Formula One goes hybrid
If you’re a Formula One fan, you’re probably aware of the debate going on about the new Kinetic Energy Recovery System, otherwise known as KERS. It’s supposed to hit the Formula One racetracks this year. However, so far, only the road-going Ferrari 599XX has been brave enough to go hybrid. But that’s according to rumors from the 2009 Geneva Motorshow. And as Formula One gets set to launch the system on track, there are those who worry of potential risks to drivers and pit crew members.
First, a peek at the KERS. It’s basically regenerative braking, described as capturing a car’s kinetic energy and storing it for later use. However, it’s not without disadvantages. It’s supposedly effective only at high speeds. In the event of failure, you still need your brake pads to stop you from crashing into an obstacle. It also applies only to your drive wheels, meaning it’s either your front wheels or rear wheels, unless of course, you have AWD. It’s kind of similar to engine-braking. You use the engine to slow your car down via the drive wheels. Clearly, AWD can better utilize such a system. Then there’s the storage problem. If the batteries are fully charged with captured energy, then you can’t use it to slow your car down. You’d still have to rely on the brake pads. As I’ve said, it’s a lot like downshifting. However, in performance driving, the capability of the system to handle extreme weight shifts may depend on the quality of the equipment you’re carrying. If it can’t capture kinetic energy quick enough, you might as well use the brake pads to save you from understeering out of a corner.
Now, on to the debates in Formula One. Ferrari is one of the first few teams to start testing the KERS. There are two types of KERS being tested by Formula One teams – the mechanical flywheel system and electrical battery system.
Apparently, Ferrari found the expenses of testing the latter type truly heavy and challenging. Considering the amount of kinetic energy Formula One cars possess, it takes considerable batteries to store all the energy. And that’s something which requires both space and weight – two things that are of short supply in a Formula One car.
BMW came into the scene by taunting Ferrari, saying the maker has no guts. Citing BMW motor sport director Mario Theissen, “that argument not only speaks of a lack of competitiveness but also a reluctance to play a role in the bigger picture.” Clearly, Ferrari was made to look from red to yellow-belly, especially when FIA president Max Mosley himself sided with BMW saying, “Could you imagine the great F1 engineers like Chapman or Duckworth saying ‘I can’t do that because it is too complicated’?”
Hurting from such rumors, Ferrari denied claims that it was working on the system with Peugeot’s 908 HY to solve problems they were facing on KERS.
Well, fortunately, Mosley decided to go with mechanical flywheel-based KERS to make things a lot safer for both drivers and pit crew members. At least in the event that the systems fails to slow you down, you can always rely on the good downshift to cut your kinetic energy. Mosley makes sense by saying that the current technology doesn’t allow for adequate battery equipment to store a Formula One car’s immense kinetic energy, not to mention there isn’t a system fast enough to handle the blazing electric loads.
At least the FIA president is showing some of his old school traits by picking the mechanical KERS setup and banning the testing on the battery type. Currently, the teams are still facing immense challenges in incorporating the system. You can’t just pack a ton of wires, generators and batteries on a lightweight Formula One car. It just isn’t right.
As for me and my old school self, I’d clearly say no to the KERS. It’s still gears and pads for me.
