Who is stronger, BMW M3 GTR or Audi R8?

"BMW M3 compares Audi R8 and Chevrolet Corvette C6"

● Combination test vehicle:

Audi R8309kW, four-wheel drive, 0- 100km/h acceleration time of 4.4 seconds, top speed of 30 1km/h, price of 104400 euros.

BMW M3 309kW, rear-wheel drive, 0- 100km/h acceleration time of 4.8 seconds, top speed of 250km/h, price of 66,650 euros.

Chevrolet Corvette C6 297kW, rear-wheel drive, 0- 100km/h acceleration time of 4.8 seconds, top speed of 300km/h, price of 65,290 euros.

Maybe you will ask: Who is the real rival of BMW M3? Just like your answer, it's actually very simple: Audi RS4 and Mercedes-Benz mercedes benz c AMG. Unfortunately, M3' s two real rivals at the same level are undergoing some changes. The old Audi RS4 has been discontinued and the new successor has not yet been put into production. Mercedes' new C63 AMG can only be sold next year, so we can't find a real rival for BMW M3 now.

However, it doesn't really matter, because according to Munich people's own slogan, "The new M3 actually doesn't need to hide in front of the real sports car"-in the face of such a loud battle declaration, there is no reason for us to avoid it. We might as well take this opportunity to find two "purebred sports cars" for M3: one competitor is R8, also from Audi family, equipped with V8 engine, with the maximum power equal to M3-the other competitor is Corvette C6, an American classic sports car with the same price as M3, also equipped with V8 engine, with the maximum power of 297kW.

"Sports Attitude of BMW M3"

The three cars are not only different in appearance, but also very different in the technical scheme of body manufacturing: Audi space frame is applied to R8, and a large number of ultra-high pressure forming all-aluminum profiles and casting and welding technology on the body make R8' s body have excellent rigidity; BMW, the rival of Audi R8, also used aluminum metal in M3 body manufacturing, but it didn't adopt all-aluminum structure-the pressure-bearing parts and load-bearing parts of BMW M3 are all steel structures, and the external parts of the body are made of aluminum metal (hood), artificial organic materials (fender) and carbon fiber plate (top cover) respectively; Corvette's body structure is not simple. As the main pressure-bearing structure, the body bottom plate is made of steel supplemented by special fiber materials, the instrument panel structure bracket is made of aluminum alloy, and the body cover is made of artificial organic materials.

In addition to the differences in appearance, the internal space layout of the three cars is also very different. The biggest difference is that Audi R8 and Corvette C6 are both two-seat sports cars, while BMW M3 adopts four-seat design. Judging from the size of the car, the front row space of M3 is the most abundant, mainly wider than the other two cars, and the seat itself is not as narrow as the opponent's; In addition to the small size of the car body, the power transmission channel through the hall in the car also affects the spatial level of Audi and Corvette.

Besides, R8' s suitcase is not very spacious. The trunk is located in the front of the car body, and its volume is only about 65,438+000 liters. In addition to the normal suitcase, there is about 90 liters of space behind the seat, but even if the two add up, the space is still far from enough for long-distance travelers. Compared with R8' s "pocket suitcase", M3' s trunk is very spacious, reaching 430 liters, completely reaching the level of ordinary family cars. Corvette, on the other hand, inherited the "fine tradition" of typical American cars, and the trunk volume reached 634 liters-basically only two people in the car could travel long distances with all their belongings.

When it comes to the function and operation design of cars, Audi is still a model of many cars. The operation setting is simple, which completely conforms to our natural logic thinking. All the buttons and knobs are within reach and neatly arranged. Compared with Audi, M3 has basically the same function settings. Obviously, BMW's car designers fully draw lessons from the gains and losses of various cars in the family. M3 operation embodies the principle of practicality first, and its logic is clear. The only thing that puzzles us is M3' s i-Drive system.

It is a trouble for first-time driving: if you want to set the dynamic characteristics of M3 according to your own taste, you must search hard in the i-Drive system, but it also has its advantages, that is, after the setting is completed, the system can store its preferred parameters, and the next adjustment can be directly retrieved by the "M" key on the steering wheel; There is something special about Corvette C6, which we don't quite understand: If we forget to put reverse gear after parking, the battery will be dead the next morning-this is their design-and we can only turn off the electrical appliances on the car if we put it in gear.

