Mercedes-Benz debuted the EQ Silver Arrow show car at Monterey Car Week The one-seater EQ Silver Arrow is – allegedly- an homage to the successful record-breaking W 125 car from 1937. The Alubeam (sic) Silver paintwork, which will never see a race track – is vaguely like the historic Silver Arrows which, for weight reasons, did not have a white paint layer. Well, the rear diffuser hints of motorsports with two extendible rear spoilers that act as an air brake by increasing the wind resistance when deceleration is desired.

The nascent EQ sub-brand of electric vehicles (not to be confused with atomic weights) is “shaped by the avant-garde, distinct aesthetic of Progressive Luxury, which arises from the combination of a previously unknown beauty, the conscious clash of digital and analogue elements, as well as the seamless merging of intuitive and physical design.
“More than 80 years ago, the historic Silver Arrows demonstrated that Mercedes-Benz was a pioneer when it came to speed, thanks, among other things, to their streamlined shape,” says Gorden Wagener, Chief Design Officer at Daimler AG. “The EQ Silver Arrow show car draws on that legacy. Intended for acceleration and driving pleasure, it embodies progressive luxury and provides an insight into the future of our design. As a result, the show car drives the design idiom of our new EQ product and technology brand to the top.”
The EQ brand is “shaped by the avant-garde, distinct aesthetic of Progressive Luxury. Highlights include the driver’s cockpit, which can be folded forwards, and the partially free-standing multi-spoke wheels.” The non-rotating hub caps (spinners?) and the partial trim on the wheels are other highlights. The 168 spokes per wheel are made of lightweight aluminum and painted a rose/gold color, which is also a sign of the EQ brand.
Offering good traction – in theory – and correspondingly fast acceleration, the EQ Silver Arrow has slick 255/25 R 24 tires at the front and 305/25 R 26 tires at the rear. Attesting the attention to detail, tire partner Pirelli embossed a star pattern on the tread.
The rear diffuser is reminiscent of motorsports with two extendible rear spoilers that act as an air brake by increasing the wind resistance when deceleration is desired.
The interior of the EQ Silver Arrow represents the values of Progressive Luxury with a design idiom that combines timeless aesthetic appeal (yes, they said that) with a futuristic vision. To match the exterior paint finish in Alubeam Silver, the side walls of the interior are covered in a luxurious, grey suede.
Double Screen and Virtual Racing
The driver of the EQ Silver Arrow is surrounded (captured?) by a large panoramic screen on which a 3D image of the surroundings is projected from behind. As an indicator of future possible charging technologies, the lane of the roadway on which inductive charging is possible is superimposed onto the screen.
Via artificial intelligence, it is possible to engage in a virtual race against historic or present Silver Arrow racing cars. A virtual racetrack is superimposed onto the real roadway via the panoramic screen and the driver sees their opponent either ahead of them or behind them as a “ghost.” The Virtual Race Coach assistance function allegedly helps one improve driving skills by giving instructions during the race.
The driver can use the touchscreen on the steering wheel to select programs such as Comfort, Sport and Sport+, which offer different driving characteristics. Sound settings can also be configured here: choices include the sound of a current Formula 1 Silver Arrow or a Mercedes-AMG V8 engine, neither of which sound like they are electrically powered.
Ah there’s nothing like the roaring sound of kilowatt engines. The EQ Silver Arrow is conceived as an electric vehicle with an output of 738 hp. The thin rechargeable battery in the underbody has a usable capacity of approximately 80 kWh and enables an approximate range of over 250 mph. Side air vents help to cool the battery.
EQ Concept Vehicles
At the 2017 Frankfurt Motor Show, Mercedes-Benz tried to explain how the EQ strategy can be translated to the compact class with the introduction of the Concept EQA – thus far missing in, well, inaction. With one electric motor on the front axle and one at the rear, this electric car has a system output of over 268 hp. The drive characteristics can be changed by varying the full-time all-wheel drive’s front to rear torque distribution. The Concept EQA then displays which drive program has been selected on a unique virtual radiator grille.
You may recall that smart also presented the smart vision EQ fortwo at the 2017 Frankfurt Motor Show – an electric and autonomous vision for highly efficient and flexible local public transport. Autonomous and electric-powered, the smart vision EQ presents a consistent concept for the future of urban mobility and the future of car sharing. The vehicle picks up its passengers directly from their chosen location and has no steering wheel or pedals.
The Concept EQ, unveiled at the 2016 Paris Motor Show, debuted the new EQ product and technology brand – a concept vehicle with the aesthetic of a sporty SUV coupe that pre-empted many elements of the Mercedes-Benz EQC.
The Real Silver Arrow
Using a thread bare marketing technique, borrowed interest, the role model for the EQ Silver Arrow is the W 125 twelve-cylinder, record-breaking car built by Mercedes-Benz in 1937 as a Grand Prix racing car.
For the W 125’s new body in 1937, Mercedes-Benz was stealing from the aviation industry. Examples include the recommendation from the development departments of the aircraft factories of Ernst Heinkel and Willy Messerschmitt to shorten the front overhang and to make the front rounder. The front was also extended further down, and the tip veered off at a steeper angle. As desired, this reduced lift on the front axle. A longer and more stoutly raised rear reduced lift on the rear axle. One inspiration for the designers of the EQ Silver Arrow was the round cockpit glazing, which was modeled on a drop of water for its outline and cross-section.
Rudolf Caracciola achieved 432.7 km/h (268.9 mph) on the A5 autobahn with the W 125 between Frankfurt and Darmstadt based on the average speed traveling there and back. This speed remained the record on public roads until November 2017.
