Chrysler ME Four-Twelve Fastest Car

Chrysler ME Four-Twelve Concept

The spectacular quad-turbo, V-12 powered, mid-engine Chrysler ME Four-Twelve super car has roared onto the scene to shine as the most advanced Chrysler ever built.
The ultimate engineering and design statement, and a brilliant example of the Chrysler Group's capabilities, the ME Four-Twelve will establish a real-world performance record for a rear-wheel drive, mid-engine super car and may also set a record for lightening-quick vehicle development. Taking less than one year to complete from start to finish, the Chrysler Group partnered with some of the best in the business to assist in its development. There are a grand total of 11 people working on the ME from Chrysler (out of about 10,000 at CTC, FREC, and JTE), according to press preleases. There are a handful of suppliers-let's just say under 10 that have admitted in the public forums (at least in the trade magazines and press).

With regard to the transmission research and development, in my opinion the most important piece of R&D, Ricardo is handling the "bodies" (meaning the people or "warm bodies") doing the work, under Chrysler direction and supervision. Approximately 30 people (2 from DCX, maybe ) would be involved with this work, including design, engineering, manufacturing feasibility, testing, and process.

History

chrysler ME 412 car pictureAccording to Deutsche Press, around 300 Chrysler ME 4-12 were to be built each year, largely with carbon, aluminum, and other light-weight metals. Road testing was scheduled for late January 2004, with production rumored to start within two years. The car itself was being built in the United States by Metalcrafters, and we have been told that the lead engineer is from Chrysler and the lead suppliers from North America - and that this was the outcome of battles with Stuttgart, which wanted to use European suppliers and engineers. Most off the shelf parts appear to be from Chrysler aside from the engine. The transmission seems to be based on Chrysler, Mercedes, and other designs.The ME Four-Twelve braking system features massive 15.0-inch (381 mm) ventilated carbon ceramic composite disc brake rotors with six-piston aluminum mono block calipers for superior braking performance during all driving conditions. The composite discs are sixty-five percent lower in weight than comparable cast iron rotors. Wheels are cast aluminum: 19x10-inch front and 20x12.5-inch rear. Michelin high-performance radials are 265/35ZR19 in the front and 335/30ZR20 in the rear.

chrysler ME 412 car pictureAt just 44.9 inches tall, 78.7 inches wide and 178.8-inches long, the two-seat, mid-engine ME Four-Twelve was wind tunnel tested in Auburn Hills. The computer controlled active rear spoiler articulates rearward 100 mm to increase down-force to a total of 925 lbs. (421 kg) at 186 mph (300 km/h), while achieving a competitive coefficient of drag (Cd) of 0.358. All body openings have been optimized to achieve maximum thermal performance. Large vented front and rear wheel houses reduce lift as well as active and passive aerodynamic devices that have been implemented to provide stable vehicle performance at all speeds.

The interior is relatively spacious with 37.2 in (942 mm) of headroom, and 42.7 in (1085 mm) of legroom. A large glass roof panel extends from the windshield to the rear header. Passenger-side adjustable foot support helps keep the co-pilot in position during extreme cornering maneuvers.This vehicle breaks the mold of the super car genre because its packaging can easily accommodate drivers in a wide range of heights. Ease of access to driving controls was a primary focus. For example, there are steering wheel mounted controls, chrysler ME 412 car pictureincluding a column mounted F-1 racing style paddle shifter with aluminum shift paddles and centrally mounted driver controls.

Styling was done by a young and friendly Chrysler designer, Brian Nielander, who normally designs trucks; he worked directly with engineers and aerodynamics experts to shape the interior and exterior and make sure that the engineers did not make the ME-412 uncomfortable. Wolfgang Bernhard, Chief Operating Officer - Chrysler Group, said, "It's everything we—ve learned about creating exciting, desirable automobiles. And, as such, it's not really a concept car but is, in fact, a prototype that will be road-ready by summer."

Technology

chrysler ME 412 car pictureWith a curb weight of just 2880 lbs. (1310 kg), the ME Four-Twelve has the weight-to-power ratio of 3.4 lbs/bhp — a new performance record. In actual Chrysler speed runs, the ME Four-Twelve goes from 0-60 mph in 2.9 seconds, 0-100 mph in 6.2 seconds, and it will blister through the quarter mile in 10.6 seconds at 135 mph. The estimated top speed of the ME Four-Twelve is 248 mph (400 km/h). The vehicle is designed and packaged to achieve outstanding thermal performance under extreme operating conditions. Its large capacity, high-efficiency engine-cooling system allows this engine to retain optimum thermal performance — a key advantage in the super car arena.

The 7-speed Ricardo Double Clutch Transmission was developed specifically for this vehicle and features the latest double wet-clutch technology and electronic control strategy. The exclusive transmission delivers uninterrupted torque to the rear wheels with 200 millisecond shift times. The double wet-clutch technology appears to come from Chrysler. (An anonymous Chrysler employee wrote, "I cannot believe that Chrysler didn't get the credit for this transaxle!!! To be fair, it fits with its replacement by the junk MB controls and system.")
