BMW will unveil a new 8-Series transmission car before a new two-door public debut later this month at the Los Angeles Auto Show.
Meanwhile, lightly disguised prototypes of the upcoming M8 flagship of M Executive Cars (below, left) hit the racetrack because the engineers gently tuned their chassis and assistant systems in the final round of testing the luxuriously fitted two-door door.
The concept model, designed to compete with the latest state-of-the-art convertibles, including the latest Bentley Continental GTC and Mercedes-Benz S-Class Convertible, represents the new open-top BMW model of the revamped 8-Series, including the newly introduced 8 Series Coupe the upcoming 4 8-Series GranCoupe will be introduced later next year.
The indirect replacement of the former 6 Series Convertible is planned for North American delivery in March, according to BMW.
The new 8 Series series predictably mirrors the look of the new 8 Series Coupé with a distinctive front end and muscular lines.
BMW claims that a total of 12.4 km. (351 L) of the roof space in place, even if it drops down during storage. In order to accommodate the rear seats to lengthy items, it split up and consisted of a 50:50 configuration to release the loading space.
The 8th gearbox will be sold from the start of the European sales in March with the selection of two engines: a 3.0-liter turbocharger in a 6-cylinder series. production of diesel engines 316 hp and 502 lb.-ft. (681 Nm) of torque at 1750 rpm in the 840d xDrive gearbox and 4.4L V-8 turbocharger with 523 horsepower and 552 lb.ft. (748 Nm) of torque at 1,800 rpm in the initial M850i xDrive Convertible.
Both engines feature a standard 8-speed automatic gearbox with torque transmission and a four-wheel drive BMW xDrive. The M850i xDrive also receives an electronically controlled rear differential lock, which is optional on the 840d xDrive Convertible.
BMW claims 4,310 lb. (1,956 kg) The 840d xDrive convertible accelerates at 100 km / h in 5.2 seconds and reaches a maximum speed limited to 250 km / h while at the same time achieving combined cycle fuel consumption of 46.1 mpg L / 100 km).
Despite weighing 132 pounds. (60 kg) more than his diesel siblings for £ 4,442. (2.077 kg), the M850i xDrive convertible is expected to reach 62 mph in just 3.9 seconds, reaching the same limited maximum speed of 155 mph, and returning a similarly modified fuel consumption in a mixed cycle of 7.5 l / 100 km.
Details of the United States report are still to be revealed.
The Coupe M8 is focused on competing with the Bentley Continental GT Speed, the Porsche Panamera Turbo and the Aston Martin DB11 at a price of about $ 150,000 in North America. The new four-wheel drive model has entered the final phase of development before the planned public debut in September at the Frankfurt Motor Show.
The M8, which will crown the newly revived 8 Series, will be sold with a choice of three different body styles. The first to come to showrooms in the UK will be the M8 coupe that took place this month in the Estoril circuit in Portugal.
After the second half of 2019, the M8 Convertible Set will be followed by the M8 GranCoupe four-cylinder module, which was also launched in the first half of 2020.
M8 is powered by the same petrol V-8 as M5. As with the engine in its four-door sibling, the twin-engine turbocharged engine that is longitudinally mounted will be offered in two different states.
In the standard M8 version, the 90-degree engine will be tuned to deliver more than 600 hp, says BMW M manager Dirk Häcker. For comparison, the M850i xDrive, which is part of the 8 Series, runs the less heavily-tuned version of the 4.4-liter V-8 BMW with a performance of 523 hp.
BMW did not publish the official performance data, but Häcker suggested that the M8 significantly undermines the 3.7 seconds claim for the M850i xDrive at 100 km / h. Combined cycle fuel consumption is set at 22.0 mpg (10, 7 l / 100 km).
In a move that reflects the latest M5 and M850i xDrive models, the M8 will receive a standard 8-speed gearbox as well as the fully variable xDrive 4-wheel drive system and an electronically controlled M differential on the rear.
Similarly, hanging is a dual tapered and multiple link system that uses M5. However, the M8 has a shorter wheelbase and wider tracks than its sedan siblings. The addition of hard measures within the body structure is more stringent than the M850i.
Häcker confirms that the new two-door vehicle will receive its own specific spring-loaded tuning, stretching springs and harder silencers than the M850i. It also gets revised bushings and rolls.
"We've focused a lot on body management, its horns are very flat and very small, so you're sitting much lower than the M5, so you feel a little different," he says.
Häcker also confirms that the new M8 center of gravity is 24 inches lower than the latest M5, and recalls that it boasts a 50:50 weight distribution, and partly by taking a lithium ion battery that weighs considerably less than the lead acid battery used in standard 8 Series models.
