Sorte da Enzo que o motor é traseiro hehehee... |
Enzo não tem motor traseiro... Tem layout "Mid-Engine"...
"MR Layout
In Automobile design, an MR or Mid-engine, Rear wheel drive layout drives the rear wheels with an engine placed just in front of them, behind the passenger compartment. In contrast to the rear-engined RR layout the center of gravity of the engine is in front of the rear axle. This layout is typically chosen for its near-ideal weight distribution. The mid-engined layout does, however, use up a lot of space, making it impractical for any but two-seater sports cars. Though it is sometimes advantageous to have more weight in the rear, during cornering it makes entry a lot more difficult as the front tires have less traction, resulting in a slight understeer, and at the exit of the turn, the heavy rear tends to cause oversteer.
Early cars using the MR layout included the Zündapp Janus (1957), Lotus Europa (1966), Porsche 914 (1969), the Lamborghini Miura (1966), and the Ford GT40 (1966). The popularity of the term grew after Toyota used it on their MR2. Its space-inefficiency means that it is still only used in sports cars (or supercars) such as the Ferrari Enzo Ferrari, Honda NSX, Lotus Elise, and Pagani Zonda. Due to its near-ideal weight distribution, the MR layout is heavily employed in Formula 1 racing cars."

"RR Layout
In Automobile design, an RR, or Rear-engine, Rear wheel drive, layout places both the engine and drive wheels at the rear of the vehicle. In contrast to the MR layout, however, the center of gravity of the engine is actually past the rear axle.
This layout is typically chosen for a combination of several reasons. For optimal handling and to eliminate the phenomenon known as torque steer, the wheels which propel the car should not be the same ones that steer it. For optimum traction, the engine should be nearest to the driven wheels since the engine is typically the densest/heaviest component of the car. Thus, in a car which steers with the front wheels, it is better for the engine to be located in the rear of the car - either a RR or MR design.
The disadvantage of the RR configuration is that placing the engine outside the wheelbase creates significant problems for handling as, when the car begins to slide on a corner, the end of the car will tend to want to swing wide and overtake the front - especially under braking. This tendency is referred to as oversteer and creates potential safety issues in racing applications as well as for ordinary drivers on wet or icy roads.
In addition, even though the rear wheels benefit from the additional traction the added weight of the engine gives, the front wheels still need traction in order to steer the car effectively. For this reason, a RR layout car can also be prone to understeer. Most manufacturers have abandoned the RR layout apart from Porsche who has gradually developed their design with improvements to the suspension as well as electronic aids to reduce the shortcomings of the layout to acceptable levels.
Another manufacturer to implement the RR configuration was the De Lorean Motor Company with its DMC-12 sports car. To compensate for the uneven (65/35) weight distribution caused by the rear-mounted engine, De Lorean used rear wheels with a diameter slightly greater than the front wheels.
Early cars using the RR layout include the Tucker, the Volkswagen Beetle, the Porsche 911 and the innovative Chevrolet Corvair."
