Used 2018 BMW M5 for sale 

BMW's programmable powertrain can be utilized to switch power distribution to send power from all wheels to just the rear wheels. The added performance bonus is the 2018 BMW M5's capability to slide and perform some incredible drifts. 

As seen from the table, the 2018 BMW M5's primary competitors are the Audi RS7, the Cadillac CTS-V, and the Mercedes-AMG E63 S. These vehicles stand at par with the M5 in terms of performance and are all approximately on the same cost bracket, with Cadillac CTS-V costing a little less. Comparing the competition, the Cadillac CTS-V offers a ballistic horsepower figure of 640 for the price you pay to get your hands on one. While the BMW M5 and the Mercedes-AMG E63 S offer a similar amount of raw power, the Audi RS7 is shy of about 40 horses from the former two. The Cadillac CTS-V also boasts the highest torque number, while the Audi RS7 offers the least among the competition. 

2018 BMW M5 Acceleration and Braking Performance

In all kinds of driving scenarios, we can comfortably state that the 2018 BMW M5 is the best among its counterparts. The 8-speed automatic transmission shifts quickly which gives it an edge over its rivals and helps the M5 get to the speed of 60 miles an hour in an astonishing 3.2 seconds.

The 2018 BMW M5 also manages to cross the quarter-mile mark in a face-melting 10.9 seconds, which genuinely brings its performance in the supercar territory. 

Inferring from the table, the 2018 BMW M5 is at the top with 3.2-second 0 to 60 time, followed closely by Mercedes-Benz AMG E63 S with 3.3 seconds. Also, the BMW has the fastest quarter-mile than the others, with the Mercedes-AMG being the slowest quarter-mile runner. While the engineers at Cadillac have managed to design the CTS-V with a curb weight of just 4141 pounds, the BMW M5 weighs just a few hundred pounds more and manages to deliver the best braking distance.

Comparing the competition, the M5 comes with Cadillac CTS-V at the bottom of the barrel, with combined economies of 17 MPG, while the Mercedes-AMG E63 S comes at the top with a combined economy of 21 miles per gallon. The Audi RS7 trails in between, with an acceptable MPG figure of 19. The Mercedes-AMG E63 S, albeit offered with low gas mileage, comes equipped with a healthy 23.8-gallon fuel tank, which delivers a range of 595 miles, the highest among its competition. The Cadillac CTS-V comes with the smallest fuel tank, and offers the least range, making it a tad less practical than you'd expect. 

The interior can be customized to sport various colors such as jet black and tan, but the M5's sporty interior truly comes alive in the white finish. The cabin is adorned with leather and brushed aluminum accents, with ambient interior lights accentuating the cabin's luxury at night. The M5 also sports a leather-clad steering wheel and a hybrid gauge cluster. Tech features such as head-up display and Real-Time Traffic Information have been added for enhanced convenience. 

From the table, it gets clear that there's a bit of disparity in terms of interior space. At the front row, the Cadilac VTS-V offers the most headroom and legroom, while the 2018 BMW M5 comes with the most shoulder space. At the back row, the Mercedes-AMG E63 S has the most headroom and shoulder space to offer, while the Audi RS7 comes with the most legroom at the rear.

Also, the M5 has a better passenger seating capacity than the Audi RS7. The only place the RS7 beats M5 is at fuel economy, which certainly is a point to consider in terms of practical usage.

Cadillac CTS-V:

The Cadillac CTS-V offers a more powerful alternative to the BMW M5, being lighter and a little more nimble than the German performance sedan. The Cadillac also comes with a manic supercharged engine, which certainly adds symphony to the driving experience of the Cadillac.

The CTS-V also offers an equally decent fuel economy as the BMW M5, but the latter has a much more refined driving experience. Interior quality and reliability is also BMW's game, with the Cadillac falling short on vital aspects of the CTS-V's longevity. 

Mercedes-Benz AMG E63 S:

Mercedes-Benz AMG E63 S gives a tight competition to the BMW M5 but falls short on some accounts, such as infotainment technology and interior plushness. The AMG, however, does offer a better 8-Speed automatic gearbox, and a more efficient V8 engine.

Practically speaking, there are aspects of the BMW that cannot be compared to that of the AMG, and vice-versa. Therefore, it really comes down to personal preference, on the grounds of performance, luxury, exterior styling and brand preference.
