BMW’s biggest and most luxurious sedan is all-new for the 2023 model year. The new 7 Series boasts bold styling, a lavish interior, and now two powertrain options: gas or electric. The gas models come in six- and eight-cylinder variants while the new BMW i7 uses a 101.7-kilowatt-hour battery pack. Both the gas 7 Series and the i7 produce up to 536 horsepower.
