The 8 Series returns as a luxury four-door coupe or convertible. The 8 is a resurrected series that was BMW's flagship coupe in the 1990s, designated as the 840i and 850i. It's meant to compete with other six-figure boutique cruiser-type cars, offering a mix of pampering, high tech, power, and exclusivity. For 2019, the 8 has a turbocharged V8 engine, mated to an eight-speed automatic and all-wheel drive. We found that combo to be super-slick, punchy, and relatively fuel-efficient in the 7 Series we tested. The 8 Series promises a combination of luxury and high tech wrapped in a sporty, stylish silhouette.
