This SAE Recommended Practice presents service brake performance requirements for brake systems of all combinations of new passenger cars and new trailers (braked or unbraked) intended for roadway use (excluding special-purpose vehicles such as ambulances, hearses, etc.). Acceptable performance requirements are based on data obtained from SAE J134.

A 24-hour battle of speed and efficiency At Le Mans this month, amped-up hybrid prototype racecars from Audi and Toyota face a revamped Porsche 919 hybrid, while Ford hopes to recapture glory with its new GT-R. Pushing the ICE forward, gradually Emergent technologies from BorgWarner, Eaton and Mahle aim for greater efficiency in gasoline and diesel engines. Smile, you're on Magna camera! Magna Electronics is rapidly expanding production of its made-in-U.S.A. onboard cameras to keep pace with booming OEM demand for safety and vehicle-autonomy vision-systems technology. Multi-material body solutions: Possibilities and manufacturing challenges The body-in-white is a prime target for lightweighting and many automakers are pursuing unique and effective multi-material approaches, but improved design tools and processes might yield greater gains.

Lightpipe design According to Breault Research Organization, any off-highway instrument or control that needs illumination is a candidate for a lightpipe to take light from where it is generated to where it is needed. The biodiesel choice Experts from the Natural Biodiesel Board believe it is time to consider alternatives to the current fuel structure. One solution to rising fuel prices is the pursuit of biodiesel fuels. Understanding machining difficulties in gray iron Bosch Braking Systems' engineers look more closely than usual at iron brake rotor samples to give new insights into critical characteristics of the material. Caterpillar mining for customers With commodity prices low, Caterpillar wants to make mining as productive an enterprise as possible for customers.

The electric vehicle business will approach a massive $500 billion in 2025 with the traction motors segment capturing over $25 billion. Traction motors propelling land, water and air vehicles along can consist of one inboard motor or - an increasing trend - more than one near the wheels, in the wheels, in the transmission or ganged to get extra power. Complex trends in this industry are explained with this updated report, and future winning suppliers are identified alongside market forecasts. The information is especially important as hybrid vehicles may have the electric motor near the conventional engine or its exhaust, and this may mean they need to tolerate temperatures never before encountered in pure electric vehicles. Motors for highly price-sensitive markets such as electric bikes, scooters, e-rickshaws and micro EVs avoid the price hikes of neodymium and other rare earths in the magnets.

The electric vehicle industry - land, water and air - is rapidly rising to become a market of over $533 billion by 2025. Some run entirely on harvested energy as with solar lake boats. Others recycle energy as with regenerative braking of cars, buses and military vehicles harvesting kinetic energy. Others use different forms of harvesting either to charge the traction batteries, or to drive autonomous device. In some cases, harvesting is making completely new forms of electric vehicle possible such as "glider" Autonomous Underwater Vehicles (AUVs) that can stay at sea for years, gaining electricity from both wave power and sunshine. Multiple forms of energy harvesting on one vehicle are becoming more common from cars to superyachts.
