Here is a video that Honda made to showcase it’s Honda FCX Concept. To keep things short, the Honda FCX is basically a 4-seater car running on an AC Synchronous Motor putting out 129 PS and 256Nm of torque available constantly throughout the rev range of the motor. This motor gets it’s power from a 100kW PEFC (proton exchange membrane fuel cell). Maximum range is 570km, which is comparable to a modern small car with relatively good fuel economy on mostly highway driving. Video after jump.

An engine that has surfaced and pretty much faded in a short time is Honda’s i-VTEC I Engine, a variant of the K-series DOHC engine family featuring gasoline direct injection. It made it’s debut in the previous generation 2004 Honda Stream 7-seater MPV in Japan, but the current Stream does not use this engine anymore, instead using a 2.0 litre version of the R-series i-VTEC SOHC engine.

The engine featured the ability to use ultra-lean air-fuel mixtures of about 65:1, much leaner compared to the the usual direct injection engine 40:1 ratio, and of course so much more leaner than the stoichiometric air-fuel mixture of 14.7:1 – this saves fuel. Fuel consumption dropped to 15km per litre. Power ratings remain the same at about 155 horsepower. This engine in the Stream is mated to a CVT gearbox with a manual 7 virtual gear shifting feature.

Honda also had a demonstration engine back in end 1999 where a 1.4 litre DOHC Honda engine was equipped with a VTEC-DI system. This was Honda’s first demonstration of direct injection to the public. The engine was installed in a Honda Logo (the predecessor to the Honda Fit/Jazz) and made power and torque outputs of 107 hp at 6200 rpm and 133 Nm at 5000 rpm.

Check out a video of the i-VTEC I engine after the jump.
