at 4200rpm was 585nm.


User avatar

Apathy  6y ago

I know peak torque would be at a lower rpm.

My comment was in response to your "614@4000" statement.
I thought you meant 614 lb/ft.I now realize you meant Nm.
Perhaps you could include units in the future? :P

"The engine should only produce 460lbft of torque at 4000rpms. Is there a link that mentions the car's torque rating? "

Apathy, figure at 4k rpm is 453 lb/ft, but this however is not it's top figure, because then the engine would be too peaky, for a normal turbo diesel power curve torque should be around 700nm (516lb ft) at under 2k rpm .

The engine should only produce 460lbft of torque at 4000rpms. Is there a link that mentions the car's torque rating?

Of course they could limit the torque, but the fact is that it has 614@4000, and that's about 16% more than 535d...


User avatar

FastestLaps  6y ago

He is guesstimating. This engine could just as well have no peak torque improvement compared to 535d at all, if Aplina decided not to increase boost pressure at lower rpm range to ease the stress on tranny or whatever else.

Interesting.


User avatar

Annoying  6y ago

I can calculate torque from this engines figures. And i can guess that if it has 614@4000, it should Have over 700 max. The other engine is for a reference.


User avatar

DeDe  6y ago

How can you calculate torque from another engines figures? We don't even know the boost-differences for instance.


User avatar

Annoying  6y ago

There's 614nm@4000!!


User avatar

AnnoIng  6y ago

I just said that there's 585nm@4200. If it's based on 535d which has 500nm@4400, and 630@1600, this one could Have even more Than 700. (730?!)


User avatar

DeDe  6y ago

At 4200 rpm is its max power: 350 hp. The torque figure will be between 650 and 680 Nm in my opinion.


User avatar

Annoying  6y ago

There's 585nm@4200, so Probably over 700?
