Back in 1988, the first-generation BMW M5 wowed driving enthusiasts with a six-cylinder engine producing 256hp and 243 lb-ft of torque - capable of reaching 60mph in 6.7 seconds, which was pretty damn quick for the time. Fast forward 25 years to 2013, and the latest fifth generation M5 is continuing to fulfill its original role as a four-door sedan with supercar performance, though it’s now going about it in a different way. The 2013 M5 is more than just another model generation with a new body and interior, it’s also the first M5 to use a turbocharged V8 after years of using normally aspirated inline-six, V8 and V10 engines.
It’s a safe bet that the BMW engineers that worked on the original M5 back in the 1980’s are surprised that today’s M5 makes as much power as it does, yet is so efficient. Thanks to technology like turbocharging, direct injection and variable valve timing, the 2013 M5’s 4.4-liter V8 makes an incredible 560hp and 500 lb-ft of torque, well over twice what the original M5’s inline-six produced. What may be just as impressive as those power figures is that the 2013 M5 is a lot faster than the original M5 while getting better fuel economy, even though it weighs almost 1,000 pounds more.
