The M5 has always been one of our favourite four-door cars, especially so in its current F10 iteration. Although it’s been more than five years since this generation made its debut, it’s still one of the most potent sports saloons on sale. Now, with the next generation model expected to break cover sometime next year, the Bavarian carmaker has announced two limited edition versions of the M5. One, dubbed the Competition Edition, is limited to 200 units worldwide, while the other, called Pure Metal Silver Limited Edition, will see just 50 made exclusively for the North American market.

Both the versions have been given nearly identical performance upgrades, with power from the 4.4-litre twin-turbocharged V8 bumped up from 552bhp to 592bhp, and torque increased from 680Nm to 700Nm. Mated to a seven-speed dual-clutch automatic, the engine lets the special M5s sprint from 0 to 100kph in just 3.9 seconds. However, while the M5 Competition Edition still has a top speed limited to 155mph (249kph), the Pure Metal Silver Edition, which gets the M Driver’s Package as standard sees this increased to 190mph (305kph). This variant also gets an enhanced version of the standard Competiton Package, which include a set of 20in forged wheels, a lowered suspension and a firmer setup of the spring damper systems and stabilisers. The M5 Competition Edition also includes all the items included in the Competition Package, and hence gets a stiffened and lowered suspension, a specially programmed active rear differential, a sharper steering, and tweaked stability-control system. It comes in two colour schemes, 100 in Carbon Black and the other 100 in Mineral White, both with a metallic finish. The exterior gets carbon fibre trim, with the rear diffuser, spoiler, and mirror caps all finished in the magic weave. Meanwhile the Pure Metal Silver Edition gets a hue called, well, Pure Metal Silver, which apparently employs a paint layering process used by the BMW Individual division.

The Competition Edition is priced at 129,500 euros (Dh522,000) in Germany, while the Pure Metal Silver Limited Edition retails for $130,900 (480,000). There's no point speculating how much one of these will cost here, as BMW Middle East has confirmed to us that the Competition Edition will not make its way to our region.
