You know what would rock...
 

...a 2dr Yaris with a Metro XFI engine and tranny in it!!

I really like the way those little Yaris's look, but the millage doesn't seem so great according to the fed website. If one could stuff the guts of a Metro into the shell of a Yaris, that would be really awesome!

Anyway, I know it's not possible, but just thought I'd dream out loud.

Better yet... take the above dream car and convert it to Nat Gas!! Not sure if you lose mpg with the conversion, but if not, that'd be sweet. 2+ bucks a gallon for NG at 50+ mpgs. That'd rock!

It's definitely possible, :p

Find one with a blown engine and do it!

I'd prolly just have a custom tranny with HF like gearing made

Hate to be a downer, but a swap like that wouldn't be smog legal. Atleast in any CARB states, the engine has to be the same year or newer....

That would be nice, but would the XFi engine and tranny even be capable of pulling the Yaris out of its tracks?

Yaris is a fine car. The numbers from the gov only tell part of the tale. It's not unheard of to get mpgs into the 40s. Only reason I didn't get the Yaris was because 2006 was its inaugural year and I wanted something with a little more space so I settled for the xA.

OK, 50+ mpg may be a stretch but with some massive modding and smarter driving, it is still in the realm of possibilities.

Hello,

The Yaris 2-door hatchback with manual transmission is the highest MPG non-hybrid car sold at the moment. EPA Highway is 41, IIANM -- my xA's current EPA Highway is just 34mpg. I'll bet the Yaris would be pretty easy to get to 50mpg.

Neil - FYI, the EPA currently shows the smart fortwo as the highest non-hybrid highway mileage (41) - Most and Least Fuel Efficient Cars

Yaris is listed as 36 hwy for the manual transmission.

Given that the smart is burdoned with an automagic, you'll be lucky to get 41. As for the yaris w/ stick, you'll easily do 25 - 50% more than 36.

yaris with a metro motor .. SLOW as heck.. but it may work , after all i saw a 10 hp diesel ina metro and it did 50mpg.. but a yais is 1200 lbs more than d the 1800 lbs metro..

However yes EPA on a Yaris 5speed is 36mpg, however, I bet you can pull 43-45 from it with hypermiling, I get 35mpg in my chevy colorado pickup its rated 25 mpg..

Definitely a handicap, yup.

Though the (not necessarily accurate) "MPG Estimates from Drivers Like You" portion of fueleconomy.gov shows 9 fortwo owners reporting an average of 37.7 combined, and the car has a 36 mpg combined rating.

Back to the OP's topic... a 49 hp motor in the Yaris would work fine. It'd have a worse power to weight ratio than the original 40 hp diesel smart fortwo though, which got to 100 km/h in somewhere around 20 seconds.

I could live with that. (But I'm used to sub 20 hp peak power in the 2070 lb ForkenSwift).

Who lives in carb states? :p

I'd stick a 1.2 TDI 3L from across the pond in there. It got the Audi A2 over 80 mpg easily.

I agree, if you talk about using a different engine, you have to go with one of the TDI versions. Can't beat that mileage.

In the "For Sale" section on InsightCentral, there's a complete Insight power train offered by a guy that swapped a bigger engine into his. Even if you just went with the IC engine instead of the full hybrid, I don't think you'll find too many engines that'll give you better FE.

If you can get 50.14 mpg for a tank from an Aveo , and you can, then I'm willing to bet you can beat that with a Yaris by a respectable margin (stock), and I personally would like to try. In fact it's kind of a secret ambition of mine, I like the Yaris, but right now the Aveo's what I got to work with.

The bigger question in some circles, namely, my racing buddies "can the metro pull itself out of it's own tracks?" LOL

Seriously, I was talking about this whole 'engine swap' idea with a friend the other day. Seems it's just impracticle foe most pepole to pull off these days. When I was 16, I shoehorned a 400cc engine into a 250cc bike. At 17, I squeezed a 327cu in Chevy into the engine bay of a '71 Chevy Vega. But those were carburated vehicles, when the Vega had very modest smog equipment requirements. These days, a TDI or VW Lupo engined Miata would make a fun little sportscar, a metro engine and trans in just about anything would be great. But the computer controls add a whole new dimension and level of complexity to such a project. Then you have the state emissions test to get by every other year in California...

It's too bad, because these days, young guys (and gals) have real limited oportunities to learn while working on their cars.

I'd rather an insight with a 1.2 TDI under the bonnet

just fyi folks... this was more of a hypothetical situation (concept car kind of thing). i wasn't actually suggesting it could really work - though from some of your posts it sounds like it might actually be possible!

the wish, really, was to combine what i think are the killer looks of the yaris with the fuel economy of the geo xFI. sort of a concept car kind of thing. hehehehehe.

would be nice though eh? for tiny little cars, i really do think the Yaris is the best looking thing out there at the moment. slap some OEM (again, if they made them) wheel skirts on the thing... pull 50+ mpg's without any major mods or driving techniques, such as is the case with the xFI's... that would be super awesome.

at any rate, hopefully someone will start coming out with a new version of the 3cyl now that gas is through the roof. perhaps a Geo "2.0" can save GM from collapse!!! LOL

I doubt there will be anything like a Geo 2.0, they're too busy betting on the Volt.

Or even better than a Yaris with a Metro engine, one with an electric motor!
ELECTRIC YARIS

The problem with this swap is it is incorrect assumption that the reason the Metro gets better mileage than the Yaris is its engine. The real reason is the Metro weighs 645 pounds LESS! The Yaris weighs 39% more than the Metro. :eek: I bet that if you looked at the specific fuel consumption of the 2 engines for a given output the Yaris engine is probably more efficient than the Metro. If you compare them on a hp/L basis the Metro makes 48.7 while the Yaris makes 158.6. If the Yaris engine were reduced in size to match the Metro output it would be 460 ccs!

(I know the output wouldn't be linear. Hey I'm just having some fun here.)

;) :)
