The headline stats are that Alpina has squeezed 345bhp from the BMW 3.0-litre twin-turbo diesel. This equates to a top speed of 168mph and 0-62mph in 5.2secs.

Perhaps more impressive, however, is the fact that Alpina has managed to do so while maintain the same fuel economy rating (45.6mpg) as the 241bhp 530d.

Performance and economy :cool:

Agreed. When dropping 70K on a car, economy should be a bonus not a necessity.

That's precisely the case here though, the headline figure is that they've got 345BHP, the bonus being that they've done so whilst getting a fuel economy figure equivalent to a 241BHP 30d engine.

They've hardly made the economy the focus of anything, just Pistonheads stating it's impressive given the power output they've made :confused:

They've not gone out and marketed this as an ecocar or anything, I don't understand the reaction of 'what's the point' really.

There'll be a lot of point once 5 years of depreciation has kicked in.

If you can find one to buy, plus by this point the economy will take a back seat to reliability and ever increasing warranty costs :p

It's a stunning car but the B5 is just as stunning and has a far nicer powerplant.
 
Do Alpina, being effectively a small volume car maker, have to put their cars through the same EU tests/etc as BMW do for there models?
 
Look around at all of the performance upgrades / large power hikes you can get for turbocharged petrol engines & you have your answer - most petrols are normally aspirated.

There is no possible way that a car that gives 100hp more in tuned form has the same economy as the standard one.
There is absolutely zero chance of a 345hp car giving >45mpg is there :).

Being fair, that's clearly not true.
Alpina are not simply allowed to hit the random key on a Casio calculator to determine the fuel economy.
What they're saying is that in the standard tests that all cars run through, it's just as economical.

Now of course back in the real world, go out an use that performance fully, and you're right, it'll get nowhere near that, but then you could say the same of most cars. The typical level appears to be that real world figures are a good third lower than their "combined" fuel test figures.

I am not saying you are wrong, I just find it hard to understand how a tuner gets 43% more power than what a class leader in efficient engines (BMW) can get.

It is just too good to be true, unless when tickling the throttle the map is the same as BMW's was.
