Performance of the technology makes the, a pure artist, but may be an option with many cabin gadgets. Poor fuel economy limits their daily use, but we give the M3 a premium editorial choice.
As a manufacturer of luxury sports cars, the BMW is at the forefront of electronic navigation with 3D maps with high resolution, true high-fidelity audio systems and the integration of new smart phone applications. But the 2011 M3 Coupe tested by CNET emphasizes a different aspect of the BMW Performance gear technology.
Without some type of electronics in the cabin, this car was optioned to the track, with features such as Electronic Damper Control (EDC), a carbon fiber roof, and dual-clutch transmissions (DCT). And in the heart of all this is a 4-liter V-8 with a double-VANOS technology of BMW engines with direct injection and the innovative management.
The M3 can be performed even in the sedan and convertible forms, but the coupe body is ideal to introduce this technology to the service. The lack of rear doors and a retractable roof reduces weight and offers the possibility of carbon-fiber roof. Manually adjustable sports seats, electric seats are lighter, even if the car is still with practical belt Butler, automatically push the front seat belts on hand when you arrive by car.
Purists may laugh at all the material of high peak power, BMW M3 M3 because it provides the base with a manual transmission and a suspension fixed. But there is technique to get out of the M3 with 4-liter V-8 engines that push away from the past. BMW to suit all flow cylinder valves for controlling fuel, technology borrowed from the race. For an anti-knock sensors are used on candles to determine when knock occurs, and then adjust the profile of the power to stop him.
Compression produces a red line 8400 rpm and a power of 425 hp and 295 Nm of torque. Directed willing to increase efficiency. This engine delivers its power equally amazing, and gets the M3 to 62 mph in 4.6 seconds, according to BMW.
Despite the efficient engine, the M3 was not designed for fuel economy, so that his city and 20 mpg Highway 14 mpg gas guzzler tax gain feared. The car crashed just below this mark 14 mpg on the road difficult, although the M3 motorway CNET enough time contributed to an average of 15.1 mpg.
With the option of the M3 DCT is a very clean cabin, the little knob just above the console and has no clutch pedal. This shows a shift knob D, D, and plus / minus sign, but the S does not stand for the sport. Rather, it shows sequential manual gearbox. In practice, the same will not be necessary to change the F1 shift paddles on the steering wheel work with a precision of similar applications to take the changes in speed.
DCT BMW has seven gears and two clutches controlled by computers. Inside the transmission, the computer is constantly in motion, the coupling between the courses, which sit on or off the current cycle, with the gas and other factors determine whether you are probably up or down. The result is faster gear changes than ever to achieve with a manual. And with every change of speed is cracking down, because there is no torque converter.
The aura you feel the same car from the beginning, as a transition from neutral to drive, a push on the right side, and the manual mode by default. If you want to change automatically, you need to push back to the right. The harmony between the gearbox and the engine during the climb shows how the machine adapts automatically blips the throttle on the floor. Each blip product as a glorious roar of the engine that you climb.
A feature of DTC is not in vehicles with manual transmission, the gearbox is a rocker switch with the programs of the car works differently. The M3 has five training programs in automatic mode and six in manual mode. It also has a key to the Dynamic Stability Control (DSC) to change the profile. A Power button sharpens the throttle input to the console and optional EDC is another key to the console, you can switch between ride comfort, normal, sport and fashion.
The M button on the steering wheel functions as a PLC, so that bind you to a performance profile for them. As implemented, the M could stand for the macro. The M key is still in DSC mode sports, but you can also use one of the 11 behaviors, the nature of the EDC and the power that a profile of the preferred power available at the touch of a button on the steering wheel. Purists should not be self oscillating shaking knees, and dreams of simpler times.
