Buick has launched an app for iOS and Android smartphones to help raise MPG awareness. A trio of eAssist Fuel Efficiency smartphone games are packaged into a single app that’s now available to download for free and offers a fun way to hone your driving techniques in order to maximize fuel economy.

The three games are titled “Regeneration Road”, “Roll and Boost”, and “Wind Tunnel Tester.” Regeneration Road focuses on the regenerative braking featured found on Buick eAssist vehicles which helps capture and store energy when a vehicle is braking in order to recharge the lithium-ion battery. Players must make it through the town without running out of fuel while avoiding pedestrians along the way.

The second game, Roll and Boost, has a focus of distance and not speed with battery management being the main priority. By using the energy stored from braking strategically, an emissions-free boost of acceleration can be had and using that energy at optimal times is key to Roll and Boost.

Lastly, Wind Tunnel Tester allows players to put on their automotive engineering hat. Sit there and tweak the vehicle’s length and width on the screen, understanding how the sleek and modern shapes of Buick vehicles help maximize aerodynamics and ultimately fuel efficiency.

eAssist can be found on the Buick LaCrosse and Regal models and aids the performance of a fuel-efficient 2.4L gas engine to achieve 36-mpg. eAssist also allows the gas engine to turn off completely while the car is sitting idle.

“The driving force behind eAssist’s development was to make great vehicles like the LaCrosse and Regal even better,” said Dan Cottrell, General Motors assistant chief engineer for the eAssist powertrain. “With eAssist we can improve both vehicle performance as well as fuel economy.”
