    2nd Gen Cruze EPA Ratings Better Than 1st Gen Eco

    EPA ratings are out for the 2nd Gen Cruze. With a 1.4T and 6sp Auto, it's rated at 42 Hwy, 30 City, 35 combined, which is better than the 1st Gen Cruze Eco Manual (42/28/33). Not a small feat, though the highway number is the same despite better aerodynamics, which makes me think weight reduction (-250 lbs) and better tuning of the automatic transmission are largely responsible.

    Apparently the ratings fall ever-so-slightly with the 6sp Manual, to 41/29/33 combined.

    The Premier version gets worse mileage, only 40 MPG highway. Maybe larger wheels/tires and/or non LRR tires play a role there? Maybe less aero friendly bodywork?

    Here's the whole story:

    2016 Chevy Cruze gas mileage beats even previous Eco model

    I forget which other compact car it is (Corolla?) where tire/wheel combinations also make less MPG on the highway.

    It looks like the 16 keeps the standard M32 instead of the triple-OD Eco gearbox. Fine by me (and I'm sure a disappointment for all you Eco owners ), but 6th could definitely be a LITTLE taller.

    Cool

    I read that both HP and Torque are up with this 1.4 Engine ..
    Is this a Direct injected engine now ?

    250 lbs.lighter and a better tune for the transmission ..this is where those increases in torque and HP come from .

    DI, and new engine design (all-aluminum vs cast iron block and aluminum head for the old 1.4). It makes more power, and has less Cruze to haul around too.

    Hey j . Peeps are going to blow these tiny boogers of an engine UP ...

    POP , yep ...Peeps just have to be overly enthusiastic and overboost and feed to much fuel ..even the oil will POP this booger ...

    Pre Ignition !

    That's why you get a tuner that knows what they're doing.

    Start/stop technology also plays a role.

    That would only be a veriable in the equations .
    If 1 chooses to increase the numbers with out considering the limits to stresses of the internal components ie. Connecting rods , bearings , pistons ..then you would still run the risk of an event that exceeds these limitations ..remember that these are manufactured parts for GM that come with a degree of cost effectiveness and have fail rates ..

    These peeps with the 2.3 are POPing at a rate of 2 a week now and have to admit that the responsibility is they'res alone and Ford is Not Warrantying the Blown engines at the techs level ..

    These conditions are not new and can be tŕaced back 80 years .
    Stochastic Pre Ignition ..LSPI ...Low Speed Pre Ignition today .

    My purpose here is to pass these ideas around to allow individuals a choice when looking at Modifications and the drawbacks of getting to envolved with more HP and More Torque .

    Buyers beware of Boost max and throttle enhancers !

    I think Ford is pushing the 2.3 (especially in the Focus RS) and 2.7 EB engines very close to their full potential on pump gas on stock tunes.

    The same could not be said for GM with the first-gen LUJ/LUV - it is an EXTREMELY conservative stock tune that runs very rich and pulls timing at the first hint of knock. Direct injection gives them/a tuner a lot more fine-tuning and knock is easier to keep under control. That said, they will be using power-coated instead of forged rods on this new engine. Pistons were the weak point for the old 1.4, though.

    How do you or even a tuner avoid Preignition from the oils ?

    Flash points . Here in lies certain aspects of the phenomena and theories of stochastic preignition ..

    Granted there is great strides with modern engine oils to increase the flash points to resist combusting before TDC and stressing against rotation ..A variable certeinly exists when an individual increases boost and runs worn out oils ..

    If in the future if we are reading how the 1.4 is poping will GM replace the direct injected engines internals or just brush this extreme engine failure off as a cost of doing buisness and the consumer be aware ?
