A number of sensors have been developed to detect excessive alcohol consumption and prevent impaired drivers from starting their vehicles. The application has primarily been incorporated as a punitive step for repeat offenders. However, when a carmaker proposes a concept, the possibility of OEM use gets a step closer to reality — a step which could prevent or reduce deaths and accidents from drunk driving. Saab's Alcokey concept combines an alcohol sensor with engine immobilizer technology. A key fob with an integrated mouthpiece provides a sample of the alcohol content in the driver's breath to a small semiconductor sensor. An excessive level of alcohol prevents the engine from starting similar to the immobilizer in existing anti-theft systems.

A new method of modeling how they are created with chemical vapor deposition (CVD) could reduce the cost of carbon nanostructures used for for research and commercial applications, including advanced sensors and batteries.
BMW has already incorporated more than 10,000 3D-printed parts in the Rolls-Royce Phantom and intends to expand the use of 3D printing in its cars even more in the future. Meanwhile, Daimler has started using additive manufacturing for producing spare parts in Mercedes-Benz Trucks.
