The BMW 8-Series (E31) is a luxury grand tourer produced by BMW from 1989 to 1999. It was the flagship model for BMW, offering a luxurious and sporty driving experience. The E31 was the first BMW to feature a V12 engine since the 1930s, and it was also the first BMW to use a fully independent suspension system. The 8-Series was offered in a variety of engine options, including a 5.0L V12, a 4.4L V8, and a 3.0L inline-six engine. These engines were mated to either a five-speed manual or a six-speed automatic transmission. The 8-Series was also notable for its sleek and aerodynamic design, which was penned by the legendary designer, Claus Luthe. It featured a long, low-slung body with a distinctive, almost shark-like profile. The interior was equally luxurious, featuring high-quality materials and comfortable seating. The 8-Series was a technological marvel for its time, with features like ABS, traction control, and an optional navigation system. However, the E31 struggled to achieve the same commercial success as other BMW models. The high price tag and relatively low production volume contributed to this. Despite its commercial challenges, the BMW 8-Series remains a highly desirable and collectible car. Its powerful engines, luxurious interior, and iconic design continue to captivate car enthusiasts today.
