General Motors’ vision of an all-electric future is coming into clearer focus and gaining momentum with a $2.2 billion investment at its Detroit-Hamtramck assembly plant to produce a variety of all-electric trucks and SUVs. GM’s first all-electric truck will be a pickup with production scheduled to begin in late 2021.The first advertising spot lasting 30 seconds and regarding the new GMC Hummer EV appeared for the first time during last Super Bowl. Currently General Motors has diffused the front image of the new electric Hummer. The predominant element that catches the attention? When the vehicle starts, the front of the car lights up, highlighting a design of great visual impact. Concerning technical specifications, at present we know the vehicle features 1,000 HP power and maximum torque exceeding 15,500 Nm. Performances? In 3 seconds, the electric pickup accelerates from 0 to 60 hourly miles, corresponding to 96 Km/h; values that seem to belong to a super sports car.
The new entry version of the sports electric Porsche-branded car is called Taycan 4S and it is the third version of this model.
Already orderable and incoming in concessionaries since January 2020, this version is available with two batteries: performance that supplies a power up to 530 HP and the Performance Plus, whose power rises up to 571 HP. In both cases, the Porsche Taycan 4S accelerates from 0 to 100 km/h in 3.8 seconds and reaches a maximum speed of 250 km/h. The autonomy the vehicle can reach is equal to 407 kilometres with the Performance option and as many as 463 kilometres with the Performance Plus, the highest value of the current Taycan range.
Like Turbo models, Taycan 4S has the all-wheel drive due to two synchronous motors, one for each axis. There is also the two-speed transmission on the rear axle and the standard Porsche Active Suspension Management (PASM) with pneumatic suspensions.
After 2700 kilometres through the Rocky Mountains region, from Nebraska to Oregon, the Solar Wave team – the only European team in the race – ended the course winning the first place and two special prizes with the “Emilia 4” vehicle: the award for the best mechanics and use of composites and the award for the best battery project. It is a success of Bologna University in the Automotive sector on a global scale, paving the way for possible important reverberations in industrial field.
The vehicle, developed by Solar Wave team, looks like a conventional car but with a big difference in the consumption aspect: to move, Emilia 4 uses an amount of energy similar to what is needed to power a hairdryer. With two electric motors positioned behind the wheels, it is fuelled by five square metres of high-efficiency solar panels connected with state-of-the-art lithium batteries.
Emilia 4 crossed the finish line exclusively exploiting the solar energy, without ever being connected to the electric grid to recharge its batteries, and travelling autonomously the entire course, whereas all other racing vehicles needed to be towed on a cart for at least one section of the track.
Born from an industrial research project funded by Emilia-Romagna Region through European financing – Por Fesr 2014-2020, Emilia 4 was fully developed and built in Emilia-Romagna by Bologna University and by the Solar Wave team, with the involvement of Interdepartmental Centre for Industrial Research in Building and Construction, the Interdepartmental Centre for Industrial Aeronautical Research and the support of various companies and research centres, including Cineca Supercomputing Centre and Scm Group. The engineering activity, which involved around sixty people, lasted two years whereas the construction phase was accomplished in less than one year.
To meet the universal desire for a transition to decentralised energy generation from renewable sources, new and innovative solutions for stabilising the electricity grid are necessary. The increasing use of renewable energy leads to fluctuations in the grid, which must be initially balanced by primary regulation, able to prevent impending power cuts at a second’s notice.
In Hagen (Germany) an important milestone on the road to emission-free energy and mobility has been achieved by technology company The Mobility House, energy supplier Enervie, transmission system operator Amprion and car maker Nissan. With the Nissan Leaf and an innovative charging and energy management technology, the project partners have succeeded in qualifying an electric car for all the Tso regulatory requirements for primary power regulation. This means that the car can be integrated as a regulating reserve for the German electricity grid – a breakthrough in the establishment of Vehicle-to-Grid (V2G) technology in Germany.
Electric cars such as the Nissan Leaf, with integrated bidirectional charging technology, is able not only to extract power from the grid and store it in its traction battery, but, if necessary, also to feed power back. This is called the Vehicle-to-Grid (V2G) concept.
The bidirectional chargeability of Nissan’s electric car is the foundation for its integration in the pilot project at the Enervie site in Hagen. In combination with innovative, intelligent charging and energy management technology from The Mobility House, the charging and discharging processes can be controlled and monitored.
As one of four Tso’s responsible for the transmission of power in Germany, and thus charged with the stability of the power grid, Amprion is a supporter of the ambitious V2G project. The Tso has defined the technical and regulatory requirements for prequalifying a mobile battery storage unit for the market for primary regulation. Amprion has now approved the Nissan Leaf, as the first electric car, in combination with the control system from The Mobility House, as suitable for this function.
The partnership between CRP Group’s specialized companies and Energica Motor Company to fine-tune the all-electric superbike for the 2019 FIM Enel MotoE™ World Cup goes full steam ahead: an updated version of the MotoE prototype made its first public appearance on-track for testing during the French MotoGP™. The test was carried out by both Loris Capirossi and the Energica official test rider Alessandro Brannetti.
All the solutions have been developed with the support of CRP Group’s know-how. CRP will keep going on collaborating closely with Energica, to achieve optimal results in a very short time.
CRP Technology (the CRP Group’s specialized company in the field of laser sintering and Windform composite materials) is manufacturing aerodynamic parts in professional 3D printing with Windform materials. CRP Meccanica (since over 45 years alongside F1 teams as strategic partner for the production of hi-tech mechanical components) is working on the development of the braking and suspension system.
The know-how of the two companies are supporting the study and development of the new battery.
All these elements have improved the general performance of the superbike, bringing it closer to the preset targets.
The next stop on the road to the 2019 FIM Enel MotoE™ World Cup will be at CRP and Energica’s home GP in Mugello, with a very special rider for the demo lap: the four-time World Champion Max Biaggi.
