Among compact sport sedans, it's the BMW 3-Series that's definitely the top rival to the G37.
And with the 3-Series redesigned this past year, it's tougher competition than ever.
The latest 3-Series has a fuel-efficient turbo four-cylinder engine offering up to 34 mpg highway, yet its handling retains some of the expected sharpness (with excellent steering).
A turbo six is also offered in the 335i models.
The Audi A4 is another top rival, with its rear-biased Quattro all-wheel-drive system promising more driving enjoyment; it has top-notch cabin appointments, although it's quite tight inside.
The interior of the Lexus IS 350 is also quite cramped, with a design that looks more dated, and it doesn't feel quite as sporty overall as the G37.
The Acura TL, in its performance-oriented TL-SH guise, would make a good alternative to the G37 if you size up the G37 as just too cramped and noisy.
So actually would be the somewhat larger, somewhat more refined Infiniti M sedans, which are still quite engaging.
