Officially, the hot hatch has a power output of 316bhp and 400Nm of torque from its 2.0-litre turbo four. While it isn't as powerful as the Ford Focus RS's 345bhp, the grunt available is good enough to help Honda reclaim the FWD 'Ring record.

 

So does the car really have 316bhp only in the real world?

 

A garage from Spain has managed to get its hand on one unit and strapped it onto its dyno to record an impressive 295 wheel horsepower. Assuming a 15 percent power loss from the engine to the wheels, the car is actually producing 347bhp at the engine which is around 30 more horses than declared and is nothing to be laughed at.

Two things:

 

1) there is no easy way to correlate crank to wheel hp. 15% is a BS figure that's thrown around too often without understanding.

 

2) underrating HP is quite common in the sports car/hatch game.

I think for this engine it's built to allow overboost (e.g. +0.5 bar for 30 seconds). I think for most modern turbocharged engines they are built to allow certain amount of overboost for a short period of time. Which can easily translate to more power.

Usually car makers do not declare the overboost rating as it might not be activated on demand by the driver but rather on certain conditions. Hence they give a more conservative rating.

  • Is 'tiny living' really irrelevant in Singapore?

    I discussed the possibility of living in tiny houses in Singapore in an earlier blog post. But as we know, it isn't an option to begin with – no thanks, of course, to our lack of land space.  Someone also pointed out that the idea of tiny houses is "romanticised" – which, I don't deny (but hey, that's why it's a dream). While it's clear tiny houses aren't going to work out here, the concept of 'tiny living' is; not just physically but also mentally. Anyone who has lived enough years lo
