Supercar Lamborghini: the four-wheel drive makes its debut in full electric mode

Lamborghini has released the first technical info concerning the new 12-cylinder supercar LB744 that will be soon unveiled integrally. The first super-sports hybrid plug-in V12 HPEV (High Performance Electrified Vehicle) will be then ready to make its debut in the year of the brand’s 60th anniversary. The car’s goal is defining a new paradigm in terms of performances, sport character and drive pleasure, also thanks to a new architecture and a powertrain exceeding 1000 HP, combining the power of a brand-new thermal motor with three electric motors and the first dual-clutch gearbox that makes its debut on a 12-cylinder Lamborghini.
Compared to the previous powertrain, V12 has been rotated by 180° and is no longer equipped with the transmission in the front part but instead downstream the engine block, connected with the only rear wheels. The physical transmission shaft is replaced by the lithium 3.8 kWh battery that powers the electrified front axis, rechargeable at 7 kW, taking around half an hour to fill up.
The overall weight is 193 Kg, which includes the integration of a new fundamental component in the vehicle’s hybrid architecture, the rear e-motor, which has a maximum power of 110 kW and maximum torque of 150 Nm.
Placed above the gearbox, the electric unit performs the tasks of starter and generator, besides supplying energy to the two front electric motors through the battery positioned under the tunnel, acting as boost in the full electric drive modality and allowing the zero-emission four-wheel drive, directly acting on the rear axle. The tasks vary depending on the drive modality inserted, through an uncoupling mechanism. For that reason, it is equipped with dedicated synchronizer, which allows the connection to the double-clutch gearbox. When it supports the action of the V12, the e-motor is in the position that is defined P3, with electric motor downstream the gearbox, whereas it shifts to P2 to recharge the battery when stationary or at low speeds and it acts also as starter motor.
Electric powertrains improve the power delivery at low revolutions and can also make the new LB744 a fully electric-traction car, reducing the overall CO2 emissions by 30% versus the Aventador Ultimae.

Electric traction for Rome Police

The uniform of the Local Police Corps of Rome Capital is worn by 40 Jeep® Renegade 4xe vehicles, among the best-selling-models in Italy in the SUV LEV B-segment, the one of electric low-emissions or Plug-In Hybrid cars.
The fleet is characterized by SUV with Plug-In Hybrid technology and cars are equipped with 1.3 litre turbocharged four-cylinder engine and with rear electric motor, for an overall power of 190 HP. Due to electrification, Renegade – like the Jeep range in its whole – further improves its legendary capability, through the high driving torque ensured by the electric motor and the possibility of adjusting it with extreme precision in starting phases an in the most challenging off road drive, when a very low transmission ratio is necessary. With the new integral electric traction technology, the traction to the rear axle is not provided by the transmission shaft but by dedicated electric motor. This allows releasing the two axles and managing the torque delivered independently and better than with a mechanical system.

Flying will be as easy as drinking a glass of water

Recently, Peter Ternström, co-founder of Jetson company, with headquarters in Stockholm, has revealed that piloting one of his personal electric aircrafts is as easy as it seemed in cartoons and that learning needs just five minutes. The delivery of his Jetsone One will start from the end of 2023 and therefore what is announced is a great revolution in the airplane transport. The units already sold, at a cost that approaches 100,000 dollars, are already almost 500.
«It is super-intuitive. We have developed a fly-by-wire system that helps the pilot with functions like the automatic hovering, the stable flight and landing».
Let us take a step back: expert in the luxury car industry, Ternström has collaborated with the aerospace engineer Tomasz Patan to launch in 2017 the Jetson drone, equipped with a single-seat architecture “to make the flight available for all”. In fact, the regulations for that class of aircrafts do not impose flights close to airports or crowded areas and there is neither the need of a pilot licence. The drone weighs 86 kilos, it has an aluminium frame with eight electric motors that allow it to go on flying for about 20 minutes with maximum speed limited by the software of 100km/h. Pilots, who can weigh 95 kilos maximum, control the drone by means of joystick and accelerator.

Flight with hydrogen electric motor? The partnership between H3 Dynamics and Hylium Industries

Joining their forces, the two companies H3 Dynamicsm with headquarters in France, and Hylium Industries, with head office in South Korea, have developed a first unmanned aircraft based on liquid H2, weighing just 25 kg, in a first attempt of transatlantic flight powered by a hydrogen electric motor.
Spotlights are cast on the solutions of storage and liquefaction of liquid Hylium hydrogen, and the nacelles with distributed hydrogen electric propulsion, ultra-light fuel cells, and the new hydrogen drone refuelling stations.
It is worth reminding that in November 2021, H3 Dynamics completed the first operating prototype of hydrogen propulsion nacelle and in July 2022 the first distributed pod system, installed on an aircraft on small scale, took off from “Hub Drones – Systematic” airport, in the outskirts of Paris. The autonomous nacelle approach by H3 Dynamics satisfies those technical, safety and cost problems that hydrogen aircraft developers might have to face in the future: positioning more compact hydrogen and fuel cells on a series of nacelles with collaborative propulsion under wings.
«Not only our first priority is safety, but we do not want that hydrogen takes away space for revenue-generating passenger and freight transport. The distribution of compact systems solves technical inconveniences such as the thermal management and increases safety through the multiple redundancy», affirmed Taras Wankewycz, founder and CEO of H3 Dynamics.

New steps towards electric boating

The cooling system is entrusted to a closed circuit that avoids the contact of whatever internal component of the motor with the sea water, protecting it against corrosive phenomena. The Chinese manufacturer’s promise is a very competitive price on the European market, too.

Four-wheel drive for Nissan X-Trail electric SUV

X-Trail is the last Suv presented by Nissan, in the four-wheel drive version it is pioneer in being equipped with the exclusive e-4ORCE and e-Power systems.
The new Nissan e-4ORCE technology is the evolution of the four-wheel drive on electric and electrified vehicles. The name allows guessing what are the novelties hidden behind this change of pace: a fully electric traction, 4 for the wheels that are moved by the two electric motors.
Nissan engineers have focused on three aspects: the joint operation of motors, frame control technologies and, last but not least, the study of case movements (roll, yaw and pitch) to minimize them in comparison with a conventional thermal vehicle.
The 4ORCE system is composed by two electric motors, one for each axis. The motor on the front axle can develop 150 kW (204 HP), the one on the rear axle 100 kW (136 HP), for 157 kW (213 HP) overall. They are managed by a sophisticated control unit able to adjust driving force and braking action on each single wheel.
Moreover, the motor allows the Suv to shift from 0 to 100 km/h in 7 seconds and, compared to a mechanical 4Ă—4 system, the drive regulation on the 4 wheels is 10,000-time higher, as well as reaction times.
The torque is constantly distributed on the two axles and having mounted two equivalent electric motors in terms of weight allows a mass distribution that approaches 50:50, synonym of more frame stability and better handiness.
