how do four cylinder engines have a six gear shifter
In: 0
The last truck I drove had a four cylinder and a ten speed manual transmission. My friends dad had a Camaro with a V8 and a 2 speed automatic.
Engines like to stay the same speed, right where the torque and horsepower peaks cross over. That’s generally where the engine is most efficient. If it didn’t take forever to spin up, we could have happy little engines spinning huge flywheels at high speeds. Instead, the practical solution is a CVT. That’s basically a transmission that has infinite “gears” based on engine load and vehicle speed.
Most cars are happy with a five speed. You generally find a six speed in performance orientated cars, with some moving on to a seven speed for their manual transmission passenger vehicles. I personally think six is too much and end up skipping gears.
More and more, you’re finding automatics in performance cars and they’re faster than their manual version with ten or more forward gears (we don’t ever count reverse, unless you have a multi split axle and have more than one reverse).
