Artega names first electric sports car after race champion stallion ‘Scalo’

Article by Christian Andrei, on September 17, 2015

Many people have long wanted a complete electric drive offering from Artega. In fact, the thought of coming up with an electric sports car seems to be as old as the brand itself. The wait is finally over with the Artega Scalo. While being the first for the brand, this electric car not just succeeds the Artega GT but also brings new technical innovations and elegant appearance. Take the chassis for example. Its modular structure and light-weight materials make this platform the best when it comes to electric drives.

Before the Artega Scalo, there have been three prototypes made as of 2012 but none made it to production mainly due to design issues. The brand believes that this new electric car will form the basis of a new practice. In particular, Artega expects that future vehicle models of the brand will be named after famous racing stallions. The first of course is Scalo, a Westphalian stallion, who was the 2010 Galloper of the Year. In addition, Scalo was trained near the company’s head office.

According to the manufacturer, the battery has a capacity of more than 37 kWh with nominal voltage measured to be at 411 Volt. However for about 10 seconds, an electric output of 385 kW is possible. Maximum range of the Artega Scalo is 250 miles.

One exceptional feature of the battery is that when the charge status drops below the 25% level, speed is limited to 125 mph. This is not just about safety as it also allows the car to travel farther. Overheating is not that much of a problem since the battery has a cooling circuit of its own.

In addition, the power electronics as well as the electric motors share a second cooler. Thus all the components are able to work at their best. A 64-kW DC quick charge makes it possible for the battery to have a complete charge in less than an hour. The Artega Scalo has its own on-board charger and is able to attain maximum charge output, using a 22-kW three-phase current connection.

This can result to an estimated two-hour charging duration. When an AC grid through a 16-A household socket is used, the charging duration is about ten hours. With regards to storage volume, the Artega Scalo’s measures 8.8 cubic feet which is distributed between the trunk at the front and the space located at the back of the seats.

Including the batteries, the empty weight of the Scalo is 3,494 lbs. The forged central closure rims measure 8.5“x 20” at the front with tires at 245/35 x 20 and 11“x 20” at the rear having 295/30 x 20 tires.

The mass of the rim on the front is 21.3 lbs. while the rear one weighs 24.4 lbs. Finally, there are the Brembo brake calipers. It has 6 pistons on its front, 4 pistons at the rear plus a separate caliper for its hand brake. This calipers when mixed with its two-part brakes show just how much experience the brand has when it comes to racing.


Inside the Scalo are two high-performance rear-mounted Voltabox electric motors. Each motor has a power output of 300 kW with maximum output of 390 kW. Maximum torque of each motor measures 575 ft-lb. The electric motors make the Scalo better than its predecessor, allowing acceleration of 0 to 60 mph in just 3.6 seconds while being able to reach top speed of 155 mph. What makes the electric motors more efficient is that they utilize the newest aerospace technologies.

This is the same technology that drives the Scalo’s rear axle through a single-stage central gear. A targeted torque vectoring system enables optimal longitudinal and cross-dynamics which works with its demand-oriented distribution through the drive wheels. Since the electric motors only weigh 66 lbs. each, performance density is managed at 2.3 kW/lb. though the motor speed has a maximum of 12,500 rpm, the electric motors can get 95% efficiency even at 6,900 rpm.

Customization is available by request and Artega offers a version that has 98% efficiency. Furthermore, the Voltabox electric motors are controlled by two inverters which also supply it with power. The inverters have 93% efficiency. Special silicon carbide transistors are available for some variants and it is able to attain a maximum of 98.8% electrical energy conversion. When not used, the energy being produced can also be stored.

The Artega Scalo for the first time is offering a hybrid system that has innovative battery modules and thermally controlled lithium-ion cells with a nickel-manganese-cobalt basis which will then combine with the high-performance capacitors or SuperCaps. In order to recover more quickly, the SuperCaps recharge fairly fast but when the car accelerates, the capacitors will be the first ones to discharge. This pattern not just increases the acceleration but can also extend the range of the Scalo.

This system of recovery can be increased and adjusted by the driver four-fold simply by switching the paddles located at the steering wheel. The lithium-ion cells are integrated to the Scalo’s structure in order to protect it from crashes.

