    It's a shame that GM was never able to bring their HCCI engine to market. They had prototypes running back in 2008. This Hyundai engine sounds very similar to the GM HCCI.

    hahah BMW really screwed the pooch with their naming scheme.

    eh.... somewhere along the way MB forgot how to rust-proof their vans for the North American market. They don't hold up well here.

    Not a bad idear.... but I'm thinking they might be better off doing a turbo 2.5 to replace the N/A 3.6. The 2.5 is very smooth for a large 4-banger.

    The key for Cadillac in the EU is diesel engines and a vastly upgraded dealership channel. Buick is an aspirational brand in China, but they are also selling a rebadged old Opel Astra as the Buick Excelle XT for about $15000 while our Buick Verano is sold as the Buick Excelle GT for about $21,000, so though they are aspirational, they are also attainable.

    Lexus has only recently tried to crack into the European market. In China, Lexus has a bigger uphill battle due to a little fight China and Japan had 70 years ago. Cadillac has more potential for global growth than Lexus does for these two reasons alone.

    As is the Nissan NV and the Ford Transit Connect..... why wouldn't Benz want a piece of that pie?
  8. Drew Dowdell
    Sure it does... the same way that Cadillac and Chevrolet appear on the same monthly sales report.

    It's business...M-B is a full line auto and truck maker.. Why not use the Freightliner brand?

    The Encore lacks direct injection and some displacement, but it moves ok. Buick is still selling more than they expected.

    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.
  12. Drew Dowdell
    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.
  16. 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.
  19. Drew Dowdell
    With Lutz gone and Akerson on the way out... who will be left at GM to make the PR team squirm?!
  20. Drew Dowdell
    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.
  21. Drew Dowdell
    If the mustang loses weight, that's probably a good base engine.
  22. Drew Dowdell
    Just spoke to someone in the know. We'll get information on the date/venue for Canyon after the official Colorado reveal.
  23. Drew Dowdell
    2 tone paint like that needs to make a comeback.
  24. 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?
