BAS hybrid

[1] It operates similarly to other mild hybrids with a start-stop system, in that it shuts down the engine as the vehicle comes to a stop and instantly restarts it when the brake pedal is released.

Although unable to operate in pure all-electric EV mode, THS-M improves city and highway fuel efficiency over non-hybrid versions.

The first production model equipped with THS-M was the eleventh generation Toyota Crown Royal Saloon Mild Hybrid, introduced in August 2001, combining the system with a 3.0 L 2JZ-FSE straight-six engine.

[2] It was followed in October 2002 by the Toyota Crown Sedan Super Deluxe Mild Hybrid, which combines the system with a 2.0 L 1G-FE engine.

[8] Citing supplier issues and slow sales, GM has relegated the 2010 model year BAS hybrids to "fleet only" status.

[9] At the LA Auto Show, on November 15, 2010, General Motors announced that it would be releasing an all-new version of the BAS system available in the 2012 Buick LaCrosse.
