Lotterer: Porsche's second-year LMP1 success tough to repeat in FE

Porsche won both the Le Mans 24 Hours and the WEC LMP1 title in 2015, its second year of competition with the 919 Hybrid, and remained unbeaten on both fronts until it pulled out of the category two years later.

Expectations are high for Porsche in 2021 after Lotterer scored two podiums in its rookie FE season last year, and its prospects for this season have been boosted further by the addition of former Mahindra Racing star Pascal Wehrlein.

But Lotterer feels it won't be so easy for Porsche to ascend the pecking order in 2021, citing the similarities in powertrain hardware across the pack. By contrast, LMP1 regulations allowed for differentiation between Porsche's lithium-ion battery, Audi's flywheel storage system and Toyota's supercapacitor design during the early years of their three-way rivalry.

"Formula E is a different story [to WEC] because there is much less difference in the hardware," Lotterer told Autosport.

"In the WEC, the different manufacturers had different concepts and this had quite a big influence on the performance.

"Here, it's just small differences [that matter] on the powertrain and the inverter, the software and car set-up. The less opportunity you have to make the difference with hardware, the more you have to go into details, and the more the details matter.

"That's where Formula E is so challenging, because every team is pushing so far into the details. And even though the gains are marginal, they can give you the edge.

"If we can tick off all the details that we have to catch up with against the other teams, then we can focus on really making them better than the others. So we'll have to see where we are."

Lotterer has completed three full seasons in Formula E - the first two with Techeetah prior to his move to the new Porsche FE team for 2019-20 - but is yet to register his first win in the series.

He led the majority of the 2019 Hong Kong race, but suffered a puncture on the penultimate lap after being hit by the Envision Virgin car of Sam Bird.

While eager to break his duck in 2021, having racked up five second-place finishes and two poles, Lotterer says he feels that a lack of FE victories so far doesn't reflect negatively on his performances in the all-electric series.

"I always look at my own performance and there have been some really good ones, even though they weren't wins," he said.

"I picked a challenging route as well by coming into a new team [and leaving DS Techeetah], and it takes a bit of patience in the first year. And I still had a couple of chances to score a win. It should have happened in Hong Kong [in 2019].

"I think what we achieved last year was pretty good, so we just need to go one step better this year."
