Опубликовано: 31 янв. 2016 г.Фольксваген Пассат В8 образца 2016 года попал на тест-драйв уже после подробного знакомства с новым Шкода Суперб 2016. Тем интереснее сравнивать ездовые повадки, комфорт, техническое оснащение и цены двух конкурирующих автомобилей-одноклассников производства одного концерна VW.
Опубликовано: 27 авг. 2017 г.Since its launch in 2005, the Bugatti Veyron has been regarded as a supercar of superlative quality. It was a real challenge for developers to fulfil the specifications that the new supercar was supposed to meet: over 1,000 hp, a top speed of over 400 km/h and the ability to accelerate from 0 to 100 in under three seconds. Even experts thought it was impossible to achieve these performance specs on the road. But that was not all.
Bugatti set the benchmark even higher with the plan of turning the supercar into a luxury road car suitable for everyday use. The development of the Veyron was one of the greatest technological challenges ever known in the automotive industry.
Barely any parts, components or systems could be taken from existing car concepts and used in the Veyron. Everything had to be developed from scratch in order to achieve the performance specs and then everything had to be implemented in the car. The process also drew on the experiences of other industries in which materials and systems are routinely subject to extreme speeds and forces, such as aviation and space travel. The Veyron is the first – and the only – supercar to be developed and constructed with a series configuration that can master any driving scenario at any time. Even ten years after its launch, the supercar is still setting benchmarks and inspiring emotion and enthusiasm across the globe. Source: bugatti.com/veyron/
Technical maxims
The Veyron’s specs took automotive performance into a new dimension. It is the first – and the only – supercar to be developed and constructed with a series configuration that can master any driving scenario at any time.
While other supercars need to be specially prepared for the relevant scenario beforehand, the Veyron rapidly configures itself accordingly without the driver needing to do anything. Maximum acceleration on long straights, winding country roads or urban traffic – the Veyron is always perfectly configured and extremely comfortable to drive.
Engine
The heart and soul of the Veyron is the eight-litre W16 engine with four turbochargers, which initially generated 1,001 hp, and an incredible 1,200 hp in later models. The 16-cylinder mid-engine is 710 mm in length, no longer than a conventional V12 engine, and weighs just 490 kg due to its lightweight construction. The engine is fully capable of operating under a continuous full load, a feat that engines designed for use in motor racing, for example, cannot achieve. Its compact dimensions are due to the unique arrangement of its cylinder banks in a W configuration. Two VR8 blocks, each with a 15-degree bank angle, are joined in the crankcase to form one engine. Both eight-cylinder blocks are set at an angle of 90 degrees to each other and are aspirated by a total of four exhaust gas turbochargers.
Gearbox
The Veyron is equipped with a dual-clutch gearbox (DSG), which is the fastest gearbox in the world. Bugatti was the first manufacturer to use a seven-speed variant of the DSG. Designed specially for the new sports car, this gearbox has a job which any other road car gearbox would baulk at: to transfer engine torque of up to 1,500 Nm to the road surface.
At the time, the direct-shift gearbox used in the Veyron was a uniquely perfect combination of the dynamic advantages of a manual gearbox with the convenience of an automatic transmission. When it was developed, no other manufacturer had comparable technology.
Adaptive boost-pressure fuel injection
In a high-performance vehicle such as the Veyron, it is essential that the engine is always supplied with constant fuel pressure. This also required a new development, and so Bugatti invented AC injection pumps which, unlike conventional plus/minus polarised pumps, are able to supply the engine with the required amounts of fuel continuously at a constant pressure.
The fuel tank also had to be redesigned. Bugatti turned to the world of motorsport, but had to rebuild the conventional fuel tank used in racing, which is not permitted for road vehicles, to ensure that it would be approved. Bugatti consulted engineers in the aerospace industry, and the outcome was a fuel tank with an external Teflon coating which provides the fuel pumps with a constant supply of fuel in every situation, up to a residual capacity of three litres and maximum lateral acceleration of 1.4 G.

Тест-драйв KIA Optima (2016). «Убийца» Toyota Camry?
Опубликовано: 26 мар. 2016 г.Новый КИА Оптима 2016 во время тест-драйва бился за звание «Убийца Тойоты Камри». А заодно и Мазды 6, Шкоды Суперба и Форда Мондео до кучи. Если бы не прошлые слабенькие результаты продаж, в серьезность угрозы можно было бы даже поверить. Особенно, когда держишь в руках цены на новый KIA Optima и сравниваешь их с конкурентами.
Опубликовано: 16 февр. 2019 г.Увеличиваем дорожный просвет (он же клиренс) на Соренто Прайм (он же Kia Sorento Prime). Ходят слухи, что владельцы Праймов не довольны ”заводскими” установками. На сколько же увеличится клиренс у машины? Стоит напомнить, что через некоторое время новые пружины просядут и просвет чуть уменьшится. Так же проведем разбор подвески, что передней, что задней с последующей смазкой всего крепежа (болтов).
Новой машине — новые пружины! Даешь тюнинг Прайма! Главное, чтоб не было обратного эффекта.
