RE: BMW Mulls Over Turbocharged V6

Forgetting our opinions, I find it hard to believe Merc failed to deliver when moving from I6's to V6's. And I've no doubt if BM go down the V6 route it will be an excellent engine and not just because of the advantages a V6 brings.Edited by Johnboy Mac on Monday 12th September 22:59

BMW, the last vestige of the straight six...
Apart from the other ones.The only other new car I can think of you can buy today with an I6 is a GTR.
Are there others? (I imagine there are lots of truck engines...)

<photo> proving CraigyMc couldn't be more wrong if he tried </photo>
Well, a 4am start is my excuse, and even if nobody else buys it, I'm sticking to it in my head (total confusion between GTR, and older GTRs.).
Is there another company doing i6's at all?
ETA: I think Aston were in the news not that long ago talking about going to them, and their slightly disasterous Le Mans car uses one...

I'll let you off!I was trying to think of other I6s and couldn't either. I used to have a Lexus IS200 which had a gutless but lovely sounding 2litre straight six. Only other recent one I can think of was the TVR engine. They certainly seem to be a dying breed.
Attempt at redemption: Volvo also does i6 engines, but as far as I can tell, not for the UK. The Volvo USA website does have them on (for example) the XC90.

Good Spot, Well worthy of redemption!Linkie: http://www.volvocars.com/us/all-cars/volvo-xc90/de...

If I remember rightly those are transverse as well. Surely the only front wheel drive I6 in the world!

Ford in Australia.
Cummins diesel engines in Dodge pickups.
I'm pretty sure GM do a petrol I6 in some stuff. Although wiki tells me they stopped them in 2009.
Not the GTR though

I had a whizz in a Merc twin turbo 3.2 V6, some years ago, and if BMW can match that, we'd all be mightily impressed. It was an AMG lump in what appeared, at first to be a dreary E220, until you saw the wheels,-about 12" wide. It was shatteringly fast, with both anchors and handling world class. At £44K I had to say,'I'll think about it' but if YOU get the chance of a joyride, take it, you will be amazed. Seems that BM have indeed applied for both V6 and V8 patents, several years after Merc showed 'em the way.
Which v6 was that?CraigyMc said:

Volvo have had transverse inline sixes since 1998, one family of them in the first generation S80 (and XC90s), another in the second generation S80, current V70, XC60, S60 and V60. The first lot were 2.9 NA and 2.8 twin turbo and were the old longitudinal engines adapted for transverse installation (which is why they made do with a crap four speed autobox when the rest of the range had a much nicer and more reliable 5 speed auto), the second generation were 3.2 NA (dropped from the UK range two model years back, along with the Yamaha 4.4 V8) and 3.0 twin turbo. The current Volvo I6 is 1mm shorter than its contemporary five pots(the Volvo/Porsche designed modular family, not the Ford derived ones).Linkie: http://www.volvocars.com/us/all-cars/volvo-xc90/de...

The layout above could theoretically also be a flat 6 - which matches an inline six in terms of inherent engine balance, V6s of 60 or 90 degree inter-bank angles do not and require balance shafts to compensate for these effects, which adds weight, complexity and draws power, reducing efficiency.
I'd rather BMW switched from inline sixes to V6s than to drop six cylinder engines completely. Now that the NA inline six is all but history, I find myself caring not a great deal with what they replace it, although the prevalence of fours and forced induction is a shame, but also entirely understandable with the constraints placed upon manufacturers.

Not the GTR though
I'm sure that Nissan and BMW will have the same packaging considerations on their minds whilst they think about a switch from a straight 6 to a V configuration, albeit not relating to AWD for BMW (I pray!)

A V6 has the same number of cylinders as a straight 6!
Not all sixes are created equal. Vs, inline, flats and VRs all have their own feel, sound and characteristics. For instance V12s are as smooth as they are because they run as two inline sixes sharing a crank, rather than two V6s end on end.

Worldwide, BMW build more all wheel drive cars than rear wheel drive ones and have for a few years now. Edited by Zwoelf on Tuesday 13th September 13:08

Outside of the UK, BMW already do 4wd for most of their cars, certainly in rhd format.C
