BMW tiptronic is pretty good, makes traffic driving easy and still retains a bit of sportiness with the up/down nudges on the open road.

Thats just an automatic. A semi auto still has a normal gearstick to select gears just no clutch pedal.

Actually, it's not. Its a semi as per the quote about gear boxes above.
An old school automatic is one where you had P, D, N, R and maybe 3,2,1 for gears for steep hills carrying load.
If you can up and down shift when you like through all the gears, it's a semi automatic. It's as simple as that.
For standard automobiles, a semi-automatic transmission is typically considered to be any transmission whereby you do not have to operate a clutch pedal. Whether the transmission itself is operating a clutch, or is a torque converter-based system, is besides the point![]()
I dont think it is that simple though because moderm auto boxes still use the same basic design as autos of old with bands in them and torque converters on the front, just the control these days lets you go up and down the gearbox(BMW market them as automatics not semi autos). A semi auto is like a DSG gearbox where its got normal gears in there that select and mesh the same as a manual box and the clutch is moved automatically.
Scanias have a semi auto box which can can click the gear stick left/right to change gear, but still has a clutxh pedal to set off with.
The difference to me of a semi auto is that they don't have a torque converter, the gearbox is more along the lines of a manual but with an automatic clutch (or two).
incorrect
mercedes AMG flappy paddle system has a torque converter, but is still classed as semi auto as it still has 1st, 2nd ,3rd, 4th,5th,6th gears etc..
not L1,L2,L3

Steven Seagal said:One is fully automatic, one is semiautomatic. The definition of semiautomatic is when you depress the trigger one round will go off.
Look Fox has already posted the Law on here, .
C63 AMG doesnt have a clutch
only the new E63 has a clutch