It has also been distributed through two systems and with the capacitor positioned in the car’s center of gravity, the weight is distributed well. Both Voltabox thermal and battery management have been integrated and are considered safe in relation to DIN/ISO 26262 standards.

Press Release


The time is ready for an Artega sports car with a purely electric drive. The new German electric sports car Artega Scalo entices as a direct successor of the Artega GT by visual refinement and many technical world novelties. It is built in a small series of twelve exclusive vehicles to order.

The idea of developing an Artega as an electric sports car is as old as the brand's history. Consistent light-weight construction and the modular construction of the chassis make the Artega platform perfect for electric drives. Three prototypes have been built by 2012, but not made it for serial production due to their design. The purely electric Artega Scalo founds a new tradition.

In future, the vehicles of the Artega brand will bear the names of famous racing stallions. Scalo is the first – he was a very special Westphalian stallion, Galloper of the Year in 2010 and trained very near the head office of Artega.

The Artega Scalo has two Voltabox rear-mount high-performance electric motors with a total output of 300 kW (peak output 390 kW) and a 575 ft-lb. It thus outdoes the performance data of its predecessor. The Artega Scalo accelerates from 0 to 60 mph in 3.6 seconds and reaches an electronically limited maximum speed of 155 mph.

The two electric motors use the latest technologies right from aerospace and drive the rear axle via a single-stage central gear. Targeted torque vectoring ensures maximum longitudinal and cross-dynamics with the demand-oriented distribution across the drive wheels.

The motor mass is only 66 lbs each, which leads to an outstanding performance density of 2.3 kW/lb. The maximum motor speed is at 12,500 rpm, the maximum efficiency at 6,900 rpm is up to 95%. On request, a version with an outstanding efficiency of 98% is available.

The Voltabox high-efficiency machines are supplied and controlled via two newly developed inverters with an efficiency of up to 93%. A version with special silicon carbide transistors even achieves a maximum electrical energy conversion of 98.8%. The energy storage also offers a global novelty.

For the first time, the Artega Scalo offers a hybrid system of state-of-the-art battery modules with actively thermally controlled li-ion cells on nickel-manganese-cobalt basis, combined with perfectly customized high-performance capacitors (SuperCaps). For recuperation, the SuperCaps recharge quickly at first; at acceleration, the capacitors will discharge first.

This constellation increases acceleration and extends the range. The recuperations system can be adjusted four-fold by the driver by switching paddles at the steering wheel. Strong range of up to 250 mls The li-ion models are distributed between two systems that are crash-protectedly integrated into the vehicle structure.

The capacitors placed in the centre of gravity also ensure best weight distribution. The Voltabox thermal and battery management is fully integrated and functionally intrinsically safe according to DIN/ISO 26262. The installed battery capacity is in excess of 37 kWh, the nominal voltage is at 411 Volt.

For up to 10 seconds, as much as 385 kW electrical output can be demanded. The Artega Scalo has a range of up to 250 mls.At a charge status below 25%,the power output is limited to 125 mph at most for the sake of a better remaining range, however. The battery set has its own cooling circuit. The power electronics and the two electric motors have a second shared cooler.

This way, all system components work at their respective best working points. With a 64 kW DC quick charge, it is possible to charge the battery completely in less than one hour. The maximum charge output of the Voltabox on-board charger at the three-phase current connection is 22 kW, which corresponds to a charging duration of approx. two hours.

At the AC grid with a 16 A household socket, it takes approx. ten hours. Large storage volume and beautifully shaped wheel rims The new German electric sports car has a storage volume of 8.8 cft that are distributed among the front trunk and the space behind the seats. The empty weight of this vehicle, including batteries is at 3,494 lbs.

The Artega Scalo has forged central closure rims in a dedicated design (8.5“ x 20” front, 11“ x 20” rear) and tyres sized 245/35 x 20 resp. 295/30 x 20. The rim mass in front is only 21.3 lbs and at the rear 24.4 lbs. The installed Brembo brake callipers (6 pistons front, 4 pistons rear with separate calliper for the hand brake) with two-part brake discs reflect the brand's experience in racing sports.