In terms of security configuration, Corvette from the United States once again played a failed role. Compared with everything in BMW M3, C6 lacks many safety configurations, and it is also very different from Audi R8. The workmanship quality of the Audi R8 is the best among the three cars, and every point and place looks very exquisite-this is a matter of course, because the Audi R8 is 40,000 euros more expensive than its competitors in terms of price alone, and exquisite workmanship is not extravagant; M3' s workmanship is also very good, but there is still a gap between M3' s material selection and other competitors. Compared with two German cars, Corvette is a little embarrassed in workmanship and material selection, and there are still some "low-level defects" in expensive sports cars, such as lax matching between parts, frequent abnormal noise during driving, and cheap material selection, which have seriously affected C6' score in this chapter.

Corvette's rear axle adopts the design of transverse leaf spring, which brings great trouble to its comfort test, especially on the continuous and slightly wavy road section, C6' s performance is poor, the rear end is not very stable, and the vibration of the road surface is directly transmitted into the car, as if there is no filter at all; Corvette's front axle is easy to cause the body to move, and the vibration filtering of the road surface is not ideal. The steering system has a similar problem. When the road is uneven, the steering wheel feels like a thug.

Audi R8

The chassis is also tough, but it is by no means "hard enough to make you fidget". R8 is very effective in filtering road bumps and has a good sound insulation effect on driving noise. Although you can always feel the working sound of V8 engine in the middle position of the car body during the whole driving process, it will never provoke your nerves; The side support of R8 seat is very powerful and can be adjusted at will. People of any size can find their own suitable position, which is suitable for long-distance driving and is not easy to feel tired.

BMW M3 is more comfortable. Even if the road is bumpy, you won't feel that M3 is a sports car that has made many adjustments in pursuit of sports performance. The chassis characteristics of M3 can be switched freely, and can be adjusted between comfort and sportiness. Compared with the Audi R8, the side support of the M3 seat is slightly softer.

Each manufacturer's engine has its own characteristics, which we can clearly feel in these three cars. Although these three engines are also called V8, their personalities are quite different. As we expected in advance, the V8 engine of BMW M3 has outstanding high-speed performance, and the highest speed can reach 8300 revolutions per minute, which is all the power source of M3-it is estimated that this alone is enough to make those who still miss the previous generation of 6-cylinder old BMW no longer feel sad.

The cooperation between M3 transmission and engine can be described as seamless, and the transmission can fully release the deep power of the engine no matter what gear it is hung in. M3 engine has good throttle sensitivity, and slight toe movement can be immediately converted into crazy speed increase: from getting rid of the static state to100 km/h/h.

BMW M3 only takes 4.8 seconds, and M3 can break through the 200km/h mark after 15.7 seconds. The maximum speed of M3 is limited to 250km/h by electronic speed limit, but this can be changed according to the customer's own wishes-M-Drives package with a price of 2,450 euros is added for M3, so that M3 can soar to 280km/h without any electronic limit.

In terms of the efficiency of converting engine power into driving force, neither opponent can surpass BMW M3, which is not entirely due to the engine itself. The transmission and shifting mechanism seems to be tailor-made for the engine, and the comprehensive factors have created the excellent performance of M3. Of course, the "uneconomical" fuel consumption is generally hidden behind the excellent performance, and M3 is no exception: every 100 km, M3' s fuel nozzle will spray 14.6 liters of gasoline, and if you are not careful, you will get worse results. It is very easy to burn 65,438+08 to 20 liters of gasoline per 100 kilometers.

"Interior and Engine of Chevrolet Corvette C6"

Compared with BMW M3, Corvette's 6-liter engine is economical, and only 13.7 liters of gasoline can drive it 100 kilometers, and Corvette's requirements for fuel quality are not as harsh as M3. But in the same way: it is an indisputable fact that relatively low fuel consumption also hides low dynamic performance; The first gear of Corvette is only suitable for starting, and it feels that the car can directly shift to the sixth gear-the engine starts again at a very low speed, but this is not a problem, because the C6 V8 engine can output the maximum torque of 546Nm, which is more powerful than competitors (Audi 430Nm, BMW 400Nm) to drive the whole vehicle.

Compared with abundant torque output, Corvette's engine doesn't seem to like climbing to high speed. You need to shift the transmission to the next gear every 6000 rpm, otherwise you will obviously feel the fatigue of the engine. Nevertheless, if we can control this Corvette well, it can accelerate like M3, and it only takes 4.8 seconds to break through 100km/h, and it is even faster than M3 from getting rid of standstill to breaking through 200km/h; Its maximum speed is 300km/h, which is only a little slower than that of Audi R8, but please note that there is still a difference: although the maximum speed of the two cars is comparable, R8 is much lighter than C6 in the whole acceleration process.

