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.

Kilowatts first is a step forward.
 
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)

    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.
