Seven awards for four engines

The BMW winners:

BMW 3.0 litre Twin Turbo in-line six cylinder petrol engine

BMW M 5.0 litre V10 petrol engine

BMW 2.5 litre in-line six cylinder petrol engine

MINI 1.6 litre Turbo petrol engine

With seven awards for four engines, BMW once again emerges as the most successful brand from the “International Engine of the Year Awards 2007”, the world’s most important engine competition. For the third time in a row, the Awards jury – consisting of 62 high-ranking international automobile journalists from 30 countries including Australia – awarded the principal prize, the highly sought-after “International Engine of the Year” to the Bavarian automobile manufacturer.

This year the trophy goes to the new BMW 3.0 litre Twin Turbo petrol engine, now fitted in all body variations of the successful BMW 3 Series. The world’s first in-line 6-cylinder engine with Twin Turbo technology also came out top in two other categories, winning the “Best New Engine of the Year 2007” and the 2.5 – 3.0 litre capacity class.

In addition to the engine’s enormous pulling power, the jury was particularly impressed by the high efficiency of the 225 kW power unit. With 9.5 litres per 100 kilometres in the BMW 335i Coupé, the average fuel consumption level based on the EU norm is extremely moderate for this performance class. The Twin Turbo achieves this mainly due to BMW High Precision Injection, the first jet-guided direct injection system ever to be produced in high-volume production. It enables a particularly precise metering of the air-fuel mixture.

Two awards were won by the V10 high-performance engine, which is to be found under the bonnet of the BMW M5 and M6. The 507bhp power package with a capacity of 5 litres received the award “Best Performance Engine of the Year” as in the last two years, and also won in the engine class over 4.0 litres capacity. In 2005 and 2006 this exceptional engine won the “International Engine of the Year” award itself. “The BMW V10 is still unsurpassed”, said jury member Jeroen Jongeneel of “De Telegraaf”.

The 2.0 – 2.5 litre Award was won by the 2.5 litre 6-cylinder petrol engine with VALVETRONIC which is used in the BMW Z4 Roadster 2.5si and X3 2.5si. With its fully variable valve control – used for the first time in 2001 and since established in millions of vehicles – the engine delivers 160 kW and founds the BMW philosophy of efficient dynamics. “You can hear the 2.5-litre engine from a long way off due to its exquisite sound”, says jury member Rogelio Rivera-Nava from Mexico. “The in-line 6-cylinder construction provides the basis for the technical purity of this most famous of all BMW engines. It is pleasure to drive it.”

And this was not the end of the prize series for BMW Group. In the 1.4-1.8 litre category the trophy jointly went to BMW Group and PSA Peugeot Citroën, the developing partners of the 1.6 litre turbo engine. It powers the MINI Cooper S with sporty 128 kW, as well as models of the developing partner in brand-specific adaption. The newly created special features of this 4-cylinder engine include the innovative Twin Scroll turbo technology and a fuel direct injection.

Over the last nine years, BMW has won over 30 of the highly sought-after “International Engine of the Year Award” trophies. This is impressive evidence of the BMW’s market leadership in the field of engine construction.

If only Nissan has kept developing its RB series straight six engines....add magnesium/aluminium crankcase, Direct Injection and variable valve timing...would have been a winning formula for the RB.

[D3RV]

thanks for that, an enjoyable read

[Spunky Munky]

Breath-taking but I am fan of the RB engine. Let us not forget the fierce power of the RB series.

RB25DE - twin-cam 140 kW/190 PS and 147 kW/200 PS (with VCT) @ 6000 rpm, 255 N·m (26.0 kgf·m) @ 4000 rpm)

RB25DET - twin-cam turbo (245 to 250 hp and 319 N·m)

NEO RB25DET - twin-cam turbo (206 kW (280 PS) @ 6400 rpm, 362 N·m (37.0 kgf·m) @ 3200 rpm)

RB25DE and DET engines produced from August 1993 also featured NVCS (Nissan Variable Cam System) for the intake cam. This gave the new RB25DE more power and torque at lower rpm than the previous model.

Hang on worlds first am I missing something here nice mill sure but hardly the worlds first

think my 89 vintage rb26dett might a been there first, not sure there isnt others too

spot on. :sorcerer:

[Risking]

In comparrision all of the RB series engines are shit house in both design and function.

Nissan would not have had a hope in hell even with development against these engines.

These engines are far smoother, and nicer to use than enything nissan could ever have come out with in the RB series. You cant compete with the direct injection system and its something that almost every manufacturer has struggled to get off the ground with and particularly nissan. Hats off to BMW who have successfully launched the system.

Nissans flagship engine is obviously the VQ35 and VQ40 which is tonnes better than the RB engines from a D & F perspective. Even these dont rate in the international engine awards because they are far to harsh and not nearly refined enough to compete.

Or was it Toyotas 1GGTE 2ltr twin turbo 6cyl found in the early model Soarers??

[kralster]

I think the mean first cos it uses varible geometry turbo's. You know the ones they use in the new 997 porsche turbo and big trucks.

[T04GTR]

yeah. they work well but are ineficant and under engineered.

All I can say is... Think about how much these BMWs cost, and then think back as to how much our beloved skylines cost!??!

they are in two different leagues!!

And mate, give me a RB any day of the week!!!

[342Four]

wasnt the old toyota 7M-GTE twin turbo

the old 1GGTE was indeed twin turbo six, but i thought the 7M was b4 that

[_8OO5TED_]

7M-GTE was the 3ltr single turbo engine, famous for blowing head gaskets

Actually, I just had a look, it was APril 1989 that the that the Soarer became available with the 1GGTE engine.

[paulr33]

as u sure this gets "twin turbo" classification? i would call this a bi-turbo setup as you have two turbochargers of different sizes

one small, one big. well marketing call it twin turbo, but to me twin implies to turbo's of the same size

Thanks for scretching my itch mate - fucck yeah!

It's like comparing a double-storey brick villa to a wooden shack. LOL

But yeah, honest to God and may I be punished if should I sin. I would choose a R33 GT-R with mods as opposed to a BMW any day, any second of the week. I am madly in love with Skylines, screw the Hitler cars!

But they always come in the Top 10. The new HR variant has made it 13 years in a row for the block.

Its not variable geometry. Look at the pics - they've got wastegates. VGT turbos don't have wastegates - the boost control is done with the vanes inside.

I dont know if you are talkin about the 1GGTE but it has 2 turbos the same size...the 1 and 2jz use different sizes but the 1GG doesnt.

Cheers.

I dont know about the 7M.

actually, that's incorrect.. the VQ35DE was voted in Wards top 10 engine list from 2002-2007. They are a world leading engine..

The VQ35DE is built in Iwaki, Japan and Decherd, TN. It was on the Ward's 10 Best Engines list for 2002 through 2007. The Nissan VQ engine is the only engine to have been present on the list every year since the competition’s inception in 1995.

[342Four]

most car mags and stuff most often say that the rb26 is one of the only true twin turbo (6) engines

like oblivion said, both the 1jay and 2jay were twin sequential turbo, the 1GGTE was only a 2litre twin with a pissy 150kw at the rear wheels (from what i remember) and the rotaries (despite not being a six, but a twin) were sequential aswell

i wouldnt mind one of those 5litre v10's tho

theres a vid floating around with a m5 with a full stainless german engineered exhaust that sound like a bloody f1 car (and, its in america - no suprises there...)
