S-Tronic Audi A3 gets auto start-stop system
Audi has added start-stop technology to its automatic transmission cars. Normally other than in a hybrid paired to some kind of CVT or e-CVT, auto start-stop systems have traditionally only been available with manuals, as they are so far with cars from manufacturers like BMW.
It’s abit of a grey area here as the A3’s auto start-stop system is technically not mated to an automatic transmission in the traditional sense. It’s not a proper slushbox but is instead an S-Tronic (DSG) twin clutch transmission, which is sort of like a manual but with two computer controlled clutches.
The auto start-stop system helps the 105 horsepower 1.6 liter TDI engine deliver a fuel consumption of just 4.2 liters per 100km. With the 1.4 TSI with 125 horsepower, consumption is rated at just 5.3 liters per 100km.
These figures also include a brake energy recovery system that is used to assist the alternator. Mind you, these are real figures on a combined driving cycle, not some highway-only kind of mileage! Impressive stuff!

It’s amazing that the European car manufacturers are
taking the lead to produce such fuel efficient cars instead
its Japanese counterparts. We have this mindset that Japs
are more fuel efficient. Hopefully we get to see more TDI
models at our shores and hopefully they can run on Euro2.

Audi’s hatch is not “hot” enough. Very safe design aka “lame design”
i believed VW/SEAT does better in hatch segment.

‘I definately do not want to drive this car and get ‘tapao’ by Vios everyday.’
A3 TDI: 250 Nm at 1500 rpm, 0-100 kmh: 11.4s, top speed 194 km/h
Vios: 141Nm at 4200rpm, 0-100 kmh: 12.5 secs and 174 km/h.
Not to mention 4.2l/100km versus 7,69l/100km…

Lexus is really the pioneer in this. The RX 400h had stop / start with an auto back in 2005.
Yes, OK, its an e-CVT, but that’s just as much an ‘auto’ as S-Tronic…..
