Manufacturer of specialized in various engine camshafts
It has been more than 100 years since the first naturally aspirated V12 engine came out, but now it has come to the edge of the historical stage. Even so, some manufacturers are still obsessed with pursuing its limits.
Some people have speculated that the Ferrari 812 will be the last Ferrari model equipped with a V12 self-priming engine? In any case, Ferrari clearly has no plans to let the 812 exit in a low-key manner. Yesterday, Ferrari launched two 812 special edition models, namely the hardtop 812 Competizione and the Targa convertible 812 Competizione A.
Competizione is Competition in Italian. This suffix has been used many times in the history of Ferrari and can be understood as a competition version. So how 'competitive' are these two models?
The maximum power of the 6.5-liter self-priming V12 engine reaches 830 horsepower, which is 30 horsepower more than the 812 Surperfast. The maximum speed is increased from 9000rpm to 9500rpm, and the maximum power needs to be reached at 9250rpm. However, the engine torque is slightly reduced, from 718Nm to 692Nm.
The weight of the titanium alloy connecting rod is reduced by 40%; the piston pin and camshaft are coated with diamond-like carbon to reduce friction loss; the crankshaft has been rebalanced and adjusted, which is less than the previous version 3% weight; the variable geometry inlet system has been redesigned, and the size of the intake manifold and air collecting box is smaller to shorten the total length of the inlet and ensure the air supply at high speeds.
All air intake passages are integrated in a larger front single air intake, and the cooling efficiency is increased by 10%. The engine oil tank has been redesigned and matched with a variable flow oil pump. While the oil supply speed is increased by 30%, it also reduces the amount of oil by 1 kg.
It is still equipped with a 7-speed dual-clutch gearbox with the same gear ratio, but the shift speed has increased by 5%. The zero-hundred acceleration time of the 812 Competizione is 2.85 seconds, which is only 0.05 seconds faster than the 812 Superfast, but the acceleration time of 0-200km/h is shortened by 0.4 seconds and is now 7.5 seconds.
The 812 Competizione has reduced weight by 38 kg (1487 kg), which mainly involves the power system, transmission and body structure. Carbon fiber materials are widely used in the appearance of new cars, especially front and rear bumpers, rear spoilers and air intakes. The four carbon fiber wheels are 3.7 kg lighter than forged wheels.
The 812 Competizione has a more powerful aerodynamic design, and the operating temperature of the brake system is reduced by 30 degrees Celsius, which can cope with more intense track driving. The air intake on the side of the headlights has been eliminated and replaced by an engine cover in the form of 'blinds
The rear window has also become a 'blind'. This design can further increase downforce. With a larger rear spoiler and diffuser, the rear of the 812 Competizione The downforce is 35% higher than that of the 812 Superfast. But this also makes the rearview mirror in the car basically a decoration.
Because it is equipped with a gasoline particulate filter to meet higher emission regulations, 812 Competizione has redesigned the exhaust system and eliminated the muffler to compensate for gasoline particulates. The noise of the filter loss. The position of the exhaust tail throat was moved to the ends of the diffuser and became a part of the diffuser.
The 812 Competizione is the first Ferrari model equipped with a four-wheel independent steering system. Unlike ordinary four-wheel steering, the steering angle of the left and right rear wheels can be independently controlled . In addition, it is also equipped with the 7.0 version of the vehicle sideslip angle control (SSC) dynamic system, which includes electronic differential (E-Diff 3.0), traction control (F1-Trac), SCM-Frs magnetorheological suspension control, dynamic Strengthen the system FDE and many other complex electronic systems.
As for the Targa convertible version of the 812 Competizione A, no specific specifications have been announced yet. The engine should be the same as the hardtop version, but the body will be heavier. The acceleration may be slower. But who cares? Just look good.
Two special edition models will be sold in limited quantities, of which the 812 Competizione is limited to 999 units. The price must be very expensive. However, as the current pinnacle of the Ferrari V12 model, and I don't know how many V12 models will be available in the future, this Prancing Horse must not lack Bole.
