The Turbo Premium is the lowest-spec turbo offering in the range, but it adds even more features to the 2.5 S Premium’s equipment list. It's more distinctive on the outside, thanks to a larger tailpipe, shark-fin antenna, and 18-inch alloy wheels with a metallic black finish. On the inside, you get a 12-speaker Bose sound system, along with a heated steering wheel and a frameless self-dimming rearview mirror.
