Skoda Slavia 1.0 TSI 6AT vs 8AT performance compared

The 2026 Skoda Slavia facelift replaces the outgoing 6-speed torque-converter automatic with a new 8-speed unit for the 1.0-litre turbo-petrol engine. While engine output remains unchanged, our performance tests show how the two gearboxes compare in acceleration.

Skoda Slavia 6AT vs 8AT: Specifications

	Pre-facelift Slavia	Slavia facelift
Engine	1.0-litre turbo-petrol	1.0-litre turbo-petrol
Power	115hp	115hp
Torque	178Nm	178Nm
Gearbox	6-speed torque-converter automatic	8-speed torque-converter automatic

Both versions use the same 1.0-litre turbo-petrol engine, producing 115hp and 178Nm. The main difference is the transmission, with the facelifted Slavia switching to an 8-speed automatic from the 6-speed unit to offer better fuel efficiency.

Skoda Slavia 6AT vs 8AT: Acceleration timings

Slavia 1.0 TSI 6AT vs 8AT acceleration times (in seconds)
	Pre-facelift Slavia 1.0 6AT	Slavia facelift 1.0 8AT
0-20kph	1.32	1.13
0-40kph	2.80	2.86
0-60kph	4.92	4.84
0-80kph	7.78	7.57
0-100kph	11.16	11.04
0-120kph	15.61	15.40
0-130kph	18.33	18.23

The 8-speed automatic is marginally quicker in the higher-speed part of the acceleration run, although the difference is small. The 8AT reaches 100kph 0.12 seconds sooner than the 6AT. The gap grows to 0.21 seconds at 120kph and 0.10 seconds at 130kph. The 6AT is quicker to 40kph, while the two transmissions are closely matched beyond that point.

Skoda Slavia 6AT vs 8AT: Rolling acceleration timings

Slavia 1.0 TSI 6AT vs 8AT rolling acceleration times (in seconds)
	Pre-facelift Slavia 1.0 6AT	Slavia facelift 1.0 8AT
20-80kph, third gear/kickdown	6.60	6.44
40-100kph, fourth gear/kickdown	8.39	8.15

The two gearboxes are closely matched in rolling acceleration. The 8AT is 0.16 seconds quicker in the 20-80kph run and is also 0.24 seconds quicker than the 6AT in the 40-100kph test. These differences are almost negligible but tell us that with the new 8-speed gearbox, the Slavia is faster.

Autocar India’s testing standards

Before we conduct our performance tests, we check and maintain tyre pressures based on the manufacturer’s recommendations and ensure the car has a full tank of fuel. The car is then tested in a controlled environment with two people on board, and the data is collected via highly accurate GPS-based timing equipment.
