Speaking of alpina, i'm sure the bimmers are no stranger. As an independent high-performance car manufacturer based on the bmw model, the “tangularity” with the bmw is the foundation upon which alpina can live, but its higher quality and performance than that of the bmw, that is, its mastery。
But bmw's own high-performance car m4, and the domestic start-up price is 927,000, and an alpina b4 based on 435i "refitting" can sell 1. 1 million? Although alpina b4's 100 km accelerator data is only 4. 0s, which is faster than the 4. 1s of the m4 dct model. It's more expensive than m4? We'll analyze it together。
Alpina, which was authorized by the bmw plant to retrofit the whole car for sale, would follow up almost as soon as the bmw introduced a new model. This time, alpina b4 bi-turbo, which introduced domestic sales, was reinforced on the basis of bmw 435i。
On the outside, the portion of the former bumper was replaced with the lower lip produced by alpina, while the side of the car was fitted with a line decoration exclusive to alpina, the back of the car was fitted with the classic duck tailings and a bi-bilateral exhaust pipe for a prominent sorbonne worker, akrapovič (commonly known as scorpion in the country), as well as a 19-inch turbo for the exclusive alpina。
The alpina modified technology was also significant, with the conversion of the n55b30 to the 6twinpower single turbo engine on 435i to double turbopower, with maximum power from the original plant's power of 306hp/400nm to 410hp/600nm and embroidered on the hood of the engine。
The "new" n55b30 engine re-engineered the catheters between the turbines and the gas cylinders and replaced the more responsive and less inert turbine pressors, as well as the larger aluminium alloy chillers. With respect to the gearbox, b4 uses an 8hp70 automatic gearbox from zf with maximum capacity to withstand 700nm's large twists, without losing double speed。
An improved bmw xdrive four-wheel drive system can be reserved for b4 by drivers who want a higher grip. The xdrive four-wheeled transmission system on board is more capable of generating a maximum of 50 nm more than m4. The four-wheel drive system, in addition to the automatic distribution of back and forth drivers, also has the function of right and right-twirl distribution and is equipped with a twister-rexler-created twister-resilient-resilient-resilient-resilient。
Msport, based on the selection of the original plant, adapted itself to the suspension system and was trained by alpina. According to the external pilot, the alpina-modifiable system has improved somewhat over the 435i and is more exciting in terms of driving。
Alpina b4 bi-turbo appears to have been retrofitted and upgraded in all directions, but does this mean that it can match m4
I don't think so
First of all, in mechanical terms, alpina b4 bi-turbo has squeezed n55b30 to the height of 410hp, but this is close to the limit that n55 engines can bear, after all, is a civilian-grade engine, which is essentially different from s55b30 on m4。
S55b30 has a direct 6-barrel 3. 0l double-turbation engine with a maximum power output of 430hp/5000-7300rpm, a peak twist of 550nm/1850rpm-5500rpm and a red-line rotation of up to 7500rpm. Although the maximum twister is less than 600 nm of b4, it is already 20 hp higher, and the machine has enormous potential, with a computer brushing, breaking 500 hp maximum and 650 nm peak。
Almost all parts of the engine are designed for weight reduction and greater intensity of materials are used to ensure the adaptability of the track, such as closed waterways for better heat dispersion. And for example, the surface of the cylinder is coated with lds, which makes it lighter and more resistant to pressure。
Pistols, poles and curves are of a lighter quantitative and more intense type. It also reduced the weight of the shell by 1 kg and increased the use of the track. With a massive and intensified effort, greater power can be derived from more extreme teaching and more efficient engines. It is almost impossible to “modify” n55b30 to s55b30, but only closer。
In order to reduce weight, m4 uses carbon fibre transfer axes, roofs, beams, tailcase caps (the c-smc process, known as carbon fibre reinforced membranes). The second five poles of manufactured aluminium alloy materials were also used to hang, and the plant was equipped with forged wheels. The chassis is very highly sensitive and sensitive, thanks to a lighter quantification of the exercise process and the by-carriage of all aluminium materials, together with m self-adapted to the suspension control system, and has received unanimous feedback from the national and international media, which have tried to say that m4 and b4 are more direct in their chassis performance and better suited to race。
More importantly, the latest m4 version of the mdrive system has become more modern, and almost every link to driver performance can be tailored to driver needs. For example, the response speed of the gas-gates, the suspension of hard and soft, the turning force, the speed of gearbox switching and the level of intervention in the stabilization system, each option has three models: efficient, report, and report plus. This must be the 435i model。
In this context, the gap between alpina b4 bi-turbo and bmw m4 is still quite large, and m4's quest for speed is even more extreme。
But b4 can give you comfort and luxury beyond your passion, and it's more acceptable to hang up, speedbox on the streets。
The pre-sale price of $1. 1 million is similar to that of the m4 dct model, which is very different abroad, so it is normal to set the pre-sale price domestically。
At similar prices, who would you choose
