I've test driven one this morning, having the same concerns, especially coming from a Jetta 1.4 TSI. I was pleasantly surprised at how it performed considering it's brand new, so the engine will still be tight. I expected it to be very lethargic, but as long as I was mindful of keeping the revs above 1500rpm, it performed very well. On the highway, it kept its indicated 130km/h up a very steep hill. The engine loves to rev and I love the three cylinder thrum it makes. But, should the need arise to change down, it shouldn't be a hassle as even the gear change is super smooth and easy.
