Separate names with a comma.
HSD efficiency is based on the ratio of engine RPM to vehicle speed. If MG1 is at 0 RPM, HSD efficiency is maximized. The faster MG1 is spinning,...
Not necessarily - they are claiming 41% engine thermal efficiency, but there's a few other factors to consider. That 41% is a peak number for...
They're pretty weak rumors, mostly based on the fact that Toyota's trademarked "UX 250h" - a 2.5 would be a 300h, a 1.8 would be a 200h, so 250h...
That certainly wouldn't hurt, although efficiency would be hurt. I'd say to go for more displacement before going to VVT-iW or VVT-iE, really....
Ultimately, they're not trying to compete with the Prius, though, with these systems. They're trying to compete with diesels, where a 48 volt...
Oh yeah, I forgot about that thing.
To be honest, I think there's a fair amount of room to, if they wanted to, expand the Prius lineup with performance variants. Prius S (or maybe...
Although a full hybrid is also hardware that's more easily modified into a PHEV or even EREV, whereas a mild hybrid cannot become a useful PHEV.
I would say "simpler" isn't the right word, but "easier for a conventional automaker to understand" is more correct. It's easier to tack a system...
@Trollbait already gave some examples. The Yaris Hybrid already exists (and has for several years) in the European market, and has just been...
So, undisclosed AECDs are defeat devices, end of story. (An AECD is simply anything that changes the emissions strategy, all of which must be...
In European law, that line is actually between those. In US law, automakers are required to disclose when they're doing that, and get approval...
There's a few levels of cheating, really. What Volkswagen did was detect the test (through a combination of distance versus time running, various...
The Federal government, AFAIK.
About 9 seconds to 100 km/h it looks like, that's considered slow by modern American standards, but it's faster than any stock Prius...
They're foreign-owned US companies, and one of them is even Chinese-owned.
I'm facepalming at the TTAC article's comments. The Note E-Power has a 58 kW/78 hp engine (at 5400 RPM), and the traction motor produces 80...
You could disable the power steering entirely and it'd feel different most likely. (It'd also be horrific to drive - fast steering rack, not very...
Yeah, the 2018 Hybrid starts at $37,500, versus $33,500 for the V6. ($35,250 for the same trim level V6.) It's still cheaper for Toyota to make...
New Avalon. The specs listed are for the existing Avalon.
