Did you know Renault 12 was tested by NASA? – Car book
Badly affected by the 1973 oil crisis, the United States embarked on a relentless search by the end of the decade for solutions that would not only make cars more fuel efficient, but even eliminate fossil fuels altogether, and in this context Renault 12 “Crossed” with NASA.
Sold in the US, the Gallic model was one of those selected as part of NASA’s ERDA project, a project in which the agency responsible for bringing a man to the moon several years earlier sought to discover the commercial viability of electric and hybrid models. …
To this end, the “North American” Renault 12 (easily recognizable by its twin headlights and large bumpers) has been converted to an all-electric model by EVA (Electric Vehicle Associates).
NOT TO LOSE: Renault 4F. The van that revolutionized Formula 1
Founded in 1974 in Ohio, the company was involved in converting combustion engine models to electric vehicles with the support of the US Department of Energy, which, as we told you, wanted to find out if they had electric vehicles. “Legs for walking.”
Or EVA Metro
Without being officially developed by Renault, the electrified 12 changed its name and became known as the EVA Metro. The EVA Metro, equipped with 19 6-volt lead-acid batteries under the hood and in the trunk, weighed 500 kg more than the Renault 12 and weighed 1429 kg on the scales.
To move all this mass, EVA equipped 12 (sorry metro) with a 13 hp electric motor, which allowed it to develop a modest top speed of 90 km / h and accelerate to 50 km / h in 12 seconds. The transmission was controlled by a three-speed automatic transmission.
In terms of autonomy, it mirrored the technology available at the time. Fully charged (which took about six hours on a 220V outlet), the EVA Metro was able to travel 65 to 100 km.
And if you thought it was boring to rent batteries for Renault EVs, know that the batteries of this Renault 12 electric car needed to be regularly refilled with distilled water as a maintenance measure.

Tests
Further evidence of the extraordinary evolution of electric vehicles in recent years is the EVA Metro reliability record in NASA tests (the results of which may consult here).
Tested in 1975 and 1976 (with new and used motors and battery), the EVA Metro impressed in autonomy tests: at a constant speed of 40 km / h, it covered 91 km when the speed increased to 56 km. Its autonomy was 57 km, and even with the speedometer set at 85 km / h, he was able to drive 45 km.
Remember, all of this was achieved before the advent of modern lithium-ion batteries and regenerative braking systems. However, in the area of reliability, things have not gone so well.
In total, the EVA Metro engine had to be changed four times during testing. Even so, it could be seen that archaic 6-volt lead-acid batteries would be able to withstand 45,000 kilometers, which again is not a small amount when you consider that we were in the 1970s.

Despite the positive balance of tests, the EVA Metro was never mass-produced. In total, only seven units were produced (sold to individuals, companies or donated to universities), and only two are known. One is in Canada and the other is in the United States after being restored.

Everything has been delivered. 10 Bugatti Centodieci are already in the hands of the owners
OAll Bugatti Centodieci have been delivered, the Molsheim-based brand said on Monday. Cristiano Ronaldo received the number 07 in October this year. and Bugatti has now revealed that the latest unit – #10 – is already in the possession of its owner.
“The Centodieci combines all the values of the Bugatti brand in an extraordinary package: rarity, innovation, heritage, craftsmanship and unrivaled performance. The production batch of 10 units was so in demand by our customers that it was sold before the Centodieci. was even officially presented,” said Christophe Piochon, president of Bugatti.
This latest example is finished in Quartz White with carbon fiber trim on the bottom and matte grilles. The brake calipers are painted in Light Blue Sport, as is the logo on the rear that refers to the EB110, the iconic Bugatti model that inspired this Centodieci. Inside, the predominant color is also blue, as you can see in the images above.
This block is powered by the same block as the other nine instances. The 8.0-liter W16 with four turbines is capable of developing 1600 hp. In terms of performance, this allows the Centodieci to hit 100 km/h in just 2.4 seconds and reach a top speed of 380 km/h.
Recall that each unit costs the owners eight million euros before taxes.

The first Dacia hybrid. “The cheapest hybrid family on the market”
BUT Dacia revealed this Monday that the hybrid engine has been available since March on the Jogger, the Romanian brand’s model known to be available with a seven-seat variant.
The Jogger Hybrid 140, Dacia’s first hybrid, will hit dealerships in March, but customers can expect and order it as early as January.
The price has been revealed by Dacia and since it’s only available in the seven-seater SL Extreme, it starts at €28,800. The brand claims it is “the most affordable hybrid family car on the market.”
Available in six existing colors to celebrate the launch of this hybrid, there will be a slate gray version, as you can see in the images above.
Equipped with a 1.6 liter four-cylinder petrol engine with 90 hp, the Jogger is also powered by two electric motors (a 50 hp engine and a high-voltage starter-generator). The total power is 140 horsepower. The electric transmission is automatic, four-speed, connected to an internal combustion engine, and two speeds are connected to an electric motor. This combined technology was possible, according to Dacia, only due to the lack of clutch.
Combined with the energy recovery levels of the 1.2kWh (230V) battery pack and the efficiency of the automatic transmission, regenerative braking delivers all-electric traction on 80% of urban journeys and saves up to 40% of fuel compared to a combustion engine vehicle.

See how Tesla tests its electric Semi truck in the worst-case scenarios
Tesla has finally been able to bring its long-awaited Semi to market. This electric truck promises to revolutionize transportation and bring all the unique characteristics of this type of electric vehicle to this class of vehicles.
Now that the first units have been delivered, there is hope that they will finally be mass-produced and reach more transport companies. With so many promises to be kept, a new video is now emerging showing Tesla testing its Semi truck under worst-case scenarios.
Tesla Semi is already on the market
Like all Tesla electric vehicles, Semi follows the same line of creating a unique design associated with a platform with the most modern technology available. The proof is in what was presented to the public and surprised most people.
To prove the quality of this new proposal, Tesla published in your LinkedIn account new video. In it, he reveals some of the testing he's done to determine the strength and quality of the Semi's design and its (potential) durability.
Tests to prove its durability
It has been revealed that the Tesla electric truck is subjected to numerous tests and its application in the worst scenarios that drivers may face. It doesn't stop at the ruggedness of the Semi's designs, but goes further and focuses on the motors and batteries themselves.
This is the proof that many have been waiting for to ensure that this new proposal is not limited to a lot of autonomy. Its resistance is great and will provide greater durability, further enhancing the Semi's value and performance.
high quality electric truck
Tesla has already showcased the Semi's quality with a video showing its truck driving roughly 500 miles on just one charge. The big news here is that he managed to make this long journey with a maximum load of about 37 tons.
Now Tesla remains to widely place the Semi on the market. At the moment, only a few companies have access to this new product, with a very long list of pending deliveries, who want to start mass-using this electric truck offering.
