Leading auto parts supplier Mahle has announced a groundbreaking ‘Superior Continuous Torque’ (SCT) motor for electric vehicles capable of delivering more than 90% of its peak power continuously without overheating – and it will run without magnets.
Electric motors, unlike internal combustion engines, often have separate peak and constant (or rated) power ratings. This is because running them for long periods of time can generate enough heat to damage components, so manufacturers build in thermal limiting systems that reduce power output to a constant level when they start to overheat.
For example, the motor in the Ox Patagonia electric motorcycle at 11 kW peak power is so poorly cooled that it can only handle 6 kW continuous power, which is 55% of peak power. On the other hand, the new EMCE engine from Energica develops a peak power of 126 kW, but can handle a constant power of 110 kW (87% of peak power) thanks to a very efficient cooling system.
Mahle says the new SCT motor takes things to the next level, delivering more than 90% of peak power at a constant power rating. It uses an innovative oil cooling system. If necessary, the heat removed can be collected for use elsewhere around the vehicle or removed through a radiator.
The result, the company says, is an exceptionally compact, lightweight and efficient electric motor capable of handling sustained high power situations that previously required much larger motors with much higher peak power ratings. It’s, according to Male, an engine that can pull a large electric truck over a long, steep mountain pass without losing power, or take the brunt of a race track in a sports car.
Smaller engines also bring other benefits: they require fewer materials, lower costs, and weigh less, which increases the power-to-weight ratio for sports cars, as well as the payload of a heavy tractor. Mahle claims the SCT engine is suitable for cars, trucks, construction vehicles and tractors.
The SCT engine will be presented at IAA Transportation in Hannover this September.
Even before the launch of Dojo, the Tesla supercomputer has 7360 Nvidia A-100 graphics accelerators and is ranked seventh in the world
Tesla AI Infra & AI Platform manager Tim Zaman said the electric vehicle maker now has the world’s seventh largest supercomputer by number of GPUs. And this is before the launch of the Dojo supercomputer.
Tim Zaman confirmed that Tesla has upgraded its supercomputer to 7360 A100 (80 GB) GPUs. This makes the Tesla supercomputer one of the largest in the world in terms of the number of GPUs.
The A100 GPUs are made by Nvidia, where Zaman worked before joining Tesla. Each processor has 80 GB of graphics memory and has a bandwidth of 2 TB per second.
Tesla’s current supercomputer is the forerunner of the Dojo. Interestingly, Tesla noted last year that the company’s supercomputer, even before Dojo, was already the fifth most powerful in the world with the 5760 Nvidia A100. The company has since added about 1,600 GPUs to the system.
The Tesla Dojo supercomputer is developed in-house, so instead of the Nvidia A100, it will use a custom Tesla D1 chip that will be supported by FP32, BFP16, and CFP8. Dojo will be optimized for machine learning workloads, specifically Tesla Autopilot and Full Self Driving.
Rostec showed the latest sensors based on various physical principles for detecting infantry and ground vehicles
Rostec for the first time showed the intelligence and signaling complex for covert surveillance 1K144-E, which includes sensors based on various physical principles. They are able to detect infantry and ground vehicles of the enemy, remaining completely invisible.
The complex includes seismic, infrared and magnetometric sensors up to 20 cm in size and weighing 150-600 grams. They are buried in the ground, camouflaged on the ground and provide continuous operation from built-in batteries for up to 30 days.
The system captures moving objects, determines the direction of their movement, counts and classifies them by type: wheeled vehicles, tracked vehicles or manpower. The complex is able to detect an infantryman within a radius of 30 m, wheeled vehicles – up to 120 m, a tank or infantry fighting vehicle – up to 200 m. You can install such sensors in a matter of minutes.
The data is displayed on the operator’s monitor in the form of an electronic map of the area with indications of the location of sensors and detected objects. The system is already being produced by the Sozvezdie Concern (part of Roselectronics).
At the Army forum, for the first time, we present a full-scale sample of the export version of the 1K144-E (TAS3) complex. This is an advanced covert remote surveillance solution for assessing the situation at controlled borders. The complex uses sensors operating on various physical principles, which ensures the reliability of the transmitted data.

This is Chery Tiggo 9. The latest crossover was shown from all sides
After the appearance of the first spy photos of the flagship crossover Chery Tiggo 9, renders were created to more accurately examine the expected new product.
The first information about Chery Tiggo 9 appeared last year, the car passes under the model number T26. It will get premium retractable door handles and a new design.
According to Chery’s internal documentation, the T26 will be built on the T2X platform, and its dimensions will only slightly exceed the Tiggo 8 Pro. The exact dimensions will be 4780 x 1920 x 1700 mm with a wheelbase of 2800 mm. Chery Tiggo 9 will be available in 5-, 6- and 7-seater versions. It will be equipped with 1.6- or 2-liter turbo engines, as well as a 7-speed “robot”. The drive can be front or full.
Chery is also preparing a crossover codenamed T26J, which will be a sports modification of the Tiggo 9 with a 5-seater saloon, a 2-liter engine and an 8-speed automatic transmission.
The front of the Chery Tiggo 9 will receive a frameless grille reminiscent of Omoda 5. The headlights are distinguished by LED running lights and a block of high and low beam located under them. Chery Tiggo 9 turn signals are represented by horizontal stripes that are located under the headlights. Fog lights and an adaptive cruise control radar can be seen at the bottom of the front bumper.
At the rear, Chery Tiggo 9 has a single block of lights. Stoplights and turn signals are located in the horizontal elements below them.
The renders were created by the same insider who first published images of Chery Arrizo 8, which ended up being very close to reality.
