It has a nice flat torque curve, and at worst minimal turbo lag.

It's a good, plumb torque curve, which makes for easy overtaking and fewer gearchanges.

The torque curve is flatter for more pull over a wider speed range.

Total output is the same with either fuel, but the engine delivers a flatter torque curve when using premium.

What you also get is a torque curve shaped like a car's and a focus on fuel efficiency that's new to modern motorcycling.

The V-8's flat torque curve makes it possible to dawdle along contentedly in sixth gear at, say, 40 miles an hour.

The oversquare straight four engine was renowned for its big torque curve, making the car very flexible and easy to drive.

The torque curve holds flat pretty well to 4,000rpm, but after that it plummets - best keep the revs up, then.

First gear, for example, gives over 60mph without exceeding 6000rpm, and around the peak of the torque curve a 20mph increase takes less than 2secs.

The current and torque characteristic curves show the behavior of the respective starter solution.
