The company car I get to use has an automatic transmission that drives me mad.
Its shift points are always right above the speeds I usually drive at.
It shifts into third at 40 km/h which is too fast for a speed limit of 30.
It shifts into fourth at 60 which is too fast for a speed limit of 50.
And it shifts into fifth at 80 which is too fast for a speed limit of 70.
So you’re constantly driving with too high rpm’s, burning more fuel and making more noise than you’d have to.
It has a “manual mode” where you can shift by moving the stick up or down. But it doesn’t actually do anything. If you shift at a different point than the automatic would, you just get a “shift denied” message on the dash, even though the rpm’s wouldn’t even get close to being too low.
And when you push the gas pedal just a bit more than half, it shifts down and the engine roars, but it doesn’t actually achieve much cause the car doesn’t have much power.
Internal combustion engines are most fuel-efficient at low rpm’s (<1500) and full throttle, and that’s impossible to do with this transmission. So it only gets 34mpg (7l/100km), and it’s a Diesel hatchback. My old manual car also had a 34mpg rating, but the way I drive I could get 47 (5l/100km), and it had a gasoline engine.
