EcoBoost engine by ateixeira

When is this thing due? It looks promising...
 
http://blogs.edmunds.com/straightline/2008/08/fords-35-ecoboost-v6.html
 
Looks like it'll go in several Fords, I wonder if Mazda will get one for the CX9 as well?
 
$700 for 340hp sounds good, and it even runs on regular octane. The timing may be bad, though.
 
Also, I'm sort of more anxious to see what they could do to a smaller, more fuel efficient engine. Perhaps start with the new 2.5l used in the Escape. That makes about 175hp now, with twin turbos it could beat the Escape's own V6.

The Explorer America concept had, according to Ford, a 2.0L EcoBoost motor in it that put out 275 HP and 285 ft-lbs of torque. FE is improved 20-30 percent over the current 4.0L V6 in the Explorer.
 
Supposedly a 2.5L EB puts power output over 300HP but I've never seen anything "official" about that.
 
Click here to see the info about the 2.0L EB.
 
Oh, and the first one, the 3.5L V6, goes in the Lincoln MKS sometime next year. I think in the Spring. Anyone? No word on what will get the first I4 or when but they recently announced that they are accelerating those plans.

GM has had an Ecoboost being sold now, out for 2 years now, the 2.0L 4 cylinder, turbocharged, direct injection and variable valve timing engine. Direct Injection, Ecoboostlike click here The current GM engine gets 260 HP and 260 ft-lbs, two of the same numbers, similar to the 3.0L Freestyle V6, whose two numbers are about equal at 203 HP and 207 ft-lbs from a high fuel economy, no turbo, no direct injection engine. You can see how an even lower displacement Ecoboost engine could get the Freestyle HP/torque numbers. Also note the Mazda CX-7 is currently sold with direct injection, turbo, and variable valve timing, another Ecoboost look-alike. Ford's future take on this might have some mild innovation, but the tech has basically been out there a while now. VW and Audi are some more that have used direct injection, turbo, VVT. The key is to downsize the displacement so it just barely performs good enough, increasing MPG in the process.
 
Really the Ecoboost strategy is to put a 4-cylinder Ecoboost producing just over 200 HP, which a 1.8L size would do, in a place of a V6 in the Escape and Edge, and the next Ford Explorer, and it should get about 20/30 city/highway EPA rating with "just adequate" power.

rav4 or nissan rogue? by tigerlily3

I was about to lease a base 4x4 rav4 and then I went and test drove the base model nissan rogue. I thought the rogue's interior was far superior and it the ride felt fine (i didn't go too far or fast). I read some reviews about the rogue's CMT which deterred me from considering it. What are your thoughts? (the price is the same)
thanks!

Concepts are a bit different, for instance that one makes 275hp/2.0l so a very high strung 137.5 hp/liter specific displacement.
 
The production 3.5l Ecoboost makes a down-to-earth 97 hp/liter.
 
I think an EcoBoosted 2.5l would make more sense, making perhaps 240-250hp or so.

Is that the engine in the Cobalt? Do you know if that runs on regular fuel, or is it premium only?
 
The Mazda CX-7 ran on premium the first year it came out, but then Mazda tuned the engine to run on 87 octane, with no loss in power output (at least stated).
 
If Eco means Economy, then I think it's important to tune those engines to burn 87 octane.
 
Of course Eco could refer to Ecology, in which case emissions are more important than the type of fuel it burns.
 
VW requires premium fuel.
 
Not many turbos are tuned for 87 ocante.
 
I agree with your just good enough theory when it comes to the performance.

CVT, you mean, for Continuosly Variable Transmission.
 
Car & Driver raves about Nissan's CVT, calling it the best in the business. I've only driven an Altima but I'd have to agree - it was seamless and always seemed to choose an optimal ratio.
 
Having said that, other CVTs I didn't like as much, for instance the one in the Mitsu Outlander 2.4 CVT felt very disconnect, unresponsive.
 
It will take some getting used to, with no shifts, plus the RAV4 has an unremarkable 4EAT automatic. Purely based on the powertrain, I think I'd actually pick the Nissan, but...
 
The RAV4 is bigger inside, so you get more space for your money. I find the Rogue a bit small, and visibility is just about the worst in its class. The cargo area is just about the smallest as well. That may still be enough to meet your needs, but I found the Rogue made too many compromises for style.
 
Drive them both, pay particular attention to the Rogue's tachometer, to see what it does in different circumstances. My guess is you will either love it (optimized ratios) or hate it (odd feel, droning at steady rpms).

sorry CVT (i'm clearly not a car person!) . I drove the 6cyl rav4 this morning which has gotten good reviews. The reviews that I read on the CVT said it's great in a 6cyl but not in a 4cyl. Maybe I should get the 6cyl rav4 and live with the budget feeling interior.

The 4 cylinder RAV4 has a 4 speed auto, but the V6 model gets a better 5 speed automatic.
 
Since the V6 only gives up about 1 mpg, I'd actually recommend that engine. You'll be happy to have the extra power when you have a full load.
 
The Rogue's CVT doesn't use fixed ratios, so some even say it has infinite ratios. In truth it varies over a range, from a minimum to a maximum overdrive ratio.
 
In order of performance, I'd say it's RAV4 V6 1st, then Rogue, then RAV4 4 cyl.

Right. I'm assuming that concept version was maxed out give or take several horses. Since this one might go in the Fusion, Escape, etc. I'd bet it will be de-tuned to around 230-250 HP which is what the new updated 3.0L DT makes.
