Well I'm not a Honda expert, or even one of those automotive fans who spouts numbers from heart, but I'll do my best to throw a bit of cold water on all this enthusiasm for Honda. wink
For starters, I doubt the HP standard quoted is the one that is currently accepted by designers. As I understand it -- and since I'm not an engineer my interpretation may be a bit (or way) off -- the new HP standard DIN HP will bump that 160 HP rating to roughly 155 HP, which will no longer be 100HP/L. Now what would be impressive: 100kW/L (which is the numerical value Automotive Designers actually use, not HP). For what it's worth 1 HP = 0.7456999 kW.
Even if we use the old standard, here's a bit of rant from one of my favourite anti-rice (sorry I know that's a bad word here) sites:
"102 Horsepower per Liter
"Many Honda enthusiasts smugly say, "Name me one American car that has 100 hp/liter STOCK--YOU CAN'T!" American automakers have done this before, years before Honda! In 1991-93, the Dodge Spirit R/T made 224 HP @ 6000 RPM from a 2.2 liter 16V DOHC turbo engine. This works out to 102 HORSEPOWER PER LITER! In 1993 the Dodge Daytona IROC R/Tused the same engine and made the same horsepower. Why didn't we hear more about these cars? The Honda lovers were too busy saying American cars suck!"
Please note, the attitude is not mine, even though I have absolutely no love for Honda.
I just don't see the point of them. They're over-priced for what you get (at least here) and Honda designs just don't speak to me, but YMMV. Most of the Honda fans I personally know are the antithesis of car people or automotive enthusiasts, and as such, I don't weigh their enthusiastic opinions on things automotive as highly as hold those by people who really know the automotive world.
Even though they may not be the first to hit the benchmark we are discussing, Motor Trend has a little piece about three cars that fall into the same 100 HP/L category: the Beetle Turbo S, the Vibe GT, and the Mini Cooper S.
Another mag also talks about the M3's 103 HP/L powerplant. http://www.sportcompactcarweb.com/ed..._technobabble/
As far as I can see there are lots of automotive options in the world without resorting to buying a Honda, but again, if it does it for you, go for it. And no, I'm not anti-Japanese. There are Japanese manufacturers whose products I can appreciate. I just haven't seen any Hondas that fall into that category.