Audi R8 has been keeping a brisk pace. This super sports car with a mid-engine can complete the acceleration process from standstill to 100km/h in 4.4 seconds, and it only takes 15.2 seconds to accelerate to 200km/h, which is also the fastest among the three cars. The shift operating mechanism of R8 is not as smooth as BMW M3, but it is much more accurate than Corvette. Driving R8 requires the driver to shift gears harder, but this does not affect the driving experience. It can be clearly felt that the cooperation between the transmission and the engine is very harmonious during driving. However, excellent acceleration performance is naturally at the expense of ultra-high fuel consumption. R8 gasoline direct injection engine consumes 65,438+05.7 liters per 100 kilometers, which is another disadvantage besides the basic purchase price. Tail comparison between BMW M3, Audi R8 and Chevrolet Corvette C6 "

We were deeply impressed by the performance of Audi R8 and BMW M3 in handling and testing. Their speed in detours is amazing, but in comparison, M3 is slightly better: in detours, rear-wheel drive beat full-time four-wheel drive. M3 differential lock can realize 100% differential distribution, which can better offset the negative impact of wheel slip. The rear of the car releases too much kinetic energy through gentle steering to keep the car body as stable as possible.

The steering system of M3 is accurate and easy to control, which is very prominent in the test around piles. Its fastest speed around the pile reaches 70.4 km/h, while R8' s highest speed is only 66.8 km/h, but R8' s time consumption in the control test is still shorter than M3's. When the electronic stability program is closed, R8 can maintain a stable posture, and it is difficult to break through the physical limit. However, when R8 continuously changes direction, the tail reaction is very strong, which needs the driver's attention. Compared with its two rivals, Corvette lags behind, its steering system lacks accurate feeling, and its braking performance is also insufficient for such a high-performance sports car. In addition, the grip of the wheel is also very general, which is very different from the opponent.

Corvette scored five best results (basic price, insurance rate, insurance cost and fuel consumption cost) in this chapter, which helped Corvette beat BMW M3 at the same price. M3 only achieved advantages in environmental protection; Audi, on the other hand, suffered the highest base price and fell to the end, but the vehicle warranty and standard configuration level are the best.

"dashboard comparison of three cars"

BMW M3 won the final victory, not only because it performed well in the whole test today, but more importantly, it is the most suitable car for daily use. Munich people have long wanted to combine family cars with super sports cars perfectly. The success of M3 today shows that they have turned their dreams into reality. The high price and the lack of spacious interior space dragged down Audi's performance. R8 finally won the second place, but R8 showed perfect dynamic performance. From the visual point of view, R8 is a beautiful work of art, which makes the opponent far behind. Corvette, who came last, was actually not bad. Its powerful engine and lowest price are its attractions.

Audi R8:

R8' s V8 direct injection engine was born out of Audi RS4, and it didn't adopt turbocharging technology, and its maximum power reached 309kW. Different from ordinary RS4 engine, R8 V8 engine adopts dry oil pan lubrication system, and each cylinder is still designed with four valves, which are driven by two camshaft chains. This engine has a deep cylinder block and adopts variable timing technology. Through direct injection technology and large compression ratio, the efficiency of the engine has been well improved. The engine cylinder block is made of aluminum-silicon alloy, and the piston ring is also made of special materials, which can effectively protect the friction surface between the piston and the cylinder wall. "Wheel hub comparison of three cars"

The maximum power of BMW M3 engine also reaches 309kW, which is consistent with the V 10 of BMW M5 in many technical details. The cylinder of the engine is very shallow, and the design pays great attention to the performance at high speed. Many advanced technologies of BMW are integrated in it, such as efficient air distribution and fully variable timing adjustment (Doppelvanos). The movement of a single throttle is controlled by a stepping motor, which greatly improves the throttle sensitivity of the engine. Compared with R8' s dry oil pan lubrication system, BMW M3 adopts a common lubrication system driven by two oil pumps, which can fully meet the lubrication requirements.

Structurally, this 8-cylinder engine with a maximum power of 297kW is completely an "outdated" work. Design does not pursue high speed, but pays attention to displacement; Engine timing adopts camshaft design with push rod, and the top of cylinder is narrow and light; Thanks to the progress of application technology (materials, light metal shell, valve distribution technology and engine electronics technology), this 6-liter engine has also achieved good performance, especially in the torque output of low-speed range, which is more fuel-efficient than competitors in actual driving.
