Mate Rimac, CEO of supercar makers Rimac and Bugatti, has commented on Elon Musk’s claim that the new Tesla Roadster is going to accelerate from 0 to 60 mph in less than 1 second with thrusters.

He sees some problems with it.

Tesla’s next-generation Roadster was first unveiled back in 2017. It was first supposed to come in 2020, but it has been delayed every year since.

Last year, Elon Musk said that it would come in 2024.

Last month, the CEO said that he had a design meeting about the new Roadster, and they decided to “radically increase the design goals for the new Tesla Roadster.” Musk said that the vehicle is delayed again until next year, but he said that Tesla plans to unveil an updated version later this year.

Musk again claimed that the vehicle would achieve sub-1-second 0 to 60 mph acceleration with cold air thrusters built by his rocket company, SpaceX.

Rimac has been keeping close track of the Roadster program as its Neverra electric hypercar is achieving similar performance that Tesla has been originally claiming for the Roadster.

After Tesla unveiled the prototype of the new Roadster, Rimac unveiled a new version of its supercar with similar specs.

The Croatian electric supercar manufacturer is also now in a better than position than ever to compete with Tesla after Porsche invested in the company and had its founder and CEO, Mate Rimac, takeover legendary supercar maker Bugatti.

Recently, Rimac was asked on Facebook about Tesla’s claim of sub-1-second 0 to 60 mph acceleration in the new Roadster.

He said that Rimac did the simulation. He thinks it’s possible, but it creates some weight issues:

It is possible with thrusters. We did the simulation. The problem is that you release the air in 2-3 seconds, and then you have a lot of dead weight that you are carrying around (tanks, compressors, valves, nozzles, etc.). Same with fans – they just give you more grip, but you need something like 30.000 Nm on the wheels to accelerate below 1 sec 0-100 km/h, which means you need massive motors, inverters, gearboxes, driveshafts, etc. Plus, the car has to be super light as otherwise you can’t create a lot of excess downforce with the fans as the tires would be overloaded very fast with any kind of car with “normal supercar” weight, especially electric. And then again you are carrying the weight with you when you are not doing 0-100 km/h. So thrusters are really the only way to go. But it brings a lot of downsides as well.

It sounds like Rimac is not sold on the idea of putting cold air trusters in its supercars.

Can Tesla prove them wrong?

Electrek’s Take

It sounds like a fair assessment. There is a lot of hardware in the car, almost entirely just to accelerate faster, which you will likely not be able to do on public roads with the thrusters.

The rest of the time, it will make your car’s performance worse with the added weight.

Originally, Tesla talked about the new Roadster having over 600 miles (965 km) of range. That was one of the things I was most excited about with the Roadster.

However, since then, Musk has said that Tesla is not interested in making cars with more than 400 miles of range and interestingly, it’s for a similar reason as the problem highlighted by Rimac. People rarely drive more than 400 miles in one go and the rest of the time, you are carrying a super large and heavy battery pack for no reason.

With his recent update on the new Roadster, Musk didn’t mention the range. It will be interesting to see if 600 miles of range is still in the plans for the new Roadster.

Porsche kicks off Macan EV production at its newly upgraded plant

After investing nearly $1 billion over the past several years, Porsche launched electromobility at its production site in Saxony. The investment was designed to expand the facility so Porsche could ramp up Macan EV production.

On Tuesday, the company announced the official start of electromobility at its production site in Saxony, Germany.

Porsche has invested nearly $1 billion (600 million euros) to upgrade the facility to prepare it for Macan EV production. New additions include a new body assembly line. Porsche says production of the new Macan is currently being ramped up.

“At Porsche, we’re convinced that electromobility is the future,” CEO Oliver Blume explained. Following the Taycan, the Macan is Porsche’s second all-electric vehicle.

Despite this, Porsche wants to “remain flexible” by making gas, hybrid, and electric cars on the same production line.

“In production at Porsche, we have implemented the ‘smart, lean and green’ approach at all our factories,” Porsche executive board member for production Albrecht Reimold said.

