You may mock this particular "upgrade" (and probably rightly so)
But be aware of this . . . . . .
From Racecar Engineering magazine :
2014: New regulations.
Although the current generation of F1 cars has already embraced hybrid technology with KERS (Kinetic Energy Recovery System), the sport is poised for a technological revolution in 2014 which will push environmentally relevant technology right to the fore.
The entire thrust of the sport in 2014 will be to deliver cars that are capable of racing at today’s speeds whilst using around 40% less fuel than we currently consume. Furthermore, built into the regulatory roadmap is a fuel consumption descalator that will require the teams to deliver competitive racing with less fuel each year thereafter. Of course, it is impossible to deliver on these challenging targets without technological change. The teams and the governing body of the sport (the FIA) have jointly constructed a fresh set of regulations that allow the teams to invest in many new technologies that will be of substantial use to the wider road car industry. The new regulations will see the capacity of the engines slashed from 2.4litres to just 1.6litres. At the same time, acceleration performance will be maintained by permitting a much larger hybrid system into the cars -more than doubled in its authority compared to the current cars. In addition to capturing the kinetic energy available during braking (this is the traditional way that a hybrid works), the cars will also be allowed to capture the heat energy that is currently wasted in the engine exhaust. There is nothing especially new about this; exhaust heat recovery has been performed by turbochargers in many applications for around 100 years. However, there is a twist on the exhaust heat recovery rules for 2014 that allow a novel and properly useful technology to be developed. The new rules permit the turbocharger system to be linked to an electric motor/generator unit. Why is this useful? Turbochargers have always offered efficiency gains, but these gains come with a price. Because it takes a certain amount of time to spin up to full speed when it is needed, the turbocharger does not deliver the instant power that is required when a driver puts his foot down. Lots of different tricks have been used over the years to try to reduce the so called “turbo lag” that prevents a turbocharged engine from delivering rapid power changes. The 2014 rules propose to solve this problem by linking the turbo to an electric motor/generator. With this solution, the electric motor can rapidly spin up the turbo when instant power is required. Similarly, when the turbo has more energy than it needs (at the end of a straight say), then it can be used to drive the linked generator unit, allowing electrical energy to be generated and stored in a battery when it can be used later on. Although proposed many times at a theoretical level, this elegant engineering solution has never been pursued in a real application. It is a difficult challenge, and it is exactly the sort of technological problem that Formula 1 is brilliant at solving. In two years’ time, our sport will be running the first working e-turbo units in racing conditions. It is widely expected that once the technology is mastered it will be an ideal candidate to allow future road cars to continue to move down the fuel efficient path of downsizing the internal combustion engines while scaling up the turbocharger. The regulations for the 2014 power unit are bulging with similar, highly relevant technologies. It is the first time that the sport has chosen a pathway that is consciously aligned with the development roadmap for the road car industry and these regulations provide a blueprint for how to embed social relevance into the DNA of the sport.

Now that sounds very interesting - will be wait and see game on how technology allows this to develop as viable and applicable addition to increase the efficiency of the engine.

This was discussed at length some years ago.
