TUM Researcher Markus Lienkamp: Why E-Mobility in This Form Is Not the Solution

The renowned vehicle technology professor from the Technical University of Munich reprimands the industry in his new work and states: The way we are currently designing e-mobility, with large and heavy cars, will not be a gain for the environment. He advocates for radical downsizing and a good measure of resource conservation. And for honest accounting instead of window dressing.

Munich vehicle technology professor Markus Lienkamp has published a new book titled "Status Elektromobilität 2023: Why the Electric Car is Also Not the Solution," which criticizes the automotive industry's approach to transitioning to e-mobility. Although vehicles are increasingly electric, many e-SUVs are far too big, too heavy, oversized, and overpowered to significantly reduce environmental impact. In some cases, the opposite is true.

Originally, he had no intention of writing another book, the renowned vehicle technology scientist from TU Munich outlines in his preface, noting that much of it represents his personal assessment of the situation without claiming "absolute truth," but also serves as a prompt for debate about whether the current path is the right one. Decisions have been made in politics and business, with the electric car as a BEV currently seen as the best foreseeable solution.

Myths and Fears Have Already Been Debunked

So why should he, as with the previous work, address the same myths, misinformation, and fears, he asks rhetorically. Now we have the "environmentally friendly produced electric car, also often an SUV, which is produced and operated with renewable energy - and thus CO2-free. We just need enough of them and then it’s 'Mission accomplished…'," Lienkamp continues. But unfortunately, this is not the case.

"The way we are currently designing and using electric cars is not achieving the main goal, namely reducing environmental impact - I am deliberately not speaking about environmental protection," the vehicle technology professor criticizes.

In the work, the PhD and habilitated scientist undertakes a detailed assessment of "Automobility 2023." He initially examines the electric trend in the EU and especially in China. Generally, the electric car is not succeeding due to state incentives, but because it is simply cheaper in the medium and long term compared to combustion engines, Lienkamp asserts. However, he also notes a further increase in CO2 emissions in traffic as well as traffic congestion.

Seemingly Paradoxical: Despite More E-Cars, Total Emissions Are Rising

He specifically highlights the paradox of rising emissions despite the switch to BEVs. The EU has only stipulated that vehicles should not emit CO2 during operation. This has led to heavy and large models, whose overall energy balance is significantly tarnished by the high efforts in production and resource extraction. This mix results in a CO2 increase. Moreover, the EU has not limited the number of vehicles.

"If the OEM sells an additional BEV, they can also sell another ICEV. Customers might acquire an additional ICEV due to the range limitations of the BEV," outlines Lienkamp.

While energy consumption during production is considered in the EU's electricity emissions trading, imported energy, such as battery cells from Asia, is currently not factored in.

Company Car Regulations: A Flat Rate for Driving

Another problem Lienkamp sees is company and corporate cars: In Germany, nearly two-thirds of all new vehicles are sold to commercial customers, with only about one-third of new vehicles sold to private customers. However, company vehicles are often used extensively for private purposes. Due to tax regulations in Germany, the company car driver pays only a percentage of the purchase price plus a surcharge for commuting to work. The fuel costs are then covered by the employer, regardless of how much the company car user drives privately.

"This means a flat rate for company car drivers. According to employees' wishes, companies continue to buy large and thereby CO2-intensive vehicles, whether BEV or ICEV. These vehicles are often kept only for a few years and thus dominate the overall vehicle fleet. To truly relieve the environment, policymakers must first start with company and corporate cars and create enough incentives there to purchase smaller vehicles again," appeals the vehicle technology professor.

A Process That Continues to Move in the Wrong Direction

This process will take a long time because for years there has been massive - and he means this in a physical sense - armament. Naturally, a heavy vehicle is at an advantage in a crash purely in physical terms, which is why many buyers don't want to drive a small vehicle out of concern for life and limb. Additionally, large vehicles are naturally more spacious and comfortable.

"The goal must be to require fewer cars and for them to become smaller and lighter again," explains Lienkamp, detailing the "how" in his book.

Counterproductive: Traffic Burden Increases

Lienkamp also identifies another trend that is not environmentally friendly: The number of vehicles in Germany is continuously increasing. All these vehicles are also driven as intended, leading to more traffic and inevitably to traffic jams. Additionally, they require extra parking space in already cramped cities.

"Anyone who thinks that traffic will decrease due to seemingly beneficial inventions like home office is mistaken. People working from home take more private trips and overcompensate for the eliminated commutes to work," he states.

Lienkamp sees an emerging conflict between cities and the countryside: City dwellers don't like commuters because they clog the cities and contribute to noise and exhaust pollution. Commuters want to use their own cars for trips to the city for time reasons. And city dwellers would also like to have their own car to drive into nature on weekends, where they are not so welcome by rural residents when traffic volume is too high.

Fixation on CO2 in Operation Falls Short

In his conclusion, Lienkamp expresses the conviction that "only by striving for genuine sustainability can we improve mobility in all aspects." He sees the pure fixation on CO2 – and then only in operation – as falling short and calls for a holistic accounting over the lifecycle, with all aspects of sustainability.

"This includes all environmental impacts, an economic calculation that internalizes all external costs and considers them over the lifecycle," the professor appeals.

As a third aspect, mobility must be socially just and enable participation for the weaker (in whatever dimension). Measures for this in larger cities include the expansion of public transport and the integration of taxis into the public transport system. These should be shared to reduce costs. The private car must become superfluous through car sharing in small communities so that people would gladly do without it.

"Then the freed-up space can be better allocated and managed, and made available to weaker road users, such as cyclists and pedestrians, as separate infrastructure," Lienkamp continues to outline. 

In the countryside, in contrast to the city, the car tends to be the solution because it offers high flexibility and enables flexible and efficient transport with few people and light traffic. However, the vehicles must become electric, which, according to Lienkamp, is not a bigger problem in rural areas in terms of charging. Commuters must be enabled to do without using their own car through offers such as shared transport, park and ride, and carpooling. Only in this way can traffic jams be reduced.

However, the scientist demands pressure tools such as tolls, parking fees, limited entry budgets, or separate lanes for vehicles with multiple passengers, so that "more traffic jams for solo drivers" would discourage commuters from driving into the city individually during peak times. According to Lienkamp, offers must generally be expanded first and then "repressive measures" cautiously added.

First Expand Offers, then Cautious Push Measures

The TU scientist expressed hope that politicians would introduce a Europe-wide cap-and-trade system for CO2 with cushioning for financially weak people. This must be designed across sectors. Only in this way can CO2 emissions be reliably reduced. The market would ensure that the most effective and cost-efficient measures are implemented first, Lienkamp believes.

"We all need to recognize that everything we do must be done out of love for today's and future people. Be it the climate, the avoided traffic jam, or the enabled mobility for an elderly person, everything is done for us humans. In MCube, we have summarized this under the three dimensions of improving air, time, and space. Only in this way can we inspire and convince our fellow humans with our measures and ideas," concludes Lienkamp.
