Renault 5 E-Tech Electric Roland Garros

Leave a comment

For years, Renault has produced special editions of its Renault 5 model inspired by one of the biggest tennis tournaments in the world, Roland Garros. The same path was continued with the new electric version of this model, the Renault 5 E-Tech Electric.

The special edition will be offered in three body colors: Pearl White, Midnight Blue, Starry Black and Matt Slate Gray. Each car will be equipped with a Satin Black roof trimmed with chrome trim, featuring Roland Garros logos and a St. Andrew’s Cross pattern inspired by the stadium’s architecture. There are also 18-inch Ecrou Diamond Black wheels with Matt Slate Gray center caps.

Inside, the seats are covered in recycled textiles, inspired by the fabric used to make sports equipment. There’s also plenty of Roland Garros logos, even on the e-pop shifter shaped like a tennis racket handle. Also, the dashboard lighting displays the inscription “Roland Garros Paris” and pays homage to the clay surface of the court.

When it comes to the powertrain, the 40 kWh battery version is powered by an electric motor with 95 hp (71 kW) and 159 lb-ft (215 Nm) of torque or 120 hp (89 kW) and 166 lb-ft (225 Nm) of torque, which is enough to accelerate from 0 to 100 km/h (62 mph) in 10 seconds. It weighs 1,350 kg. The slightly heavier version (1,450 kg) is equipped with a 52 kWh battery, and is powered by an electric motor with 150 hp (110 kW) and 181 lb-ft (245 Nm) of torque. It reaches 62 mph in 7.5 seconds with a top speed of 150 km/h (93 mph) and a range of 400 km.

KAIST has developed a battery that can be charged in seconds

Leave a comment

At a time when car manufacturers are struggling with production costs as well as battery quality, many of them are trying to find the best solution. Lithium-ion batteries are currently the most used on the market, but a new type of battery that is much more efficient has been talked about for a long time. These are sodium batteries that are more cost-effective and more sustainable because they can be produced almost entirely without rare metals. However, scientists from the Korea Advanced Institute of Science and Technology (KAIST) have developed a hybrid battery that can be charged in a few seconds.

The journal Energy Storage Materials published an article about a new type of battery that can be fully charged and discharged in just a few seconds. This was achieved thanks to the use of materials used for supercapacitors (a type of an electrochemical energy storage systems which have great power density and specific capacitance), known for high charging speeds, but they can only store a very small amount of energy.

It is believed that the combination of the best properties of the sodium battery and the supercapacitor could be an advantage in the production of batteries that, in addition to the enormous charging speed, would have a longer range than the current ones. Thanks to the high power density, the vehicles could also use significantly more powerful electric motors.

Sodium batteries are already in use, but they do not provide a short range (250 km). JAC Yiwei EV is the first car equipped with sodium-ion batteries.

Keyvany Kytoro based on Lamborghini Revuelto

Leave a comment

Lamborghini Revuelto is one of the most powerful cars of the Italian manufacturer, with outstanding aerodynamics and impressive performance. However, there are always those who think they can make this super powerful car better. One of them is the German company Keyvany, which presented the Kytoro project based on the Lamborghini Revuelto.

Kytoro brings a new front bumper, a new bonnet, additional air vents, wings and creases, as well as a double splitter. There are also new openings on the fenders, new housings for the side mirrors and different wings on the door sills. At the rear, there are additional ventilation openings on a massive diffuser and a fixed rear wing. All components are made of carbon fiber. The car is painted in Arencio Borealis and some components are made of exposed carbon.

So far, the Keytoro package exists only in digital form, but the company is already accepting orders. The price has not been publicly announced.

Under the bonnet is still the 6.5-L L545 naturally aspirated V12 engine combined with an electric motor with a total output of 1,001 hp (746 kW) 783 lb-ft (1,062 Nm) of torque. Power is sent to all wheels via an 8-speed Graziano dual-clutch automatic transmission. It reaches 100 km/h (62 mph) in 2.5 seconds with a top speed of 350 km/h (217 mph).
