Making power is easy, any manufacturer can do it. If they don't it's because they choose to pursue some other performance metric.

Those engines also cost more then any of the twins, have a team dedicated to keeping them alive for one race at a time then taking them all apart and making sure they don't break during the next race. No exactly the kind of thing alot of manufacturers like to warranty. I also doubt they get very close to the 30mpg+ we get.

I think I remember reading where it is possible to get 400hp from a 1.6L, but I good luck getting a company like Toyota giving you this with a 60-100K mile warranty?

Built right, it could last longer than VTech or an M motor. I think cost and fuel economy would be the larger concerns tbh.

Agreed. IF you want lag, there's plenty of other cars to buy. Especially from Subaru.

It would be interesting to see if this new engine acts as a step between the standard impreza and the wrx, 148hp vs 265hp.

I was thinking they would sell the 2.0 engine still but either offer a boosted 2.0 or 1.6 for an STI type version.

As far as modern turbos go, I recently owned a twin scroll 2.0T Gencoupe which made 274hp and 275ft lbs of torque. Throttle response was iffy.. It really depends when you punched it, but there could be noticeable delay sometimes. Nothing like previous turbos I had owned and driven, but still noticeable compared to a NA or supercharged engine.

I agree with you on supercharging. I personally would prefer a more linear buildup of hp/tq. The Gencoupe, for example made peak torque under 3000 rpm. And while it can be a blast sometimes, it also makes the car feel less predictable when you are in a turn and punch the gas.... You suddenly have max torque being pushed to your rear wheels...

They also said the 86 would weigh 2,500 lbs :shrug:

Mercedes is gatting 355 horsepower with a peak or should I say, a plateau of 332 lb-ft of torque from 2250 to 5000 rpm from a 2.0-liter engine in the CLA 45 AMG.

That's amazing...

FA20 develops 100hp/liter naturally aspirated.

A 1.6 liter making 240hp equals like 150ish hp/liter with boost. Doesn't seem to far fetched. There are other production cars that make more.

I don't think it would be 240hp though. It's achievable but it makes me question longevity and reliability coming from such a small motor.

Yes, but your taking about a car that starts just under $50K..

Ya, that motor is no joke , but then again.....all AMG motors are "handbuild"....+ I don't think Mercedes owners are gonna complain about reliability of their car pass 50k miles since they will be on the next one.

Those motors lasted 500-1,000 miles on a good day (some didn't make it through the first practice session, the M12 definitely had some reliability issues), this is something designed to last for (ideally) 200,000 miles. I didn't say impossible, just said that I doubt they could do it. I would think 220 is possible, 200 is more likely.

Actually, of all engines out there that subaru has and are developing, I see this one as the perfect, and most sensible, one for them to throw into the BRZ. Lots of cars these days offer a larger N/A and a smaller turbo engine as an option. I wouldn't be surprised if this did happen. Moreover, this would assist in keeping its fuel economy where they want it at.

I think this is a much likelier option than a hybrid system or a bigger NA motor.

That being said, if Toyota has anything to say about it, it probably won't see production. Especially considering their contract with Subaru regarding the twins.

Its exactly 150/liter, which is exactly what an Evo has (300hp/2 liter). I can't speak from experience about those motors but mitsubishi has been getting 270+ out of 2 liters for quite a while now. I don't think reliability would be an issue at 150/liter.

MMM have you heard of the M133DE20AL? I suggest you look that up.