“This means that we have the vision of an intelligently connected factory with the lowest possible environmental impact.” The Porsche Macan is produced with a carbon-neutral balance sheet in Leipzig.

Porsche is working toward a carbon-neutral balance sheet across its entire value chain for new cars built by 2030.

Porsche will begin deliveries of the new Macan EV in the second half of the year. Blume boasted in March, “We already have 10,000 orders, and these customers haven’t even been able to drive the car yet.”

Meet the all-electric Macan

The Macan EV is available in two options: the Macan 4 and Macan Turbo. The Macan 4 generates up to 402 hp (300 kW), while the Turbo model packs up to 630 hp (470 kW).

With that, the Macan 4 can sprint from 0 to 60 mph in 4.9 seconds, while the Turbo model takes just 3.1 seconds.

As the first Porsche based on its new 800V PPE platform, the Macan EV can charge from 10% to 80% in under 21 minutes (with 270 kW charging).

Inside, the electric Macan gains luggage space over the gas model with up to 18 cu ft capacity behind the rear seat.

Porsche equipped the new Macan EV with its latest-gen infotainment, including a 12.6″ curved instrument cluster and 10.9″ central display. For the first time, passengers are offered a personal 10.9″ touchscreen.

The new infotainment is based on Android Auto OS and compatible with Apple CarPlay. The starting price for the Macan 4 is $78,800, while the MSRP for the Macan Turbo is $105,300.

Both do not include a $1,650 delivery fee. While EPA range figures will be released closer to deliveries, Porsche says the Macan EV 4 gets up to 381 miles (613 km) WLTP range. The Turbo version gets up to 367 miles (591 km).

Orders for Porsche’s new electric SUV are open now. You can use our link to view deals on the new 2024 Porsche Macan EV and Macan Turbo in your area.

Tesla loses a top AI lead

Tesla loses a top AI lead

Tesla has lost a top AI engineer in charge of “planning, imitation learning & RL team for Tesla AI” amid a broader talent exodus.

Over the last few weeks, Tesla has been conducting several major waves of layoffs throughout its entire organization.

On top of the layoffs, we recently reported that some Tesla employees are leaving the company due to low morale.

There appear to be a clear exodus of talent at Tesla at the moment.

Another example is Paril Jain.

Jain spent the last 9 years at Tesla where he became an important part of Tesla’s autonomous driving effort.

Most recently, he was tech lead for “Planning, Imitation Learning & RL team for Tesla AI.” He listed the responsibilities of his team on LinkedIn:

  • Build the Foundation Models for autonomy that can scale to vehicle as well as humanoid platforms
  • Leverage millions of miles of driving data and interventions to build a robust and scalable end-to-end learning based self-driving system.
  • Research on cutting-edge techniques in generative models, reward models and reinforcement learning to improve the safety and comfort of our driving models.
  • Experiment with synthetic data generation and network driven data collection approaches to enhance the diversity and quality of training data
  • Ship production quality, safety-critical software to the entirety of Tesla’s vehicle fleet

Today, he announced that he is leaving Tesla to co-found ‘The Bot Company’, a startup to build robots founded by Kyle Vogt, co-founder of Twitch and Cruise.

Super pumped for the next phase of building. We have spent the last decade building robots that give people some of their time back, and it’s time to take it to the next level with The Bot Company.

Jain has good words for the Tesla team:

As for Tesla – it has been an incredible 7 years building the best self driving product on the market. You’ll love the upcoming versions of V12 and Actually Smart Summon. The team is on an amazing trajectory to continue pushing forward more improvements on the road to being driverless

Nonetheless, Tesla’s autonomous driving team appears to have lost another engineering leader.

Electrek’s Take

As I have been saying for a while, Tesla’s biggest strength has always been its capacity to attract and retain talent. The company always scored in the top places engineering students want to work.

I think the way Elon handled the latest round of layoffs, and the talent exodus that is happening now, shows that this capacity is eroding.

I hope that they can turn this around.
