If you look at the gear ratios given here http://tinyurl.com/a9buwl2 you'll see that in 1st and 2nd they're the same, but the T4 is lower geared than the T3 in 3rd, 4th, 5th and 6th. This means that both cars will accelerate the same in 1st and 2nd (up to about 30mph in 1st and 57mph in 2nd) but then the T4 will pull away. Acceleration in reverse will be about the same for both up to a maximum of about 30mph ~ well, somebody might want to try it!

I sometimes think I should have gone for the T4, then I could have done the polestar upgrade now to 147kw. There is currently nothing yet for the T3, and we don't have HEICO here. We do, but not that covers by warranty. :-(

Volvo (dealer and manufacturer) says there might be upgrade out later in the year for the T3 from polestar. Let hold thumbs.
