The BMW 8 Series, launched in 1989 and produced until 1999, was a luxury grand tourer that aimed to compete with the likes of the Mercedes-Benz SL and the Jaguar XJS. It was the first BMW to feature a V12 engine since the legendary 328, and its sleek, aerodynamic design, penned by Claus Luthe, broke new ground for the German marque. The 8 Series was initially offered in two variants: the 850i, powered by a 5.0-liter V12 engine producing 322 horsepower, and the 850Ci, a more luxurious version featuring a longer wheelbase and additional interior amenities. In 1993, BMW introduced the 840Ci, which employed a more fuel-efficient 4.4-liter V8 engine producing 282 horsepower. All models featured a 6-speed manual transmission or a 5-speed automatic transmission, and were lauded for their potent performance and refined handling. The 8 Series also pioneered several technological advancements, including the use of a lightweight aluminum chassis, a unique double-wishbone suspension system, and an advanced traction control system. Despite its groundbreaking technology and elegant design, the 8 Series faced challenges in the marketplace. Its high price and complex engineering resulted in relatively low sales figures, and the 8 Series was discontinued in 1999. However, it remains a highly sought-after classic, admired for its distinctive styling, performance, and luxurious appointments.
