I'm definitely interested in picking up this car when it comes out. But I can't decide weather to shell out the extra money for the turbo version. I'm hoping you guys can help me decide.

Now that would be a very nice add-on.

...that 215 cid V8-engine used 10.25:1 compression ratio and produced 215 hp, or 1.0 hp-per-cid.
...our 1.4L (83 cid) I4-engine uses 9.5:1 compression ratio and produces 138 hp, or 1.66 hp-per-cid!
...I'd say that GM technology has progressed "a little" over the past 49 years.

Hmm, by about 66%?
Imagine what could have been done with 215 cu and a turbo and some electronics.

A lot more power.

138hp for a turbo I4 @ 1.4L is not that great. With a retune it could pick up loads of torque and a hefty power gain. Don't know if it'll be #'s like the GTI reflash but I'm sure the map GM used is very conservative. I'm personally more impressed with GMs moves towards DI and DOHC larger displacement motors like their V6 Camaro with the DI version of my LY7. Although Who could ever turn down a 350? So easy to make power it's stupid.

...in a world facing $4-$5-per-gallon gasoline, fuel economy (MPG), not horsepower (HP), will too soon become paramount.
...what *I'd* like to see is a sub-1.0L engine producing 150 HP (that's about 10X what's needed to drive 55-60 mph) with a fuel consumption number pushing 100 MPG.
...that shouldn't be too hard to accomplish using turbo-charging, direct-injection and variable-valve lift/duration technologies--all which are available TODAY.

Motorcycle engines are hitting those #'s with the addition of nitrous
I may be wrong but isn't Honda the only one still offering variable duration and lift? I'm pretty sure Toyota no longer does VVTL-i and I'm confident the big 3 don't offer it as well. I can't think of any European companies that do it either.

Sweet I'll have to read up on it. I wonder if we'll see it crossover to Chrysler vehicles. Did you ever read that article in Popular Mechanics about variable displacement motors(not cylinder shut down but more of variable compression ratio)? Seemed interesting I can't remember what company was working on it though

Many people have a different opinion than you.
