McLaren Applied: The Future of Electric Vehicles

With the increasing popularity of electric vehicles (EVs) in the UK, many questions arise about their future development and how they can match the performance and character of internal combustion engine (ICE) cars. Steve Lambert, head of electrification at McLaren Applied, believes he has the answers. McLaren Applied is a technology company that specializes in applying racing expertise to various industries, including electric cars.

Lambert and his team have categorized the development of EVs into four key phases. The first phase saw the rise of pioneers like the Tesla Roadster and the Nissan Leaf, proving that practical electric road cars were possible. The second phase, which recently concluded, witnessed the emergence of EVs like the Jaguar I-Pace and the Mercedes-Benz EQC, as legislators demanded cleaner cars and public confidence in the technology increased.

Now, we are entering the third phase, which focuses on efficiency. Lambert explains that during the lockdown, there was a rapid integration of EVs on the road, leading to a serious discussion about improving their efficiency. In this phase, manufacturers will move from offering serviceable EVs based on outgoing combustion cars to embracing efficiency in all forms, including packaging, weight saving, battery development, aerodynamics, and powertrain refinement.

One of the key advancements in this phase is the adoption of an 800V electrical architecture and silicon-carbide inverters. Lambert considers the inverter as an unsung hero in an electric powertrain, as it determines how much energy the car needs, controls the motor, and improves power delivery. The combination of an 800V electrical architecture and silicon-carbide inverters will become a badge of performance, similar to GTI models today. An 800V inverter can significantly reduce efficiency losses, allowing for smaller batteries and motors, as well as a reduction in raw materials usage.

Looking ahead to the fourth phase, Lambert believes that precise motor control, facilitated by 800V silicon-carbide inverters, will create unique driving characteristics specific to each car’s brand and model. The Porsche Taycan is a prime example of this, as its Porsche-typical feel is attributed to its control over its electric motors. Lambert envisions more imaginative driving modes and personalized settings in future EV models.

The ultimate goal of these developments is to ensure that EVs can match the appeal of ICE cars. Lambert emphasizes that progressive technology doesn’t have to be boring, and based on conversations with car manufacturers, the next generation of EVs is likely to be better to drive than ever before. It is crucial for people to continue enjoying their driving experience while benefiting from the advantages of electric propulsion.

One significant contributor to early EV development was the adoption of the Kinetic Energy Recovery System (KERS) by Formula 1 cars in 2009, followed by the introduction of Formula E in 2014. KERS brought innovation and efficiency improvements that have benefited road cars. For example, Formula E teams transitioned from multi-speed to single-speed gearboxes, reducing complexity, weight, and cost. This transition has also been mirrored in road cars.

In conclusion, McLaren Applied’s theories about the future development of EVs provide valuable insights into how manufacturers can enhance their performance and character. With the ongoing advancements in efficiency and motor control, EVs are poised to match and even surpass ICE cars in terms of driving experience. The combination of an 800V electrical architecture and silicon-carbide inverters will become a hallmark of performance in future EVs. As the popularity of EVs continues to grow, it is exciting to anticipate the innovations that will shape the future of electric mobility.
