The manual transmission faces an uncertain future. Increasing emissions standards, future safety technology, and dwindling take rates could spell its demise. But a new patent shows Toyota gives a shift, as we like to say, and it could give the manual gearbox an extended lease on life.

Roadshow discovered the Toyota patent for a "Controller for vehicle and control method for vehicle." Translation: the technology allows for the engine to return to idle while coasting in a car equipped with a manual transmission. In turn, it could help raise fuel economy in cars equipped with a manual transmission, which are often outdone by modern automatics with more gears.

Seems like a neat concept, but as Road & Track points out, the technology harkens back to technology used by Saab in the 1960s. The now-defunct Swedish automaker used a freewheel mechanism to help with lubrication issues found in…
