Mercedes formally launched the sporty long-range Vision EQXX idea at a digital occasion again in January, promising 1,000 km (621 miles) of per-charge vary in regular driving situations. Now the corporate has put that declare to the check on a cross-border European street journey.
The idea car’s environment friendly electrical drivetrain has been developed in collaboration with F1 specialists from Mercedes AMG High Performance Powertrains, and has a peak energy output of 180 kW (241 hp) and is reportedly in a position to ship as much as 95 % of the principle battery’s vitality to the wheels.
That 100-kWh battery pack is reported to be on an virtually equal vitality footing to the corporate’s EQS manufacturing car, however is available in 30 % lighter at 495 kg (1,091 lb) and with dimensions of 200 x 126 x 11 cm (78 x 49 x 4 in) it takes up round half the house too.
At the beginning of the European street journey from Mercedes’ Sindelfingen R&D heart, close to Stuttgart in Germany, engineers sealed up the charging socket and invited an unbiased observer from the TÜV Süd certification physique to take the passenger seat.
The thought was to check the car in real-world situations, and high-speed driving featured early on within the journey because the Vision EQXX took to Autobahn 81 at as much as 140 km/h (87 mph) on the way in which to Switzerland – taking advantage of the idea’s low drag coefficient of 0.17, achieved because of the flowing physique form, compact entrance finish, specifically developed Bridgestone tires with low rolling resistance and lively rear diffuser that mechanically deploys at speeds above 60 km/h.
The idea quickly made its approach throughout the Swiss Alps, after which made essentially the most of an extended downhill drive towards Northern Italy by recuperating vitality and feeding it again to the principle battery financial institution. As the prototype headed south, the rainclouds cleared and the Sun started to shine down on the 177 photovoltaic panels linked to a separate 12-V battery that is used to energy auxiliary programs and take a number of the pressure off the principle battery financial institution, with Mercedes estimating that doing so can add an additional 25 km (15.5 miles) to the already spectacular vary determine.
The route took the workforce down previous Milan earlier than heading west towards the journey’s finish – the picturesque commune of Cassis close to Marseille within the Provence-Alpes-Côte d’Azur area of southern France. In all, the journey took simply over 12 hours, clocked up 1,008 km (626 miles), and did not contain a single charging cease alongside the way in which.
Temperatures throughout the journey ranged from 3 to 18 °C (37.4 – 64.4 °F), whereas climate situations moved from gentle rain to shiny sunshine. Mercedes experiences that there was nonetheless some 15 % cost remaining on the finish of the epic EV journey, which labored out at round 140 km (87 miles). Average pace was calculated to be 87.4 km/h (54 mph), high pace rolled as much as 140 km/h.
“We did it! Powering through more than 1,000 kilometers with ease on a single battery charge and a consumption of only 8.7 kWh/100 km in real-world traffic conditions,” stated the Chairman of the Board of Management at Mercedes-Benz, Ola Källenius. “The Vision EQXX is the most efficient Mercedes ever built. The technology program behind it marks a milestone in the development of electric vehicles. It underpins our strategic aim to ‘Lead in Electric’.”
Though the Vision EQXX stays an idea, Mercedes is planning to make use of know-how showcased within the analysis prototype for future series-production autos.
