35 TFSI vs 40 TFSI Engines
Discussion
Has anyone driven both the 2.0 35 TFSI and 40 TFSI engines and could compare?
The 35 is showing as 150bhp and 270nm and the 40 as 190 and 320nm. Both would be auto.
I know the old 1.4 didn’t get much good press, but can’t tell much difference between the two new engines, and wondering how noticeable it would be.
Also, what any differences in fuel use etc?
Many thanks,
Dan.

Yeah I've driven both - new Q3 35 TFSI and A3 40 TFSI. Both in DSG form
The 40 TFSI (2.0 190PS) felt significantly quicker and more responsive. I found the DSG with this engine also worked much better, it seemed very laggy on it's smaller counterpart.
The economy was the only advantage of the 35 TFSI as it seemed to average about 40mpg vs 30mpg from the 40 TFSI on the same routes.

Ha a A3 auto ( courtesy car ) with 35 fsi engine for a week recently. Only city driving but engine torque was plenty to give relaxed driving. I did feel it was always one gear higher than expected ( I’m used to a 3.8 pdk so not a great comparison) and overall fuel consumption was low at 24 mpg. Dependant on your driving environment meant city= 35 fsi. Motorway work the extra power of the 40 fsi best I expect. Good luck with choice. .

Why have they started using numbers that have no correlation to the size of the actual engine? Is it a case of people just think the bigger the number the better?
It's essentially bigger is more power. It'll allow people to compare ICE and EV vehicles.
Let's be honest, nobody else seems to badge with actual engine sizes anyway these days.

Pretty much as above along with a car being badged 2.0 TDI but there being 3 or 4 different states of tune for that engine size.
Going off topic a bit but in your example it no longer has the 2.0 TDI badge, just a daft badge that bares no relation to the engine size our power output 
BMW and Mercedes can get away with it as their badging kinda makes sense. Altho a 118i and A200 are actually as pointed out a 1.5 and 1.3 they're equivalent in output to an N/A 1.8 and 2.0, so the badging is logical.
The 35 TFSI badge on an A3 does not have any relation whatsoever to its 1.5 engine capacity or 140bhp power output. It's just an arbitrary number and then when people see the badge they start thinking "Is it a 3.5 litre" etc.

It gets even more confusing where you have an A3 1.5 badged as a 35 TSI but in the A4 its a 2.0 badged as 35 TSI.
I've had a couple of people ask me if my A4 40 is a 4 litre.
