What we know about Electric Raceabout?

Well, we do know that it is an all-electric sports car developed by the  Helsinki Metropoloa University of Applied Sciences and a lot of people have worked under this project (the majority of the 60 companies and institutions involved with the project are from that Nordic country).

Wow,it sounds like a lot of work have been done and fairly, it is.


ERA was introduced in summer 2009 with a target to reach a low volume production.

ERA took part in Automotive X Prize competition and came in second in its class. ERA made a new road-legal electric vehicle lap record  in September 2011.

In winter 2011–2012, ERA had its inverters, aerodynamics and power steering upgraded – after improvements ERA's total motor power of 282 kW was measured on dynamometer. In March 2012, ERA topped a speed of 260 km/h while driven on ice at Lake Ukonjärvi, Inari. With average speed of 252 km/h, ERA is the fastest EV on ice. ERA was parked outside in freezing temperatures before the event, proving that an EV can operate in freezing temperatures.



One of the technologies involved are the direct-drive motors the ERA has powering each wheel (it means that there're four seperate wheel motors with innovative configuration), custom inverters, and a special supervisory controller all designed and constructed by a team of university students from the Metropolitan University of Helsinki, Finland.



Powerful battery      

Using almost 33 kWh of Altairnano  lithium titanate batteries optimized for power rather than energy, this densely packaged car weighed 3770 pounds yet demonstrated impressive efficiency. 







Audi R8 similarities

The students used Audi R8 supercar aluminum suspension and brakes to match the driving performance of this vehicle. Given the mass, overall size, and battery makeup of this car, its results clearly show that traditional OEMs could build a similar car with existing technology that would achieve a similar attractive blend of energy efficiency and high performance.










Drive type: Battery electric, all-wheel-drive
Power source: lithium-titane batteries
Charging: Fast-charging is available, that will charge the car to 80 percent capacity in 10 minutes on a 250 kw supply.

Battery:lithium-titane batteries, four direct drive electric motors and a carbon-fiber monocoque chassis with steel sub-frames.

Range: 200 km.

Ttotal weight: 1,700 kg

Battery weight: 550 kg battery pack.

Power output of its engines: 200 kW with a peak output of 300 kW / 10 seconds.

Engines' nominal torque: 1000 Nm with a peak torque of 3200 Nm.

Top speed: 285 km/h with 0–100 km acceleration in 6.0 seconds (new record)















New speed record 

Metropolia Electric RaceAbout road legal electric vehicle top speed record 285.31 km/h at Lappeenranta airport during Unlimited Racing event on June 28th 2014. Driven by Janne Laitinen, the car recorded 0-100 km/h, 6,3s and 0 - 100 mph in 10,6 s.

The secret of a new record is pretty simple.

As we have seen from car's specifications, the latest modification of ERA has a 33 kWh Altairnano lithium-titanate battery which powers four-electric motors that develop a peak output of 383 PS (282 kW / 378 bhp) and 3,200 Nm (2,360 lb-ft) of torque. This enables the 1,700 kg (3,747 lb) prototype to accelerate from 0-100 km/h in approximately six seconds and travel approximately 200 km (124 miles) on a single charge. At top speed the ERA consumed around 1250 Wh/km measured as energy required from grid to recharge the battery.
