[ĐÁNH GIÁ XE] McLaren 720s – Black Swan

Let’s compare McLaren 720s with competing supercars about chassis structure. Currently, only Lamborghini Aventador has a monocoque chassis like the 720s, but the Italian supercar weighs 300 kg more than the 720s. Lamborghini Huracan has a hybrid chassis with aluminum and carbon fiber, to be more precise, only the engine wall and the middle part of the car floor is made of carbon fiber. Every supercar in the segment of Ferrari has an aluminum chassis.

The chassis of the 720s has excellent torsional rigidity and durability. McLaren engineers have revealed that the first generation MonoCage chassis of the 650s has enough torsional rigidity to attend the GT3 racing formula without the need for an additional anti-roll frame. Of course, they still have to add this detail to their cars to qualify for the race because the anti-roll frame is a must-have component. You want to know how hard the main frame of 720s is? Each column A of the 720s can withstand up to 3.3 times the weight of the car before being deformed, ie 4.2 tons!

Compared to its predecessor 650s, the practicality of the 720s is also superior. The McLaren 720s has a MonoCage 2 frame that is both lighter and has thinner A and B C pillars, a smaller door sill than the 650s. That makes getting in and out of the car easier and visibility for the driver is also more open. If you’ve ever sat in a Lamborghini Huracan, you will see how limited the visibility of a mid-engine supercar can be. However, the glass frame design of the 720s teardrop-shaped windows offers an extremely clear view, perhaps the most airy in the segment.

Even the C-pillar is hollowed out in the middle to give a clearer back vision. This is a big plus for those who want to use super cars on a regular basis. The MonoCage 2 chassis is not only beautiful but also extremely safe. Two aluminum subframe parts make up the front and rear. These two subframes are much softer than the middle carbon frame. Of course when I say soft, I mean it is less hard than carbon fiber McLaren uses aluminum alloy hardness is also very optimal. The mission of the subframe is to absorb the impact force when an accident occurs, the person sitting in the cabin will be unharmed.

The McLaren 720s has a dry weight of just 1,283 kg, the lightest in its segment. It is much lighter than the Lamborghini Huracan, Ferrari 488 GTB or Porsche 911 Turbo. To make it easy for you to imagine the horrors of the McLaren 720s supercar, I have the following comparison: it’s lighter than Hyundai i10 167 kg but 9 times stronger! The McLaren 720s is also 18 kg lighter than its 650s predecessor.

Not only the chassis, but also the hardware and software of the McLaren 720s suspension system is also very special. McLaren calls this suspension Proactive Chassis Control II. This system is a big step up from the first generation Proactive Chassis Control. This is the result of 5 years of cooperation between McLaren engineers and Cambridge University. Basically, the McLaren 720s still maintains a double-arm suspension system on all 4 wheels, 4 dampers are connected diagonally from left to right, from front to back with special oil pipes. Compared to the original PCC, the second PCC uses 12 more sensors, including 4 acceleration sensors placed in 4 wheels and 8 pressure sensors placed in the dampers. The central computer analyzes all data from the sensor system that adjusts the damping of each wheel 500 times per second to help the 720s cornering with near-perfect stability and balance, as well as Great smoothness when walking in the city.

Currently, there are quite a lot of suspension solutions to create the smoothest and sporty driving experience possible. We have 3-chamber air suspension, electric control stabilizer bar, suspension that can sweep the road front to change the stiffness of the damping bar etc. However, for me, the hydraulic suspension The force of the McLaren 720s is superior because its operating principle is much simpler, purely mechanical than the solutions of Porsche or Mercedes-Benz. It is less dependent on electronic systems than the modern suspension systems of leading German car manufacturers, so it will probably be more durable and less damaged. Have you heard the scary story of the flat balloons that made the car “be” lowered reluctantly like the Liberty Walk?

McLaren’s Proactive Chassis Control II operates on very simple, at least theoretical principles. That is the principle of pressure. Each shock absorber on 4 wheels has 2 oil chambers, they are connected diagonally from left to right, from front to back by oil pipes running under the floor of the car. Other important parts of this hydraulic suspension system are 4 spill tanks located next to the dampers, the effect of which is to let the oil in the temporary pipe “stay” when the oil pressure is too high. They look like bubbles of fish!

Besides, the most important thing in deciding the suspension of hard or soft 720s is the 8 throttle mounted in the dampers. Their mission is to coordinate the rate of oil transfer between the dampers. Simply put, if the rotation speed is fast, the oil from the left shock can freely move to the right one, then the McLaren 720s suspension will be “soft”, smooth and most comfortable for onions. guest. Conversely, if the speed of rotation is slow, the suspension will be “hardest”, providing the ability to control the body and anti-tilt when cornering, as well as anti-dipping when braking or lifting the car when accelerating well Best.

The remarkable thing is that McLaren can create such completely different personalities in 3 modes of Comfort, Sport and Track with only 8 throttle valves! Inside each damper are diamond-shaped stoppers that can move forward. When the driver selects 3 modes of Comfort, Sport and Track, the stoppers are pushed up or down to coordinate the oil standard rotation speed. Really, this is a very simple but extremely effective system. I personally find it more enjoyable with the McLaren 720s suspension than any other system.

Experience beyond all standards

Theoretically, the McLaren 720s Proactive Chassis Control II suspension is too simple to deliver the desired effect. However, practical experience shows it extremely effective. The super hard carbon chassis is the perfect platform for the suspension system to “dance”, neutralize all potholes, live buffalos in the road area near My Dinh yard, which is currently very bad road surface due to construction of the track. F1 next year. Personally, I have never driven a super low-profile supercar yet as smooth as McLaren!

