Chrysler sells the Hellcat crate engine as 707 HP. The “707 hp” Hellcat engine already makes north of 750 by almost any measurement, so it is likely they’d be probably 850-900 if measured by the old gross standard. Given a 3.0 blower (vs. 2.4 in the original Hellcat) and 426 cubic inches, it’s almost impossible to…

3.0 liter blower vs. 2.7 and 426 cubes vs. 376.

So it beats it in every metric except the entire reason to get a wagon?

Many Honda autos were basically parallel shaft manual transmissions with clutches replacing the synchros and up to three shafts. 

It’s simply my annoyance at the Koenigsegg worshippers. I’m not blaming Koenigsegg for going this direction, just expressing my frustration about those without an understanding of what already exists; so easily impressed. I agree with you that it’s VERY hard to really bring out something new these days. I’ve submitted…

So it’s basically a beefed up Honda Automatic transmission from the 90s? I swear every “OMG, never-before seen” innovation from Koenigsegg looks like something Honda already did. And before you think me a Honda fanboy, I’ve never owned one, not considered buying one.

People act like these new weapons are quantum leaps, unimagined when these carriers were built. The Soviets had Mach 4.5+ anti-ship missiles in the 1960s. The U.S. had Mach 3.5+ attack missiles in the 60s/70s as well. In the early 80s, we had steerable re-entry vehicles deployed on Pershing 2. Minuteman also tested…

Icebreakers need a disproportionate amount of power per size. Gas turbines are better at this than diesels. CODAG is best if not going nuclear.

Unless I’m missing something, most Ohios have 24 missiles with w88 warheads of 475 kT each.

15% on gasoline*

The Volt already hardly ever uses the engine (I have one), so that’s not super unique. However, a fixed RPM generator at very low RPM would almost assuredly weigh more than a higher RPM solution, thus further exacerbating the problem. As it is, the 1.5 Volt engine is already a bit of a stump puller, with much of its…

Diesels are expensive and not much more efficient than Atkinson cycle gas engines (probably doesn't cover the fuel price difference in most states). They also weigh more and produce most of their power at low RPM. These two traits do not complement a vehicle that already will struggle with weight and produces full…

Just like Hyundai and Chevy’s imminent HCCI technology. Production is quite challenging! Mazda seems more prone to release stuff that’s almost there these days (SkyActiv-D for instance), so maybe we'll see it.

Turbo cars are far less affected by altitude, as they have a compensation device. Yes, compressor and intercooler efficiency fall, but turbine backpressure is not linearly impacted by this and the intercoolers are just oversized to compensate.

Better, but still too Civic Type R for me.

All Gen III Hemis are two valve, twin plug. Mercedes 3V engines are also twin plug. That's a pretty neat head arrangement, actually.

GM is doing a ton of great things right now. They are quietly producing some of the lightest vehicles in class; have phenomenal chassis tuning; lead in many aspects of electrical vehicles, batteries, hybrids, and autonomous driving; and make many wonderful engines/transmissions. However, they really need to get…

My Volt loses very little when I switch to X-Ice 3s. The Nokian Haveafajitas are supposed to be low rolling resistance too. I was surprised.

Nearly all of the Volvos, several acuras (RL and NSX as well), Lexus Rx450, Porsche 918... Not exactly a new idea.
