Based on its dimensions, the Audi A6 Avant e-tron concept clearly represents the upscale segments – 4.96 meters (16.3 feet) in length, 1.96 meters (6.4 feet) in width, and 1.44 meters (4.7 feet) in height, the same as the current models in the Audi A6/A7 series. With its dynamic proportions and elegant lines, including the Avant back end typical of the brand, it’s obvious at first glance that this vehicle was conceived in a wind tunnel. Aerodynamics has always played a key role in Audi’s long history of success in the luxury class. The cW value of the Audi 100 / C3 – the aerodynamics world champion of all classes in its day – is legendary: with its cW value of 0.30, Audi was already far outperforming its competitors as early as 1982, and continued to do so for many years thereafter. Now the electrically powered family of the Audi A6 e-tron concept is writing a new chapter in this success story, proving once again that the brand always combines form and function in perfect symbiosis. The Sportback’s cW value of just 0.22 is unprecedented in the electrified C-segment. With its expansive roofline, the Avant’s cW value is just 0.02 units above that. In layman’s terms, this means the car exhibits minimal aerodynamic drag – which initially translates into lower energy consumption and therefore extended range. At the same time, the fine-tuning in the wind tunnel has once again resulted in an organic design with exceptional elegance and harmony down to the last detail. Large 22-inch wheels and short overhangs, the flat cabin, and a dynamic roof arch give the Avant proportions that are distinctly reminiscent of a sports car.
The new Abarth 595 Range - Technology
Competizione and Esseesse are also equipped with the Garrett GT1446 turbocharger as standard. A mechanical, self-locking differential improves traction even in difficult grip conditions, such as uneven road conditions. Koni FSD shock absorbers on both axles and Brembo brakes with fixed aluminum brake calipers are also part of motorsport technology for the road. All variants of the 1.4 T-Jet engine are coupled with a mechanical transmission. The semi-automatic five-speed manual transmission "Abarth Competizione" is also available as an option from the Turismo version. It also enables gear changes using paddle shifters on the steering wheel and thus shortens shift times even further
With technology derived directly from Formula 1, the latest generation of the Mercedes‑AMG C 43 4MATIC sets new standards for innovative drive solutions both as a Saloon and as an Estate. Following its premiere in the Mercedes-AMG SL 43, the AMG 2.0-litre four-cylinder engine, the world's first series-production unit to feature an electric exhaust gas turbocharger, is now also being used in the C-Class. The new form of turbocharging guarantees particularly spontaneous response across the entire rev range and thus offers an even more dynamic driving experience. The turbocharger is operated via the 48‑volt electrical system, which also feeds the belt-driven starter-generator (RSG). In the Mercedes‑AMG C 43 4MATIC the unit produces 300 kW (408 hp) and, in certain driving situations, is able to call upon a brief additional boost of 10 kW (14 hp) from the RSG. The standard rear-axle steering, the AMG Performance 4MATIC permanent all-wheel drive with rear-biased torque distribution, the AMG SPEEDSHIFT MCT 9G transmission with wet start-off clutch and the AMG RIDE CONTROL suspension with Adaptive Damping System also contribute to the dynamic driving experience. In keeping with this, brand-specific features in the equipment and appointments as well as in the exterior and interior design emphasise the performance-oriented character of the new Mercedes-AMG C 43 4MATIC.
The BMW Group is beginning to test near-standard vehicles with a hydrogen fuel cell drive train in everyday conditions on European roads. Prototypes of the BMW i Hydrogen NEXT will examine how effectively the CO2-free drive train, model-specific chassis technology and vehicle electronics systems work together under real-life conditions. The BMW i Hydrogen NEXT is a pure electric vehicle that uses hydrogen as fuel by converting it into electricity in a fuel cell. The recently launched testing programme will pave the way for the BMW Group to present a small-series model with this sustainable drive technology, developed on the basis of the BMW X5, in late 2022. Extensive field testing of these vehicles will provide practical experience in the use of this sustainable drive technology. Hydrogen fuel cell technology has the long-term potential to supplement internal combustion engines, plug-in hybrid systems and battery-electric vehicles within the BMW Group’s flexible drive train strategy. It could become an attractive alternative to battery-electric drive trains – especially for customers who do not have their own access to electric charging infrastructure or who frequently drive long distances.
