Being a car nut and a petrolhead that's a very minor issue. Minor compared to something that does my head in. Where the power is measured! At the wheels?or at the flywheel?ie - rolling road? or bench?(Or - if you like - on a rolling road but calculated for the flywheel) The fact that it could be either makes comparison a pain.

On the other hand, the conversion doesn't seem quite right. It appears that they are using one of those dinky metric horses (0.7355 kW) rather than a real American (or British) horse (0.7457 kW). Metric horsepower might be judged a little deceptive in the US, as the number is slightly inflated. Although frankly a bigger issue is probably whether the 52 kW was measured according to SAE or ISO standards (mostly the reference tempererature, pressure, and humidity) --- On Fri, 9/18/09, STANLEY DOORE <[email protected]> wrote: From: STANLEY DOORE <[email protected]> Subject: [USMA:45826] Vehicle power in SI To: "U.S. Metric Association" <[email protected]> Date: Friday, September 18, 2009, 9:52 AM AutoWeekend (Sept 18) uses the SI first when telling about the Smart Fortwo Edition Highstyle car. For example it uses "52 kW/71 hp or a 62 kW/84 hp gasoline engine." It goes on to use only kW as the unit for power in the remainder of the article. That's progress.
