BMW E30 M3 Pickup - Yup, I'm gonna get this list going with the E30-generation M3, pretty much everyone's favorite vintage M car. And yes, as shocking as it may sound, BMW did make a pickup version of the beefed-up compact. It happened in 1986 when the Germans added a bed behind the front seats of a 3 Series convertible.
The prototype was originally fitted with a 2.0-liter four-cylinder rated at 192 horsepower, but the mill was eventually replaced with the M-spec 2.3-liter S14 that delivered 200 horses at the time.
The M3 Pickup did not evolve beyond prototype status, but BMW used it to haul parts and equipment for more than two decades.
BMW E53 X5 LM - Introduced in 1999, the first-generation X1 did not spawn an M version, but BMW built a one-off SUV powered by a V12 engine. The latter was a version of the iconic S70 mill, originally used in the 850CSi version of the first-generation 8 Series.
The series also included the S70/2 that found its way into the innovative McLaren F1 and the S70/3 that powered the BMW V12 LM and LMR racer cars. The X5 LM's engine was based on the latter, which enabled BMW to win the 24 Hours of Le Mans in 1999.
In short, this SUV was a ludicrous hauler fitted with a full-blown racing engine developed by BMW's Motorsport division. It did not make it into production, but it lapped the Nurburgring Nordschleife in 7:50 minutes, hitting a top speed of 192 mph (309 kph) in the process.
BMW E34 M5 Winkelhock Edition - Based on the E34-generation M5, the Winkelhock Edition was the brainchild of two-time Nurburgring 24 Hours winner Joachim Winkelhock. The German driver, who would also go on to win the 24 Hours of Le Mans for BMW, opted to delete a long list of features from the sedan in order to make it lighter.
The Winkelhock Edition arrived with reduced sound deadening and without rear headrests, vanity mirrors, rear window switches, and foglamps. He also opted for a smaller U.S.-spec fuel tank.
Unique features included an M-Technic II steering wheel, red seat belts, and a black livery with metallic silver side skirts and front splitter. BMW made only 51 cars.
Granted, the regular 8 Series was already available with a V12, as BMW launched the car with a 5.0-liter M70 good for 296 horsepower.
In 1992, it introduced the 5.4-liter M73 rated at 322 horses and the 5.6-liter S70 with 375 horsepower on tap. But the engineers from the company's M division didn't stop there.
Knowing that the S70 was capable of significantly more oomph, they increased displacement to more than six liters and added four valves per cylinder and dual overhead camshafts for each bank. The result was a massive V12 that generated a whopping 640 horsepower.
BMW E23 745i SA - It's 2022 and BMW has yet to offer a full-fledged M version of the 7 Series full-size sedan. However, the German did build a limited-edition 745i fitted with an M-spec engine. It was part of the first-gen E23 series and sold in South Africa.
While it was devoid of "M" badges inside and out, the 745i SA came with the iconic M88/3 engine under the hood. Based on the inline-six first introduced in the M1, it was shared with the first-gen M5 and M635CSi (M6 in the U.S.) and developed 282 horsepower.
Why was it only sold in South Africa, you ask? Well, this car was born out of an engine bay packaging issue.
The unofficial M7 arrived in South African showrooms in early 1984 and remained in production until 1987. Only 209 cars were made, all assembled in South Africa from complete knock-down kits shipped from Germany.
At least one car was exported to Europe, while another one was converted into a race car for the South African Modified Saloon Car Championship. Needless to say, the South African M7 is now a rare and hard-to-find gem.
