That’s pretty awesome, the Cruze makes a great road trip car. Also still amazes me I was able to squeeze 43 mpg out of a 2001 Saturn.

According to the EPA, the Cruze diesel sedan paired with a six-speed manual transmission (yes!) gets 30 mpg city, 52 mpg highway, and 37 mpg combined. With a nine-speed automatic, the figures are 31 mpg city, 47 mpg highway, and 37 mpg combined.

if i can put a small hitch and tow 1500lbs with it, i’m sold.

not anymore. turbocharging is what gets you torque; diesel’s reputation is because diesel engines are immune to detonation, and have been able to use high pressure turbocharging for decades. GTDI engines have caught up (or even surpassed) diesels in torque, and put out way more horsepower.

doubtful. one of the reasons the EPA was empowered to assess such enormous fines was to make examples out of violators. (hopefully) no automaker would be dumb enough to try it again after seeing what happened to VW.

And, also worth noting that BMEP (in a roundabout way, specific torque) has always been higher for gasoline engines for a given boost pressure. That’s because gasoline engines can get more fuel in for a given volume of air - diesels suck at mixing the fuel and air, and therefore you have to run lean or you get smoke.

Well, seeing how VW got caught doing this in 1973-1974, and the heavy duty diesel manufacturers got caught doing this in the mid 1990s...
However, this time around, anything light duty and diesel is being put through the wringer by the EPA, which has delayed certification on everything but GM and BMW model year 2017 diesels.

honestly, torque production (and torque peak) is independent of cylinder count or layout. An engine’s torque output is a function of its brake mean effective pressure (BMEP) and its displacement. the bore and stroke will influence where it makes peak torque. in general, an engine which “everybody knows” is “great at torque” really just sucks at making horsepower. as an example, the old Ford 300 (4.9) inline six is revered as a “torquey” engine. The problem is that the 302 (4.9) Windsor V8 offered at the same time produced 15 more lb-ft of torque, at only 100 or so RPM higher. the six had about 50-60 less horsepower.
Turbochargers bring “low-end” torque because their output is based on engine load, and not engine speed like superchargers. diesels can’t suffer pre-ignition/detonation, so for 30+ years now they’ve been able to use high pressure (15+ psi boost.) Gas engines are prone to detonation if chamber temps get too high or they go lean. Ever since direct injection has come to gas engines, the game has changed. with GDI, the fuel evaporates inside the cylinder/chamber instead of in the intake tract. the fuel going through a phase change (evaporation) cools the air:fuel charge, so GTDI engines can maintain a high static compression ratio, and use high levels of boost pressure. Some people twitched their eyes when they heard that the EcoBoost 2.7 in the F-150 was running peak boost pressures of 22 psi. diesels have been doing that forever; and now with DI gas engines can too.

True, I snagged a 2016.5 CX-5 for a reasonable deal in December when I sent the TDI back to VW. I do miss the three pedals, I would love to replace our Corolla with a Mazda3 6MT but that isn’t in the cards yet.

plus, diesels are more or less capped to about 5,000 rpm or so before they fall off a cliff.

It was a joke. But since this seems to be your thing, what do you think about the jet ignition being utilized in F1?
"bhtooefr" (bhtooefr)
02/13/2017 at 19:38, STARS: 0
Well, that wouldn’t affect BMEP - that’s independent of RPM. (Well, if you can get a higher torque peak by putting it above the 4000-5000 RPM limit (depending on your combustion technology) for diesel combustion performance...)
"jimz" (jimz)
02/13/2017 at 19:43, STARS: 0
I know that, but it’s a factor limiting the horsepower a diesel can make.

it’s another take on stratified charge combustion. a rich “zone” around the ignition source, but an overall lean mixture. Honda’s CVCC was an early example of a stratified charge engine.
"BeaterGT" (beatergt)
02/13/2017 at 19:47, STARS: 0
Yeah...but what do you think?
"jimz" (jimz)
02/13/2017 at 19:57, STARS: 0
it’s a pre-combustion chamber similar to CVCC and diesels from the ‘60s up through the ‘80s. it works for F1's purposes, but they don’t have to worry about emissions. I don’t see how it wouldn’t cause a problem with meeting NOx emissions standards. high chamber temps and lean combustion contribute to NOx formation, and there’s only so much a simply three-way catalyst can handle before it’s overwhelmed. See, the ball-ache with meeting emissions standards is the fact that the trace emissions which have to be cleaned up have diametrically opposite requirements. unburned hydrocarbons (HC) and carbon monoxide (CO) can be easily cleaned up via an oxidation catalyst. with an oxidation catalyst, as long as there’s sufficient excess oxygen in the exhaust stream, the HC can be oxidized into H2O and CO2, and the CO into CO2. On the other hand, cleaning up oxides of nitrogen (NOx) requires a reduction catalyst, which doesn’t work if there’s too much free oxygen in the exhaust. it’ll just pull that free oxygen instead of stripping it from the molecules of NOx.
its for those reasons the engines of road cars constantly oscillate between slightly rich and slightly lean. they need to keep both the oxidation and reduction catalysts working. Running constantly lean (as in the F1 jet ignition) would mean they couldn’t control NOx.
