There are rumours that VW is under rating the horsepower on the 1.8T cars in order to boost sales of the new six cylinder engine.
I have read here on the Vortex that people with STOCK, late model 1.8T cars have dynoed 175 HP AT THE WHEELS!!!
Think about that. The 1.8T cars are cheaper and lighter and may have as much power as the new six. You might not get a few of the extra bells and whistles, but you get a quicker car.
If it is true then the new 1.8T cars are a bargain
They are describing flywheel horsepower. There are little differences between English horsepower and US horsepower due to different "politics", but brake hp = hp.
Some will measure engine power by removing the engine from the car and measure off the flywheel. This is flywheel hp or crank hp.
Another way is to drive the car on to a chassis dyno, or "rolling road" as it's called in the UK. The power is measured, and some fancy math and often a lot of fudging is done so that they can calculate the flywheel, or crank hp. The math is done to account for power loss thru the transmission,driveshaft(s), and tires, plus to correct for differences in atmospheric temp and pressure.
