As expected Maruti is gearing up for the nano battle.

Stripped-down Alto to be priced at Rs 2-2.5 L - Express India

I hope this is only a short term plan and they come up with a new model to combat nano.

[JustCause]

I hope the 2cyl motor gives enough scope for Maruti to not to compromise on the level of kit offered & further strip down the already emaciated F8D Alto. Let the Nano buyer get almost equal or better features in this Maruti version. I also expect cut throat marketing by Maruti.

This may as well be crowned as the most fuel efficient Petrol car, ever made for India in India.

What I heard is: Maruti is stripping 1 cylinder from both the 1L and 1.2L K-Series engines and that makes the YP2 and YP3 engines. YP2 is a 2-cyl engine,and YP3 is a 3-cyl engine.

Similar to the 1086 and 796 cc engines of yesteryears right?

Why would they want to strip one cylinder from the 1.2L K-Series engine when they already have the same (read K10B)? I believe the YP3 would be a two cylinder unit by stripping one cylinder from the K10B.

The F8D & the F10D displace 796cc & 1061cc respectively (bore & stroke are the same so the reciprocating parts are shared between both engines).

Unlike the F8D & F10D where the bore & stroke dimensions were preserved across engines & the primary difference was in the number of cylinders, the K12M & K10B differ in stroke. If all they did was lopped off a cylinder from the K12M to get the K10B its displacement would've been 898cc (instead of 998cc). The K12M stroke is 71.5mm & the K10B stroke is 79.5mm.



If the YP3 is a 2-cylinder version of the K10B, its displacement would be 665cc.

@im_srini - Thank you for that enlightenment. I thought it was just one cylinder chopped off from the K12M. 2 cylinder 660 cc engine is what they could be targetting for the Cervo. Looks like a chopped K10B fits the bill perfectly.

I mentioned this impossibility of Maruti having two different 3-cyl K-series engines (900CC and 1000CC) to the guy who told me about this. What he says now is:

"What Maruti aims by these YP series engines is big cost cutting by lower number of cylinders and smaller royalty to Suzuki, so these engines don't seem to be developed from the K-series engines, but is from another Maruti engine. Seems, from Eeco's engine."

So mods, please delete my earlier post in this thread.
