There are three 2023 BMW 8 Series Gran Coupe trim levels to choose from. The lineup kicks off with the RWD 840i and extends to the 840i xDrive and M850i xDrive. Both 840i models are powered by a 3.0-liter turbocharged six-cylinder engine producing 335 horsepower.
All models get standard LED headlights, a panoramic moonroof, remote engine start, keyless entry, soft-close automatic doors, and a 12.3-inch central infotainment display with Apple CarPlay and Android Auto. Driver assistance features include lane departure warning, frontal collision warning, and automatic city collision mitigation.
The M850i xDrive is powered by a twin-turbo 4.4-liter V8 engine producing 523 hp and includes a sport exhaust system, an M Sport differential, and M Sport brakes with blue calipers.
The price of the BMW 8 Series Gran Coupe starts at $87,400 for the base 840i. This is the lowest price and excludes tax, registration, and a handling fee of $995. Adding AWD brings the price of the 840i xDrive up to $90,300. The top-of-the-range M850i xDrive will cost you an MSRP of $102,400 but can surpass $122k depending on how many extras you want and what options packages have been added. By way of comparison, the most affordable Porsche Panamera starts at $92,400, but to get to M850i xDrive levels of performance, you'll have to fork out $141,400 for the Panamera GTS Sport Turismo.
840i and 840i xDrive models are available with Driving Assistance Package, which is priced at only $100. Opting for this adds Parking Assistant Plus, active blind-spot detection, active park distance control, and a surround-view camera. A further upgrade to the Driving Assistance Professional package is priced at $,1700, but requires the $100 Driving Assistance bundle to be selected too. This adds all those goodies plus radar-based assistance systems in the form of Active Driving Assistant Pro and traffic jam assistant too. The $650 M Sport Professional package includes M Sport brakes, extended Shadowline trim, and Shadowline headlights. Standalone options include glass controls for $650, a Bowers & Wilkins sound system for $3,400, and integral active steering for $1,150.
The M850i xDrive can be equipped with the $1,550 Cooling and High Performance Tire package, which adds the M Sport Professional Package, unique 20-inch wheels, and increased capacity of the braking and drivetrain cooling systems. Individual options for the range-topper include an M Carbon roof for $2,800, rear seat heating for $350, the M Carbon Exterior Package for $4,100, and BMW M 50 Years emblems at $200.
At this level of motoring, we'd want a bit more than 335 hp, which is why we'd go for the top-end M850i xDrive. Not only is this car a pleasure to cruise with on the open road, but it can also surprise through the corners and will launch off the line like lightning. The exterior specifications of the M850i xDrive aren't that different from the standard 840i, but we appreciate its sleeper looks. Under the skin, this M car features uprated suspension, massive performance brakes, and an M Sport differential. The interior also features ventilated front seats. If we were buying, we'd add the Driving Assistance Professional Package and the Cooling and High-Performance tire package for a total cost of $106,050, excluding destination.
