    The long and short of it is this.... you will not have to rev these Ecoboosts to move them. They are not even high reving engines... both making their peak horsepower 500rpm lower than the Corvette V8.

    BTW... this is mathematically impossible.

    .... the fail here... it makes my head hurt. Horsepower is a marketing tool and nothing more. Torque is what moves you. More torque at a lower RPM is a good thing. Horsepower is a measurement of torque over time (rpm).... There is no need to spin these engines up because the torque comes on low. HP = (torque X RPM) / 5252 For the 2.3, that means at 3000 RPM where the engine is making its most torque, the engine is making 171 horsepower. For the 2.0, that means at 3000 RPM where the engine is making its most torque, the engine is making 154 horsepower. For the 4.3, that means at 3900 RPM where the engine is making its most torque, the engine is making 226 horsepower... BUT you have to spin it up an extra 900 RPM to get that HP.... At 3,000 rpm however, the 4.3 V6 only makes about 270 lb-ft meaning the horsepower output at that speed is about 154 horsepower. At 3,000 rpm, the 4.3 V6 produces equal horsepower to a 2.0 Ecoboost and less horsepower than the 2.3 Ecoboost. You're not after peak horsepower... you're after peak torque.. and you want it as low as possible on the Tach. BTW, the Tesla Model S makes its maximum torque of 315 lb-ft at ZERO rpm (software limited). No matter what the torque is, at ZERO RPM the horsepower is ZERO..... but 315 ft-lbs @ ZERO RPM (impossible in any internal combustion engine btw) will rip your eyelids out when you let off the brake.

    And just like with FWD, Mercedes finally gets with the program 40 years late.

    the HF 3.0 was never a particularly compelling engine... if they did do a 3.0, it would/should be a new design.
  6. Drew Dowdell
    Get Mark.

    These aren't high reving engines. Look at the RPM the torque peak comes in at... 3,000 rpm for both. To put that in perspective, the new Ecotec 4.3 liter V6 in the Silverado makes its peak 305 lb-ft at 3,900 rpm while the 5.3 makes its peak torque at 4,100 rpm. The old 3.0 liter V6 in the Lacrosse actually had to be revved way more than either of these Ecoboost engines. It made 255hp @ 6900 RPM and 217 lb-ft @ 5100 RPM and nary a turbo in sight! Even our 1.4T in the Encore rarely crests 3,200 rpm in daily driving while the 2.4 liter CR-V regularly needs to tickle 4,000.

    They do need the S40 back. They are trying to make the S60 the base model, but the price is just too high for a base Volvo. They need a Verano sized car starting around $27k.

    With Lutz gone and Akerson on the way out... who will be left at GM to make the PR team squirm?!

    I bet SMK will expect Cadillac to chase Mercedes here on volume and then wag his finger when Cadillac's sales numbers aren't as high.
  11. Drew Dowdell
    If the mustang loses weight, that's probably a good base engine.

    Just spoke to someone in the know. We'll get information on the date/venue for Canyon after the official Colorado reveal.
  13. Drew Dowdell
    2 tone paint like that needs to make a comeback.
  14. Drew Dowdell
    Yeah. My guess is that, if the rumour has some truth in it, it'll be a variant of the 3.6L block but I guess with a smaller bore. I think the rationale is that a smaller displacement engine using the 3.6L block would have thicker cylinder walls and it would withstand higher boost pressures. Smaller bore would make sense too. I seem to remember that the HF engines were capable of taking cylinder sleeves to adjust bore size, so the block itself would actually be the same but then they could sleeve it down to the displacement they wanted it to be. With no sleeve, the displacement would be 4.0 liters, but it would have to be a relatively slow, all torque/no rev, engine.

    Did he pull the motor or just cover it?
  16. Drew Dowdell
    hmm... that's actually better than I expected.
  17. Drew Dowdell
    I would probably rather one of these than the CR-V
  18. Drew Dowdell
    well the new 5.3 is the same in name only..
  19. Drew Dowdell
    The Avalanche fell in sales because after the second generation, their pricing was way out of line. They are just a body style variant of the Suburban and Tahoe... it's additional cost to GM was minimal and then they would sell another 25k - 30k trucks. In contrast, there is a huge expense GM is incurring in selling just 3,000 Chevrolet SS here. I have nothing against the car and I look forward to driving it... but the idea that the SS is a viable business case in the US and the Avalanche is not doesn't pass the sniff test. I would like to see an Avalanche like variant of the Colorado as well..... having the mid-gate type of feature in both medium and large sizes would be a unique offering in the truck market.

    I've never experienced AFM issues.... I'm not saying they aren't there, but I've never noticed them to be sluggish. I have a Silverado 1500 coming as a review car next month, so I'll get another look.
  21. Drew Dowdell
    I doubt this would be a direct lift from the Alfa Romeo.... more likely, it is just the current 3.6TT with a slightly shorter stroke and the boost turned way up.
  22. Drew Dowdell
    Only 3,000 copies a year.... yet "The Avalanche is no longer a viable product" at over 10 times that???!?
  23. Drew Dowdell
    Corn ethanol is bad..... but not all ethanol is bad.
  24. Drew Dowdell
    Would be nice...and w/ a straight 6 they would probably need a longer front end, which is always a good thing.. I doubt it. The CTS front end is pretty long already.
  25. Drew Dowdell
    hatchbacks seem to have very regional popularity
