Best deals on large and luxury cars

With large cars and luxury sedans, you can expect spacious accommodations, abundant features, comfortable road trip manners, and, as our latest analysis shows, big discounts.

Based on national incentives, we’re seeing 5 to 15 percent total savings available in these overlapping vehicle segments. Interestingly, just one luxury brand currently offers such deals: Cadillac. For savings from other brands, look to regional offers and lease deals.

These are the top deals on large cars and luxury sedans for May. All the cars listed below are 2015 models and ranked in alphabetical order. Specific pricing details on these and other trim variations are available on the model pages, along with complete road tests, reliability, owner cost, and other key information.

Buick LaCrosse

Thanks to its luxurious, well-finished, and roomy interior, and a supple ride, the LaCrosse is a very competitive large sedan. Buyers can choose from a powerful 3.6-liter V6 or a mild-hybrid eAssist four-cylinder that still delivers good performance, as well as 26-mpg overall. Its engine shuts off at idle to save fuel. Handling is responsive. Rear-seat room is generous, and the seats are well padded and comfortable, though the cockpit is narrow. Exterior styling compromises visibility fore and aft, though a standard rear-view camera is new for 2015. Controls are quite simple for a luxury car.

Cadillac XTS

Cadillac's large front- or all-wheel-drive sedan has a beautifully executed interior, perfect for limo duty. It's roomy, luxurious, and quiet inside, with comfortable seats. But the ride feels too ordinary for a luxury car, and the 3.6-liter V6 engine sounds coarse when prodded. The touch-activated Cue infotainment interface is unintuitive and frustrating to use, and the high rear deck impedes the view aft. The blind-spot warning system, which vibrates the driver's seat, helps a bit. A Vsport version with a twin-turbo 3.6-liter engine gives the XTS V8-like power. A standard built-in Wi-Fi hot spot for 2015 will please passengers on road trips.

Chevrolet Impala

One of our top-rated sedans, the Impala is roomy, comfortable, quiet, and enjoyable to drive. It even rides like a luxury sedan, feeling cushy and controlled. Engine choices include a punchy 3.6-liter V6 and an adequate 2.5-liter four-cylinder, both paired with a six-speed automatic transmission. The V6 accelerates and brakes capably, with secure and responsive handling. The full-featured cabin stays very quiet, with a sumptuous backseat and a huge trunk. Controls are intuitive and easy to use, but rear visibility is restricted. Advanced electronic safety features are readily available.

Chrysler 300

Chrysler's roomy and luxurious 300 is one of the best large sedans on the market. Inside, you'll find plenty of space for five adults and a comfortable cabin with attractive trim. The punchy 5.7-liter V8 comes paired with a smooth eight-speed automatic transmission. But our preferred choice is the 3.6-liter V6, which also uses the eight-speed and brings a stately ride and responsive handling, along with a good 22-mpg overall in our tests. All-wheel drive is optional. The Uconnect touch-screen system is one of the best in the industry. The 2015 model got a mild styling update, a rotating knob for gear changes, a big driver-info screen in the gauge cluster, and a stack of modern safety gear.