In fact, the British car company is not too exaggerated to say that you can use 720s daily. Although you still sit extremely low compared to the road surface, but thanks to the carbon fiber frame, the A and B columns are very thin, providing extremely clear view, superior to Lambo or Ferrari. The ultra-wide vision like McLaren’s IMAX screen is completely different from other supercars in the same range. But unfortunately the rearview mirror in the car is still a thick border that looks quite lost, it would be better if the British car company fitted a borderless mirror for this supercar.

Another difference that I noticed is that the brake pedal is extremely hard 720s, you have to use a strong force to pedal enough to stop the car. This hardness is actually a plus if you spend time getting used to it. The pistons on the four wheels respond instantly and gradually to the slightest movement of the brake pedal and give the driver a sense of confidence. According to McLaren, the hardness of the brake pedal is to simulate the brake pedal of the racing car. This is also an interesting point about the British car company’s philosophy of making cars.

McLaren 720s has 3 driving modes: Comfort, Sport, Track and Variable Drift Control feature very interesting. It allows the driver to choose the intervention of the electronic balancing system and select the angle at which the tail of the vehicle can bounce off, up to a maximum of 35 degrees. McLaren 720s and Ferrari 488 GTB are the only two supercars in the segment that retain oil power (even the Ferrari F8 Tributo and 812 Superfast have switched to electric power). Oil-assisted steering is extremely important, helping you enjoy true driving even at low speeds.

Even Pirelli P Zero Corsa tires have been developed specifically for McLaren 720s. Although these are high-performance tires, they still add a very thick layer of foam on the inner tire. This foam layer works to reduce tire noise coming into the cockpit. Pirelli’s tire technology is equivalent to Continental’s new ContiSilent technology for the new Bentley Mulsanne and the Tesla Model S. According to Continental specifications, this tire can reduce noise by 9 dB compared to conventional tires, Pirelli. then there is no specific number published. It should be noted that only Pirelli P Zero Corsa tires on the 720s are noise-proof foam, not on other supercars. This set of tires offers 6% better mechanical grip than the 650S.

McLaren 720s owns a 4.0L dual-turbocharged V8 engine that is almost entirely new. The McLaren 720s 4.0L V8 engine produces 720 horsepower and 770 Nm of torque. Thanks to the ultra-light design, 720s reach a capacity / weight ratio of up to 561 hp / 1 ton, the best in the segment. This ratio of Ferrari 407 horsepower / 1 ton, of Lamborghini Aventador is 492 horsepower / ton. And Kia Morning’s is 80 horsepower / 1 ton. Yes, you have to compare with popular cars to see what the super cars eat together!

According to the company documents, the McLaren 720s needs 2.9s to accelerate to 200 km / h and only 7.8s. For comparison, the Aventador SV accelerates from 0-200 km / h in 8.6 seconds, Ferrari 488 GTB from 0-200 km / h in 8.3 seconds. Ford Mustang EcoBoost to 200 km / h in 30 seconds, Kia Morning to 200 km / h in …, oh forget, the maximum speed of Kia Morning is only about 160 km / h. McLaren 720s brakes from 200 km / h to a stop in just 4.6 seconds with a distance of 117 m. Ceramic – carbon brakes are standard equipment on McLaren 720s.

Compared with the 3.8-liter engine of 650s, the engine of the 720s is 120 mm lower, helping to lower the center of the car, thereby improving the overall performance because the engine is the heaviest part on a car, any motor vehicle. The lower the center of gravity is also lower, which helps the car into a more stable cornering. The roof of the 720s has a mostly carbon fiber structure, which also helps the focus of the 720s to be 3% lower than the 650s. The McLaren 720 has 2 twin-scroll turbochargers placed between the two cylinder walls to reduce hysteresis. The turbochargers on the McLaren 720s can rotate at a speed of 160,000 rpm and have electric pressure relief valves that are electrically controlled instead of only driven by pressure differences.

However, the specifications on the paper cannot describe how this supercar accelerates. Every time I stepped on the gas, I felt like I had just activated a time gap and both myself and the car were being pulled forward by an irresistible invisible force. The lightweight, combined with 720 horsepower that makes acceleration possible is just a little less than the million dollar hypercar! The car accelerated too fast, too fierce so I accidentally discovered 1 more small disadvantages of it. It’s the McLaren logo embossed in the headrest so hard that my neck hurts every time the car accelerates!

Needless to say, you can also understand that the acceleration of the 720s is superior to the Ferrari 488 GTB or Lamborghini Aventador. Although the engine of the 488 GTB responds a bit faster, with a little more booster delay than the 720s, while the Aventador gives the most intense roar, in terms of overall experience, the McLaren 720s is still superior. It is quieter when needed, gives more open space and especially the performance of the British supercar still overwhelms the Italian rivals.


It’s hard to believe that the 720s is just the standard car of the McLaren Super Series. Since the “base” version has had such a terrible performance, I can’t imagine how the new 750LT model will be released soon! While there are still a few small drawbacks, the McLaren 720s has certainly set a new standard for its segment. I mentioned the image of a black swan at the beginning of the article which implies that McLaren always does something different from the majority. Now, the 720s, 600LT or Senna have become the standard of the supercar segment and the majority have to pursue cars with British nationality.
