Mercedes engine re-design powers it to top of F1


an article on alphr.com detailed the work that mercedes did in designing its newest engines, which incorporated improved thermal management, turbochargers from its line of diesel trucks, and an energy recovery system (ers) related to plug-in hybrid vehicles. the engine gave mercedes an edge that saw its drivers, lewis hamilton and nico rosberg, climb to the top of the formula one standings.

“designed in response to changes in engine rules, the mercedes hybrid pu106a is the fruit of a concentrated period of research, development and learning,” wrote curtis moldrich for alphr.com. “powered by a synergy of turbo, electric motor and internal combustion technology, it’s the most complex, efficient and powerful engine mercedes has ever made.”

 

the author spoke with andy cowell, the managing director of mercedes amg high performance powertrains, who helped design the new f1 engine, and went through many of the3 features that turned the mercedes engine into the leading design in the world’s most popular racing circuit.

 

among the many changes that mercedes implemented was a turbocharger that captured waste exhaust gases to turn a compressor attached to the engine. this forced air into the engine to increase pwer and efficiency.

 

moldrich wrote, “although mercedes uses turbos in its road cars, it was daimler’s truck division that proved the most useful to cowell and his team: the huge amounts of power involved in the f1 engine meant they were a better fit.”

 

to manage turbo lag from the larger turbocharger that was put into the f1 engine, mercedes turned to its electric vehicle technology for a solution. the electric motor would “spin up the turbo well before the exhaust gas arrived.” this avoided slow response time from pressing the accelerator and the potentially uncontrolled acceleration that would follow. as the author noted, this may be annoying when on the road, but on the track the results could be disastrous.

 

another hybrid component to the new engine was an ers that could store four megjoules of energy, which is then used to drive a motor attached to the rear axle. as power moves through the system it is fed back into the batteries, “creating an efficient compounding loop.”

 

efficiency was the keyword for the engine design, which allowed its cars to carry less fuel but get higher performance, and mercedes has even more planned for the coming year to hold off challengers such as ferrari.
