How does the performance difference feel between the A3's 201 hp and the CT5's 237 hp?

The 36-horsepower difference, coupled with the CT5's RWD setup and 10-speed transmission, will translate into notably quicker acceleration and a more assertive on-road presence compared to the efficient, capable 201 hp of the Audi A3.
