D ye eyebrows? Torn away. The face? Looks like ground beef. The hair? Standing in all directions, like after an electric shock. How many flies? Felt thirty slapped on the forehead, one swallowed. Helmet? You had to drive topless once, only then do acceleration and lateral forces really go straight into your blood.

Shorthand of the first test meter in the radical SR3 SL on public roads in Germany. Anyone who thinks we suffer is wrong. Today it is exactly 34 degrees warmer than the first rendez-vous with the British mini-series vehicle in the guise of an LMP prototype on a scale of 1: 2. The first exit with the Radical SR3 SL in Peterborough, UK, was more like ice skating with semi-slicks in sleet.

Pedestrian zone Hockenheim: If the hurricane has a break in the open cockpit, curious people ask the driver like at a press conference. “In downtown Cologne, some people run into the street at the traffic lights and ask what kind of car that is,” says Patrick Mothes. With his motorsport team Mothes GP he offers race taxi rides and driver courses in the Radical. In addition, the Cologne-based company is the first owner of a Radical SR3 SL, which is street legal in Germany.

British exotic with Ford power

For all those who do not know the British exotic brand, here is a brief overview: Founded in 1997, 150 employees, record year 2011 with 220 vehicles sold, made famous by ultra-light racing prototypes with Hayabusa motorcycle engines. Even if the 765 kilo Radical SR3 SL looks similar to the racing version SR3 RS, a different concept is hidden behind the fiberglass body. In the rear, a four-cylinder motorcycle no longer screams, but a 243 hp Ford Ecoboost four-cylinder with Euro 5 emissions standard hums and buzzes. A sequential six-speed gearbox and a differential lock from Quaife take care of the power transmission.

Enough time lost in town, saddle up and jump into the knee-high cockpit. Flip the main switch, turn the ignition key, press the start button - back into the world of free radicals. Airbag, ESP? The question arises. In England they wouldn't speak to you for a day. Starting off is compatible with the city without jerking, then the clutch has untilnext start-up process after work. Clack, clack, clack - the steering wheel paddles switch sequentially without a clutch. Gear changes in 80 milliseconds with a Formula 3 soundscape. Behind the right ear, the four-cylinder snorkeled greedily through a Formula 1-like air scoop, as if it wanted to suck your head away. Place name sign Hockenheim, tied with six-point seatbelts you go on the country road.

Radical SR3 SL to 100 km /h in 3.5 seconds

The Radical SR3 SL lightweight whips from zero to 100 km /h in 3.5 seconds. The 620 hp Porsche 911 GT2 RS sprints over the 100 mark just as quickly - the Radical, however, unfiltered without launch control. The brakes are just as brutal: the tubular frame racer is in the test from 100 km /h after 33.8 meters. A Porsche 911 GT3 RS 4.0 with ceramic brake is only 20 cm earlier on zero. The Radical throws the anchor without braking assistance and ABS.

Looking without a windshield over two exposed wheelhouses, rushing along at bumper height of the normal road users, the brain switches between all the endorphins with the following question again: “And everything is officially approved for road use in Germany?” “Yes, Radical delivered the car with COC. But their eyes fell out at the registration office in Cologne when they saw the Radical SR3 SL, ”says Mothes GP boss Patrick. The car was not listed at the Federal Motor Transport Authority. “The car was unknown. We then had to present the vehicle to the TÜV to the registration office. Then we were able to let him in, ”remembers Mothes, who has so far passed a police check twice with the Radical SR3 SL without any problems.

Approval possible in Germany

The times when exotic manufacturers with the strangest vehicles could simply insist on EU-wide approval after approval in England are long gone in Germany. After Radical had tried unsuccessfully years ago to get a road license for Germany, the tide has turned with the SR3 SL. “The car is completely clean. Radical has an EC type approval. This means that it can be approved in Germany without any problems. The vehicle is in a similar registration class as the KTM X-Bow. Compared to mass-produced cars, the requirements in the area of ​​pedestrian and occupant protection as well as the subject of wheel covers are more relaxed, ”explains approval expert Frank Fricke from Dekra.

The Mothes GP team had to do pioneering work not only on the subject of road approval . Technically, the Radical SR3 SL sometimes looked like a surprise egg when it was delivered. The rear wing broke once. Mothes GP then recommended that the parent company retrofit two central bars. In addition, the radiator and transmission had to be sealed. “We have the technology somethingMade more German, ”says Patrick Mothes with a smile. In order to improve the delivery quality of the cars, a new German importer, Karl-Heinz Teichmann, who is experienced in racing, is now checking the vehicles in this country before delivery. In addition to the standard steering wheel, which is a bit too large, Mothes GP also has a sports steering wheel developed with Momo for the racetrack in its range.

Podium for Hockenheim Lap time

From the pedestrian zone to the test on the small Hockenheim circuit. The Radical SR3 SL raises agility to new dimensions: steering via thought transmission. Braking like in a formula vehicle - without ABS, but with deceleration values ​​of 13.80 m /s². It hardly gets any sharper. the transverse dynamics formula complements the constant downforce here. Thanks to the downforce, the Radical SR3 SL runs at 192 km /h through the left-hand bend of the crossbar. For comparison: Gumpert Apollo 185 km /h, Porsche 911 GT2 RS 180 km /h, Lamborghini Aventador 172 km /h. The Radical SR3 SL climbed to the podium in Hockenheim with 1.08.1 minutes in the sport auto test as the third fastest vehicle of all test lap times. With only 243 hp, it is as unbelievable as if a Trabi had won a drag race. However, the Concept M EXP /1 based on Mosler has now made it to the top of the list of the best with a record lap time.
