TCC’s Bottom Line

The 2008 Acura RDX gets its edge from turbo power and crisp handling, but it can feel a little nervous and cramped.

The 2009 Infiniti EX35 is an attractive choice for driving enthusiasts seeking a more moderately sized crossover.

TCC Likes

Tossable handling
Right-sized for the city
Light, direct steering

Coupe-like silhouette
The handling of a sport sedan
Front-seat comfort

TCC Dislikes

Taut -- sometimes harsh -- ride
Turbo four can seem jittery

No manual gearbox
Cramped backseat
Tech options are very pricey
