Technical analysis of test drive Alfa Romeo Giulia

Introduction: What should come will come eventually. Alfa Romeo Giulia really came this time, because I tested the China version of Giulia at the Italian Balocco circuit. These include 200 horsepower and 280 horsepower models. These two cars have a real feeling, which is totally different from those currently on sale, such as BMW 3 Series and mercedes benz c Class. Of course, during the test drive, I also briefly experienced the European version of Giulia QV four-leaf clover, which is the new Borgling model that runs for 7 minutes and 32 seconds. It's really exciting. However, this test drive is mainly aimed at China models with 200 horsepower and 280 horsepower, which can directly tell you whether it is worth looking forward to and whether it is worth buying.

What does Julia have? Black technology? Blessing?

Based on the relationship between Alfa Romeo, Ferrari and Maserati, which belong to FCA Group, Giulia enjoys Ferrari and Maserati in many aspects, such as design, power technology, research and development, and even their research and development centers are together to form a super-running group. Giulia has a perfect body weight ratio of 50: 50, an ultra-low drag coefficient of 0.25cd, and an ultra-light body, which is also the first four-door rear-wheel drive model of Alfa Romeo and the most powerful product of Alfa Romeo since 1986. Everything is optimized to improve processing and performance.

Exclusive patented suspension system

Giulia's front suspension is a double wishbone structure, and a unique patent-virtual steering shaft technology (there is no detailed information for technical explanation at present) is added, which can make the tires almost completely perpendicular to the ground in any state, make the whole vehicle have better grip, improve the directional response speed by 20%, and realize fast and accurate steering control. The rear suspension is a modified double wishbone structure based on the Maserati rear suspension, with smaller volume, better mobility and comfort, and a limited slip differential.

The whole system comes standard with soft and hard adjustable suspension.

This pause can be regarded as? The CDC took the initiative to hang? In the upgraded version, the four suspension hardware and software are quickly adjusted based on hydraulic pressure, and the whole response time only takes 10ms, so Giulia's chassis feels very good, comfortable at low speed and stable at high speed. In addition, this suspension has a very powerful control system. For example, when accelerating or starting, the rear suspension will instantly harden and suppress the posture of the front of the car; When braking, the front suspension will instantly harden to resist the nodding posture. When turning, the suspension on the outside of the curve will be hardened separately to resist the inclination of the car body, that is to say, all four suspensions can be adjusted independently to control the driving attitude of the whole car, so that the attitude such as rolling and nodding can be controlled within a very reasonable range, which brings good support to the control.

The lightest car in its class.

Giulia is made of aluminum in many places, such as the hood, doors, fenders and lower arms. Coupled with carbon fiber transmission shaft and other equipment, the weight of a 200-horsepower model is only 1.429kg, which is very rare for a luxury model with a wheelbase of 2820mm, and it is nearly 200kg lighter than the BMW 328Li. It is very helpful to lose weight by moving forward. In addition, this model has the best crash performance in Europe in 20 16, and has the highest score in pedestrian crash test, and its safety is not bad at all.

The most powerful braking system in the world

Giulia is equipped with IBS lightweight integrated braking system. Alfa Romeo's unique braking system can quickly improve the braking speed, and the actual braking experience is better and more direct than traditional braking. The normal brake distance is less than 38 meters, while the high-performance brake is equipped with carbon ceramic wheels. The test result is less than 32 meters, which can be said to be the strongest level in the industry, even more powerful than a number of super-running braking systems.

The fastest automatic transmission in the world?

The 8-speed automatic manual transmission from ZFZFZFZF is the fastest automatic transmission in the world at present, and the fastest complete shift time is less than 100ms, that is to say, it takes less than 100ms from pressing the shift paddle to completing the shift, while the complete shift time of V8 models in Masarati is 100ms, too. In addition, the shifting mode of the gearbox can be changed according to the driving mode. For example, when the driving mode is fierce, it can bring strong shift impact and exciting acceleration, that is, use the full shift speed within100 ms. In the case of low speed or daily driving, the shift will become silky smooth, which is not unrelated to the harsh requirements provided by Alfa Romeo when customizing ZF's transmission.

DNA-driven mode

Compared with other models, the driving mode adjustment of Romeo's DNA gene will involve as many as 15 body parts. For example, in addition to the components that must be adjusted, such as engine, transmission and suspension, braking, dynamic steering, turbocharging, exhaust system, torque vector distribution, four-wheel drive, ES P, ASR, brake lights, cruise control, intelligent air conditioning and lubrication system, there will be targeted adjustments, which will be used for reference. Where d stands for dynamic sports driving mode, which provides the greatest driving pleasure, but ESP cannot be completely turned off. N is the natural daily road driving mode, and A is the advanced E-efficiency energy-saving mode. In addition, the top QV four-leaf clover also provides a competition mode. Electronic programs such as ESP are completely closed, and only a few electronic systems are involved. Suspension and throttle are in the most tense state, pursuing a pure driving experience.

In terms of power, the China version of Giulia is basically consistent with the information previously exposed. The 2.0T model is equipped with two versions of high and low power. The maximum horsepower of the low-power version is about 200 horsepower, the peak torque reaches 330Nm, and the acceleration of 0- 100km is 6.6 seconds. The 2.0T high-power version has a maximum horsepower of 280 horsepower, an amazing peak torque of 4 15 nm, and an acceleration of 0- 100 km in only 5.3 seconds.

Judging from Giulia's performance, to be honest, competitors are not as fast as him at present, but what hinders everyone from buying is the popularity of its brand in China and whether it is entangled in the back row space. ?
