TCC’s Bottom Line

The Buick LaCrosse is both supremely comfortable and excellent on gas, but we'd point you to the Premium versions if you're seriously considering one.

The 2015 Chevrolet Impala is loaded with technology and handles better previous models, and it's better looking, too.

TCC Likes

Easy-to-grok infotainment
Excellent safety record
Rides smoothly

A redefined look we'd like to see more of
21st-century infotainment systems
Strong V-6, even without the SS initials

TCC Dislikes

Interior trim isn't so premium on base models
Luxury prices on Premium versions
eAssist isn't the smoothest unit

Manual-shift switch is almost useless
Cockpit needs some chamomile
Back seat's flat, and headroom isn't amazing
