M otorsport is not the development of new drive methods only useful, it also makes the state of the art visible to everyone. In this respect, the Silvretta E-Auto Rally, which was driven out for the seventh time this year, has given a lot of fascination and capacity: the first edition of the mountain test for the electric drivers was limited to moderate distances of around 50 to 80 kilometers per day, The 135 kilometers on the second day are no longer a problem six years later. All 25 participants arrive carefree with enough electricity on the 1,486 meter high Faschinajoch, and downhill - towards the destination in Bregenz - the recuperation then recharges.

E-cars shape their world

As meticulously as the regularity tests wanted to be completed to the hundredth of a second, the discussions about the future of electric driving among the participants and spectators were so passionate: Everything just an interlude, or will the still missing infrastructure of the charging stations gradually make up?

Mercedes, next to BMW and Kia with no less a ls eight hybrid, battery and fuel cell models from the B-Class to the E-Class, GLC, AMG SLS and S-Class at the start, gave a brief overview of the status of the e-discussion on the evening of the first day Germany. According to Jürgen Schenk, who is the chief engineer for electrical engineering at the Stuttgart manufacturer, the federal government has decided to support the nationwide installation of 15,000 charging stations with a 50 percent grant with immediate effect.

The pillars, Equipped with 16 connections each, four fast-charging devices should be available. The aim of decreasing charging times: store enough electricity in one minute for a 100-kilometer drive in the car.

Fuel cell technology also seems to be a viable solution in use. The currently available Fuel Cell B-Class can, for example, be equipped with a medium-sized battery to provide electricity like a plug-in hybrid for the average distance of 40 kilometers per day, which is common in this country. On longer journeys, the small power plant in the car is used to generate electricity: the fuel cell.

E-cars are catching up

The consumption balance of the plug-in hybrids from Mercedes shone on both rally days : Of the 78 kilometers of the first loop in the Montafon, that of auto motor und sport initially driven GLC back no less than 46 without using the combustion engine. Even the trained driver hardly notices the automatic change between the two drive systems and remains more a case for the screen and its display of the force flows than a case for the so-called popometer, without whose sensitive feedback no automobile tester could do.

If the impression of comfort seems difficult to increase even in the GLC, this is all the more true in the plug-ins of the E- and S-Class. The soft electrical rolling can be perfectly dosed in a duel with the light barrier or the pressure hose to be rolled over for timing; the usual excuses that the two seconds deviation from the target time could be attributed to the clutching clutch are no longer caught in the electric age.

The B-Class with fuel cell technology used on the second day consumed a total of around 250 kilometers, barely half a tank full of hydrogen, which means a range of 500 kilometers per filling, even in the mountains. Without question, electric driving has made up a lot of ground on the combustion engine over the past six years. And that is almost the most important finding as a result of the e-car rally.

Rally with a colorful starting field

Victory was fiercely contested despite the general agreement on the future of e-drive . In addition to two i3s with an additional range extender engine, BMW also used two electrically powered Active Tourer hybrids, which are called 225 xDrive iPerformance, and a 740Le xDrive. Kia sent two Soul EVs into the race, Illwerke bet on two Renault Zoe, two BMW i3 and a VW Golf.

Two Tesla hummed under Klaus Ege and Christian Altenberger at the start, and then came the two absolute ones Exotic: Hans-Werner Ulepic and Mrs. Hildegard drove a VW T2 bus from the 1970s, which was once manufactured as a low-emission company transporter. The due restoration was linked to the social project “Dorstener Arbeit”, and since then Ulepic has been driving the electric van for the advertising aid project wherever he can. The transporter, which is equipped with Siemens technology and has a battery weight of three quarters of a ton, is accelerated to up to 70 km /h by a 33 kW motor.

The electric Volkswagen transporter attracts attention because of its early year of construction and its With its nostalgic body, the rally car of the Swiss Martin Müller-Hafner scores with the hottest sports car body its owner can imagine: 'I fell in love with the Fisker Karma at the Geneva Motor Show 2010, and then I had to have one.'

As in the Lohner-Porsche from 1901, a gasoline engine drives the dynamo as a range extender, which then transfers the electrical power to the two 150 kW electric motors. It drives purely electricallyfour-seater Karma up to 81 kilometers and a good 130 km /h; With the extender switched on, the design by Danish designer Henrik Fisker achieves around 200 km /h.

A combustion engine as a range extender can be operated with less pollutant emissions than a direct drive motor. The reason: It runs at a constant speed and is therefore optimally lean. There is no need for an additional fuel dose, for example when accelerating or at full load. This also applies to this year's winner of the Silvretta E-Auto Rallye, a works BMW i3.
