2015 Mustang is now confirmed to be getting a turbo 4 cylinder model, good for up to 300HP possibly.

Only question now is whether it will be a European-only model or also for the US (and rest of the world).

There's conflicting reports:

Interesting but, in the current overly large incarnation of the Mustang chassis, how much weight could they save with a 2.3L turbo 4? The Boss weighs 3,632 lbs according to Autoguide. The Coyote V8 is only about 430 lbs. Could an engine swap save more than 100 lbs? Smaller tires, wheels, and brakes, another 50 lbs? Weight distribution would be better. But I can't believe a 4% weight reduction would make much difference in handling or feel.

2015 is a new platform. *Supposed* to be lighter-weight. And IRS

Cool but the only stang I would ever be interested in is a v8.

A mustang with a 2.3 turbo... Hmmm, sounds familiar.

I'm not sure they are putting in the 4 cyl to save weight, rather than to be able to sell more Mustangs in Europe where V6 and V8 models are expensive due to their engine size.

Yeah I can see the logic for the European market. I was just hoping they might resurrect the SVT concept as well. Could be a fun car.

Here's hoping it comes with an IRS with no weight gain. It's already the lightest muscle car, and in the realm of the M3, so if it can add IRS and no weight gain, oh man with a V8, sounds like may need to start rolling up the pennies. Good thing though is that it cant take that much of a price hike considering its competition, so 30k for a 430hp rwd irs coupe, hmmmm.

The idea that IRS adds a lot of weight is a bit of a myth, fuelled by the IRS Mustang Cobra's +150 lb. weight gain. But most if not all of that additional weight was due to making a "bolt-in" IRS setup for a car designed around a live-axle, with massive cradle/subframe to beam the loads from the IRS suspension hard points out to where the solid axle hard points were on the car.

The myth was reinforced mightily with the gigantic and massive 5th-gen Camaro coming in at 3800+ lb. vs. ~3400 for the 4th-gen live-axle car.

A car designed from the get-go for IRS will not be that much heavier vs. a car specifically designed to be live-axle. We're talking tens of pounds difference, not 150-400 lb.

The 2015 is *supposed* to be lighter-weight than the current 3600+ pig. We shall see...
