The ME stands for "mid-engined." The quad-turbo, V-12 powered Chrysler ME Four Twelve supercar may not only establish real-world performance records but may also set a record for lightning-quick vehicle development. It took less than one year to complete from start to finish (though we don't know what they started with).
The engine is from AMG, with 850 bhp @ 5750 rpm, with 850 lb-ft. (1150 N-m) of torque between 2500 and 4500 rpm on premium unleaded fuel. It was reportedly designed for Chrysler, but will probably be used by Mercedes in other applications (we'd expect it to appear in the Vision and perhaps the McLaren SLR). Use of the AMG engine was dictated largely by the need for high power with light weight (around 500 lb) and at reasonable development cost.
With 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.")
