2021 Ram 1500 TRX Engineering Feature
Jeff Roselli, TRX model responsible, talks about the engineering for the all-new 2021 Ram 1500 TRX.
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.

With its robust appearance and functional versatility, the new BMW X1 embodies an authentic experience of freedom and independence in day-to-day driving and on longer journeys. The interior’s progressive design and sophisticated ambience, and the much broader selection of standard equipment compared to the outgoing model, serve to underline its deeply embedded premium character. At launch in October 2022, there will initially be a choice of two petrol and two diesel engines. These will link up with a seven-speed Steptronic transmission with double clutch as standard, and their drive power will be channelled to the road via either the front wheels or the BMW xDrive intelligent all-wheel-drive system, depending on the model. This starting quartet will immediately be followed by the all-electric BMW iX1 xDrive30 as well as by a pair of plug-in hybrid models and another two conventionally powered variants with 48V mild hybrid technology. The new BMW X1 will be built at BMW Group Plant Regensburg, where models with combustion engines, plug-in hybrid systems and all-electric drive will all roll off a single assembly line for the first time. The BMW iX1 will bring the experience of locally emission-free driving pleasure to a vehicle segment enjoying worldwide growth, making it accessible to a very wide target audience. The compact SAV powered by the latest BMW eDrive technology will therefore give a major boost to the accelerated ramp-up of electric mobility. The improvements in sustainability compared to the predecessor model can be partly attributed not just to the wide-ranging electrification measures, but also the increased use of green energy, both for production and in the supply chain, and the greater quantities of secondary raw materials and natural materials used.
The Audi A6 Avant e-tron concept combines dynamic elegance with an all-electric drivetrain. A design highlight is the digital OLED technology included in front and rear lighting. The exterior design is optimized for ideal aerodynamics, a closed singleframe grille is integrated in the front.
