Also see previous winners. The same companies seem to dominate...

I am somewhat surprised by this....while the V10 is one hell of a motor, it is not particularly special innovation wise. The V10 foregoes the Valvetronic and opted for regular valvetrain and throttle body. It does not feature direct injection, and it does not use the magnesium alloy block like some other newer BMW I-6s....

IMO either the new BMW I6s or even Audi's FSI 4.2 liter V8 found in the RS4 may be a more interesting winner....

Im still wondering why the Audi RS4's engine isnt on that list.

At least when it comes to performance, it's what you have and not how you got it. In BMW's V10 you don't see a lot of their latest innovations, but you get a 5 litre V10 capable of 8,250 RPM with 80% of max torque available at 3,500 RPM. The Hp/torque graph show a very linear and steep power curve and pretty much flat torque curve, very desirable characteristics.

The RS4 is undoubtedly a stout motor, but working with 0.8 litres less, it's just outclassed in performance. Even with all the technology, there's no "replacement for displacement".

RS4 power chart: http://www.rri.se/popup/performanceg...p?ChartsID=281

Actually, very similar power delivery in both, just the V10 is a step above...

because it's not good enough? why else?

[matek]

Hmmmm well i think its an amzing engine seeing as this year we have no new rotary engine from Mazda

valvetronic is bad for high end performance which is what the v10 is striving to attain, if that engine had valvetronic it's output would be severely below that of what it has now

direct injection doesnt really improve power by a significant amount, fuel economy is the main reason to use it ... not really a concern for the cars the v10 is going into

a magnesium block, wow i've never heard of this but it sounds interesting, magnesium is really light but it isnt the strongest of metals out there, and small micrscopic fissures in a block could lead to dissasterous results ... wonder how they managed to do this ..

Well kind of
The problem with valvetronic is it uses moving surfaces with it's cam to alter the valve lift. So for an engien that's expected to rev out beyond 6000 it needs STRONGER valve spring to prevent bounce. This increase the friction in the movable surfaces of the Valvetronic system and leads to problems and wear.
So yeah, it's limited because they can't relly make Valvetronic rev out beyond 6000

How are points awarded?

• Best 1.4L – 1.8L: 1.5L Toyota Prius

oh come on . you are having a laugh. must be a bad year for moderately sized engines.

How are points awarded?

http://www.ukintpress.com/engineoftheyear/rules06.html

In every category, the panelists judged each shortlisted engine using their subjective driving impressions and technical knowledge, and took into account characteristics such as fuel economy, noise, smoothness, performance and driveability. The jurors each had 25 points to spend on their five favourite engines in each class. The maximum points that could be allocated to one engine was restricted to 15, while the minimum reward was one mark. An engine could not be tied for the top slot.

A lot of it is subjective, it isn't just a number's contest...

I think there are some judges who are truly and haplessly in love with the Prius engine. The Prius has won in '04 and '05 as well.

[TheOne]

ahhh engine of the yr awards of UK, was gonna wonder why the LS7 wasn't there.

[hightower99]

Knife edge 2k1: BMW did not make the whole block out of magnesium. They make a small block that incorperates all the cooling channels and holds the pistons out of aluminium then to add strength to the block they wrap a magnesium case around that. All problems solved and a nice 10% decrease in weight.

Matra: BMW sells the Valvetronic on an engine that revs to 7000rpm. but certainly going higher than that is going to need some interesting solutions (I keep thinking of ducati's desmo system)

The quote re the 6000 was DIRECT from BMW
It's maybe been updated .

Ducati desmo is a nightmare.
VERY expensive for even the daily use bikes.
The race bikes last ONE RACE.
Yeap, the whole thing is NEW every race !!!!
AND most folks forget that the "success" Ducati has with the desmo engien in wordl superbieks was because they were allowed to run a 1000cc engien whilst everyeon else had to run 750cc. Even now that everyeon is on 1000cc Ducati are allowed to run freee, EVERYOEN else has s RESTRICTED INLET to limit the power. Ducati "win" because they are politically strong, not from the engineering !!!

Desmo doesnt' have variable valve timing and has NO springs so the valvetronic problems isnt' repeateable.
