Created an oil-cooled automotive electric motor that does not overheat and constantly develops more than 90% of its peak power
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.
One of the best-selling cars in the world has changed generations. 2023 Toyota Yaris unveiled
Toyota presented to the European public an updated fourth-generation Yaris hatchback with an expanded range of hybrids, improved safety features and an updated infotainment system.
The changes start with the new Hybrid 130 transmission, which is offered in addition to the existing Hybrid 115 configuration. Both hybrid systems are equipped with a 1.5-liter engine, but the new version features a new transmission with a more powerful electric motor and improved software. As the name suggests, the combined power increases to 130 hp. (96 kW), and the torque with the new engine increases from 141 Nm to 185 Nm.
The most significant advantage of the new hybrid will be felt during overtaking: the acceleration time from 80 km/h to 120 km/h is 7.5 seconds. The acceleration time from 0 to 100 km / h has been reduced by half a second and now stands at 9.2 seconds.
Toyota upped the standard active and passive safety package included with the Yaris by introducing new features called the Toyota T-Mate. The vehicle’s collision detection system has been upgraded to detect motorcycles as well as other vehicles, pedestrians and cyclists.
There is a low speed acceleration suppression function that prevents the driver from accelerating hard when the vehicle detects a vehicle ahead. There’s also a new emergency stop system that works when Lane Trace Assist is activated. If the driver falls asleep or becomes ill while driving on the highway, the system will sound a warning. Also, the car can smoothly stop, activate emergency lights and unlock the doors.
The new Proactive Driving Assist feature slows the car down if the driver releases the accelerator pedal and there is a car or a curve ahead. There is also a steering assist system that adjusts the force on the steering wheel. Software updates will be downloaded while driving and installed at a convenient time.
The 2023 Toyota Yaris features a new infotainment system. One of the new features is a customizable driver’s instrument display with four options to choose from. The screen size will depend on which model you choose, from 7 to 12.3 inches. The size of the infotainment screen also depends on the model: 9 or 10.5 inches.
There’s Apple CarPlay and Android Auto wireless functionality, with Toyota improving the Yaris voice recognition software to manage climate control.
For the first time, the Yaris will be offered with a digital smart key that can use an Apple or Android phone to remotely lock or unlock the vehicle, as well as control climate control and alarms. However, this functionality will only be offered if you are willing to pay for an annual subscription to the service, although Premiere Edition will come bundled with an annual subscription.
Pricing will be announced closer to launch.
2024 Audi A6 and Audi A7 unveiled
Audi is gearing up to revamp its lineup soon with new names for many models, but the A6 and A7 models remain in the lineup for the time being and receive several updates for the 2024 model year.
Changes include a redesigned front end, new wheel designs, and new features that come standard on the machines. This also applies to the S6, S7 and A6 Allroad models.
The front grille and bumpers of the A6 and A7 have been redesigned and there are more differences between the standard version and the S Line package. Buyers will have wheels ranging in size from 17 to 21 inches in Europe, while in the US they come standard with 19-inch wheels. The color palette will also change.
Parking assistance is now a standard feature. Various appearance versions are available, including basic, advanced, and S Line. New interior trim options include optional wood and microfiber trims, but Audi has yet to share photos of the updated cabin.
The A6 comes standard with a 2.0-liter turbocharged inline-four with 261 hp. and a 3.0-liter turbocharged V6 with 335 hp. The A7 comes standard with a V6, while the S6 and S7 have a more powerful 444-horsepower turbocharged 2.9-liter V6.
Prices will be announced later, sales will start at the end of the year.
More spacious than the CR-V and with a consumption of only 1.75 liters per 100 km. New crossover Honda Breeze ready for release in China
The next-generation Honda Breeze mid-size crossover has been on sale in China since December last year, and hybrid versions are now certified – regular and plug-in hybrid. This is equivalent to obtaining a production permit.
Externally and in terms of equipment, the hybrid Breeze is no different from the usual gasoline version, but the power plants, of course, are different: in both cases, a 2.0-liter engine is used, supplemented by an electric motor. The maximum output of the conventional hybrid power plant is 150 hp, the maximum output of the plug-in hybrid version is 184 hp. The average fuel consumption of the plug-in hybrid version is 1.75 liters.
Dimensions Honda Breeze – 4716 x 1866 x 1681 mm with a wheelbase length of 2701 mm. It’s the size of the Breeze’s wheelbase that surpasses the CR-V, so the car is slightly roomier inside.
