The BMW 3-Series remains the top rival to the G37; it also has great dynamics and near-perfect steering, though our editors like the steering feel of the G37 best.
On the other hand, the 3-Series is more refined, composed, and day-to-day livable—especially if you reside in a place with rough roads.
The new Audi A4 is another top rival, with its rear-biased Quattro all-wheel-drive system promising more driving enjoyment, plus top-notch materials and a cohesive design inside and out.
For those who want a sporty but comfortable choice, the Lexus IS would work; its interior is a bit more cramped and it doesn't feel as sporty overall, but otherwise it's comfortable.
The Acura TL is a slight step up in interior space, and in TL-SH guise it can be a lot of fun to drive; however it's somewhat less racy-looking.
