10 Alternatives to the 2018 BMW 6 Series

These Outstanding Cars Will Impress BMW 6 Series Buyers

The 2018 BMW 6 Series lands in the middle of our luxury large car rankings. It’s a solid cruising car and offers multiple powerful engine options. Its premium cabin is quiet, even at high speeds, and comes with a large, user-friendly infotainment screen.

The 6 Series is available as a four-door, five-seat Gran Coupe (sedan) or a two-door, four-seat convertible. BMW eliminated the two-door coupe for the 2018 model year. While the 6 Series is an exceptional car in many ways, it doesn’t stand up to some rivals in certain areas. It has cramped back seats, lacks some tech and safety features found in competing models, and has a higher starting price ($81,400) than most cars in the segment.

Choosing a vehicle to replace the old standby requires a considerable amount of research. So, to make your job easier, we’ve done the hard work for you. This slideshow lists the price and U.S. News score of each vehicle, as well as other valuable information about each model.

Keep in mind that we regularly update the scores on our site as new expert reviews and data become available, so the scores in our rankings and reviews may not match up with scores in this slideshow.

2017 Mercedes-Benz SL

$86,950 | U.S. News Score: 8.8/10

The Mercedes-Benz SL is a two-seat hardtop convertible, but it’s similar to the four-seat soft-top convertible BMW 6 Series. These cars have very comparable starting prices, and they’re both hard to beat if you’re looking for a refined, comfortable cruiser that’s oozing with luxury. While the Mercedes costs nearly $2,000 more, it comes with additional standard active safety features, and it’s more reliable.

2018 Porsche 911

$91,100 | U.S. News Score: 9.1/10

It’s arguably one of the most iconic sports cars on the road today, with five powerful engine options and incredibly athletic handling.

2018 Mercedes-Benz E-Class

$52,950 | U.S. News Score: 8.9/10

The last BMW 6 Series alternative may come as a bit of a surprise; it’s also the least expensive car in this slideshow.

The luxury midsize Mercedes-Benz E-Class was completely redesigned for the 2017 model year, and there’s almost nothing not to like about it.

It features a 12.3-inch infotainment system with Apple CarPlay and Android Auto, along with just about every safety feature on the market today.
