I'm by no means an expert in this area, but I do have a few thoughts and requests for clarification.
How was the "98hp in 110 kph" test performed? Was this on a dynomometer (aka "dyno") or using math and accelerators (like a celphone application)? Is the horsepower rating supposedly at the wheels or at the crankshaft? What's the car rated to have?
An engine speed of 2k at 60 kph in 5th gear does seem pretty high. Are you absolutely certain you were in 5th gear and not 3rd? Does the clutch seem to be good? Is the transmission a 5-speed or a 6-speed?
