so for now its a wait and see game for us.. infairness to mitsu. im pretty sure.. they will up the ante with for the 10... they pretty much now that their niche for evo owneres is more on the performance side.. hence evo is a performace sedan... im pretty sure they now what they are doing. and + 1 taumax about F1 kind of tranny going to the car..
for as long as mitsu makes its right i would for sure buy a ten.. if not my bro will..

I agree... Let's wait and see how it performs.
I for one, believe that switching to an aluminum block is a good thing.

Well, I don't think it's too much to expect flat wiper blades and an integrated antenna and GDI when something like the mazdaspeed3 has it all.

It's not like MITSUBISHI would have develope GDI from scratch... They've already put a GDI engine into production outside of NA.

All I'm saying is that it would be a shame if they didn't put GDI on the new EVO.
It's the trend for all small displacement high specific output engines.
Audi A3
Golf GTI
Pontiace GXP

GDI is largely a still unproven technology in terms of performance. THEORETICALLY it could increase power by cooling the intake charge (decreasing knock / increasing CR) and getting rid of the throttle plate. All actual reports I've seen (like the GDI Mitsu Charisma) have shown that this technology does not currently work well for either emissions nor performance because controlling the "tumble" of the fuel mixture prior to and during burn, which controls the flame front and knock, is an exceedingly difficult thing to do accurately. Audi and Mitsu have spent a lot of money on the "tumble" effect for over a decade and have shown no actual noticeable improvement in fuel efficiency nor performance. Both VW/Audi and Mitsu claimed these benefits. Both failed to as of yet show real world results. The FSI VW engine does not show good fuel economy numbers (higher real world than claimed), and when you look at power/liter it is hardly impressive. BTW GDI isn't new, it was tried in the 30s (a time which I still claim to be the apex of engineering design) but abandoned because of the technology limitations at the time.
I would classify current performance GDI engines as bleeding edge... nice for a R8 racecar, not so nice (for now) for your driveway. I highly doubt the Evo will have it.

Well all i can say is i dont like what they done to the new evo but it is called evolution and maybe the X will kick a** when it starts to show what it's made off, they must have something up there sleves..but who knows!

I wouldn't say that GDI is an unproven technology, it has just taken a long time to mature and bring to the mainstream.
AUDI, BMW, MAZDA, FORD, GM, MITSUBISHI, TOYOTA, HONDA all have production GDI engines.
More cars: BMW 335i, Lexus IS 350, Audi S6, Audi S8.
GDI doesn't mean you can get rid of the throttle plate. You can only get rid of the throttle plate if you have actuated valves.
On the contrary, GDI is good for power and emissions because you can control the amount of fuel injected more precisely than a port fuel injected car. A better mix of fuel and air can be achieved by adding intake port tumblers and fuel can be injected many times after the valve has closed.

In the thirties, they didn't the processing power required nor state of the art injectors.
I believe that the time is right for Turbocharged GDI engines for the mainstream.

I hope the EVO X has it.

All nice cars... if you like 14 second and sub-100 mph time slips.

The current 4G63 is a truely capable engine, however it is out dated. I want to see the potential of the new one before passing judgments. The Nissan SR20DET is all Aluminum and it's capable of making 1000 hp.
One thing I hate about the new EVO is the interior. Man I hate the intergrated stereo. Why can't they put a DVD/Navagation system there.

My comments were solely about the PERFORMANCE claims of GDI, I think I clearly stated that. European cars have GDI for emissions and fuel economy purposes. I was simply noting that Audi/VW has made LOTS of fuel economy claims about their tumble effect technology, none of which have yielded a car with REAL improved fuel economy. GM has made similar claims with variable displacement. It's all gimmicks that sell cars. When GDI allows for a motor that can produce more than 150 hp / liter I'll start paying attention.
