That's amazing!

eCVT amazement does not end there. Prius can climb ~20% incline at ~1,500 ICE RPM while charging HV battery.

In 5th gear the rpms are high enough for the engine to hit the horsepower peak, so it will do 196 in 5th but only 180 in 6th. It's pretty common for high performance cars with tall top gears to not reach max speed in top gear.

do you now for a fact that the top speed is not reached in the 6e gear or do you think that because the power/rpm is to low at that gear.
because when you don't have any head wind you will alway go faster in a higher gear as long that the engine is middle rpm range

don't think a corvette Will have any problems with the max speed out of that 6e gear
maybe not max torc.
if that corvette go's 1700 in 6 gear at 60mph i guess that it Will go 70mph on 2300rom and a lot faster after that
if you go back to the 5e gear it Will reach its highest rpm faster so wy do you think it Will go faster in 5e gear.. still not convinced

Hate to tell you, but priusenvy is right.

A good number of high end sports cars have a lower top speed in 6th than they do in 5th gear. Corvette is a good example. I think the Viper is the same way. You have to remember that aerodynamic drag is quadratic at high speeds and the highest gear can keep the RPMs out of the peak horsepower range.

It's worse than the square. The drag force goes as the square of the speed, but the power required goes as the cube of the speed. (Energy is force times distance, and power is energy over time, so you get force times distance over time, or force times speed.)

is this that tes drive?

YouTube - Are hybrids really more fuel efficient?

really...... one 1 tank of gas and then compare a diesel to a hybrid petrol... prius only got 45liters of fuel... the bmw.. a lot more

No the BMW took 49.26 litres of Diesel and Prius took 10 litres plus a fill up of 41.55 litres in at the end however the guy that was driving the Prius said it all, "If we had been driving through towns all the way I think this (Prius) would still be the cleanest, I think it would have won."

Where do most people do most of their driving? I know for me it's metropolitan driving.

and what amount of energy is there in that 49.26 liters of diesel? compared to the 51,55 liters of petrol.
the price of diesel here is cheaper then in the us but if you take a higher diesel price into account a diesel BMW like this one is not a good one to buy if you want to drive cheaper!

If a person drove 545 miles a week in a BMW they would, according to this test use 45 pence less worth of fuel.

The BMW premium is 6513 pounds, that is the BMW on test cost 6513 pounds more than the Prius on test.

It will take 14,473.33 weeks to recover the BMW premium, that is 278.33 years to recover the BMW premium in fuel savings over a Prius. This assumes that like in the test you driving is mainly on highways (80%) and a little (20%) urban driving. If you mainly drive in urban areas then it will be likely you will go backward.

I should point out, 545 miles a week is 28,340 miles a year, or 45.344 km per year!! If you drive less than that you will need to keep the BMW even longer than 278 1/3 years to recover the BMW premium.

When you finally recover the BMW premium you will have done over 7,388,000 miles in the BMW.

Why are we still trying to compare a 177 bhp, 140 mph car with a 76 bhp, 104 mph car?

These two vehicles are not aimed at the same type of customer. You can't draw any conclusions from a test like this.
