The BMW 850i, produced from 1989 to 1999, was a grand tourer that marked a significant shift in the brand's image. Designed to compete with the likes of the Mercedes-Benz SL and the Jaguar XJS, the 850i was BMW's attempt to create a luxurious, high-performance coupe that appealed to a discerning clientele. It was an engineering marvel, featuring a revolutionary, lightweight aluminum construction, a cutting-edge 5.0-liter V12 engine, and an opulent interior that showcased the finest materials and craftsmanship. The 850i's sleek, aerodynamic design, penned by Claus Luthe, was a departure from the more conservative styling of previous BMW models, with a long hood, sloping roofline, and a flowing, elegant profile. Powering the 850i was a potent 5.0-liter V12 engine, delivering 300 horsepower and 324 lb-ft of torque. This engine, codenamed M70, was a technological masterpiece, featuring individual throttle bodies, sequential fuel injection, and a dual-stage ignition system. It was mated to a smooth-shifting 5-speed automatic transmission, with the 6-speed manual gearbox becoming available later. The 850i's performance was exhilarating, with a 0-60 mph time of 6.4 seconds and a top speed of 155 mph. A key feature of the 850i was its advanced chassis, featuring an independent suspension on all four wheels, power steering, and anti-lock brakes. This sophisticated setup provided a balance of athletic handling and comfortable ride quality, making it both a thrill to drive and a pleasure to cruise in. The 850i's interior was a haven of luxury, featuring supple leather upholstery, rich wood trim, and an array of advanced features like air conditioning, power windows, and a powerful stereo system. Notably, the 850i was one of the first BMW models to offer an optional navigation system.
