Luxury automakers may be following in the footsteps of their mainstream counterparts with a push towards crossovers, but the traditional car remains a popular purchase for well-heeled consumers. But to capitalize on continued investments in cars over crossovers, automakers are stretching these low-riding platforms into different forms. Our top luxury pics follow a similar trend of giving customers choice (provided they're willing to go to just one brand's dealerships). Each of these vehicles is available as a two-door coupe or convertible, a four-door sedan, or in one vehicle's case, a five-door wagon.

Combined with plentiful powertrain options, our picks for the best luxury cars of 2018 might only include three vehicles lines, but there's a lot more too choose from here. Why it's a top pick: It’s not an exaggeration to call the compact C-Class a miniaturized version of Mercedes-Benz’s flagship S-Class sedan, boasting the segment’s best cabin. The materials are lovely, the technology advanced, and there’s enough space for four adults. Gas, plug-in hybrid, and high-performance variants, not to mention coupe and convertible bodies to complement the sedan lineup, make the C-Class an impressive all around luxury product.

Worth knowing: A refreshed model is coming for 2019, taking even more cues from the S-Class while emphasizing its cutting-edge active safety systems. Why it's a top pick: Competition from Audi in the form of a new A6 and A7 is on the way, but until they arrive next year the Mercedes-Benz E-Class remains our top pick. Like the C-Class, it’s available in sedan, coupe, and convertible body styles (not to mention a wagon), with powertrains ranging from frugal to furious and among the most advanced active safety and driver assistance technologies on the market.

That's not a joke - the E-Class can maintain a distance to the vehicle in front of you, brake when they do, and keep you positioned in your lane. But properly equipped, it will also change lanes automagically. The E-Class isn't autonomous, but it's darn close. Worth knowing: Look to the E-Class for the best example of Mercedes’ interior dominance. It’s unquestionably the class of the field, with fine materials, fascinating design choices, and a wealth of upholstery, color, and trim options for maximum personalization.

Why it's a top pick: The standard for luxury on the affordable side of the Bentley and Rolls-Royce, the Mercedes-Benz S-Class is among the most competent all-around vehicles in the business. Like the C- and E-Class, it’s available in a range of body styles and powertrains, but it’s the available Mercedes-Maybach line, featuring stretched bodies and heavily revised interiors, that allows the S-Class stand out. Worth knowing: The Mercedes-Maybach line is to luxury what Mercedes’ legendary AMG range is to performance. Only available on S-Class models, the Maybach setup elevates the passenger experience to a level that rivals the masterpieces from Bentley and Rolls-Royce.

And the car's standard 60/40-split folding rear seats provide extra versatility to accommodate outsize items. Standard blind-spot warning gives every Sonata driver equipment that facilitates safe lane changes. Blind spots can cause drivers to make unsafe lane changes, and this can lead to close calls or something far worse. For this reason, a blind-spot warning system is viewed by many car shoppers as essential equipment. In many models, blind-spot warning is offered as an expensive option, but this isn't the case with the Sonata.

This Hyundai provides both blind-spot warning and rear cross-traffic alert as standard equipment. When you pair this with the sedan's affordable starting price, it's easy to see why the Sonata represents good value. The Sonata offers engine choices that provide excellent fuel economy. Family cars typically spend ample time on the road. They tend to rack up lots of miles, whether it's from shorter daily commutes or lengthy cross-country road trips.

The Sonata comes with engine choices that offer superb mileage, and this can make your travels more affordable. With its available 1.6-liter engine, the Sonata achieves EPA-rated fuel economy of 28/37 mpg city/highway. There's also a traditional hybrid variant that gets mileage of up to 40/46 mpg. And for maximum green points, the Sonata offers a plug-in hybrid that gets mileage of 99 MPGe. Apple CarPlay smartphone mirroring is standard on the 2018 Sonata. Remember when pretty much the only thing you could do in a car was drive,

These days, it's easy for passengers to keep themselves entertained when they're on the road. And with family vehicles, modern tech matters for both parents and kids. Hyundai's Sonata is equipped with standard technology features designed to keep everyone happy. Base models come with features such as Bluetooth phone connectivity, a 7-inch touchscreen, and Android Auto/Apple CarPlay smartphone integration.

With its strong crash-test ratings, the Sonata is built to protect you and your loved ones. A family car is more than just a place for passengers to while away the hours on boring commutes. These vehicles also provide protection that can keep your family safe during collisions. The Sonata's crash-test ratings should give parents peace of mind.
