It seems the automotive world has a penchant for dramatic comebacks, and the latest revivalist is none other than the range-extender electric vehicle (EREV). Once seemingly relegated to the history books, this powertrain is now being championed by industry titans like Ford and Renault, signaling a significant shift in how we might approach electric mobility in Europe.
The Ghost of EREVs Past
Personally, I find it fascinating how technologies can fall out of favor only to be resurrected. The EREV, which essentially uses a small internal combustion engine as a generator to charge the battery and extend an electric vehicle's range, was once considered a promising middle ground. We saw early adopters like the Chevrolet Bolt and, most notably, BMW’s i3 experiment with this setup. However, BMW's decision to pivot away from the range-extender i3 in favor of a purely electric version seemed to be the nail in the coffin for many. The industry then collectively shifted its gaze towards fully electric vehicles (BEVs) and more conventional hybrids. What many people don't realize is that this abrupt abandonment left a void, a segment of consumers who might have benefited from the EREV's unique blend of electric driving and gasoline reassurance.
A New Dawn for Extended Range?
What makes this resurgence particularly interesting is that it's being driven by legacy automakers, not just the new wave of EV startups. Ford's European head, Jim Baumbick, is quite vocal about the potential, suggesting that EREVs could "bring about a fundamental change" in the European market. From my perspective, this isn't just about offering another powertrain option; it's a strategic acknowledgment that the all-electric dream might not be universally achievable or desirable for every consumer right now. Ford is planning a range of electrified vehicles, and the EREV is poised to play a "very significant role." This implies a recognition that the transition to full electrification is complex and might require more nuanced solutions.
Renault's Vision for Larger EVs
Renault's CEO, François Provost, echoes this sentiment, specifically highlighting the suitability of EREVs and plug-in hybrids for larger vehicles. His point about it being "insane to have 2.5 or 2.7-ton cars driving through city centers every day" is a sharp observation. He believes these larger vehicles could achieve impressive all-electric ranges of up to 124 miles (200 km) on EREVs. This suggests a pragmatic approach: why burden a massive vehicle with the full weight of a large battery when a smaller, more efficient generator can provide the necessary backup? It's a clever way to balance environmental aspirations with the practicalities of vehicle size and energy demands.
The Charging Conundrum
However, a significant hurdle remains, and it's one that plagued EREVs and plug-in hybrids from the start: user behavior. Research consistently shows that a substantial number of plug-in hybrid owners rarely, if ever, charge their vehicles. They essentially treat them as conventional gasoline cars, negating the primary benefit. Baumbick rightly points out that Europe "needs to do a better job promoting charging." This isn't just a technical issue; it's a behavioral and educational one. If people don't understand or aren't incentivized to charge their EREVs, the entire premise falls apart. In my opinion, automakers need to invest as much in user education and charging infrastructure support as they do in the technology itself.
A Potential Partnership and the Future
The prospect of Ford and Renault deepening their collaboration on EREVs is also a noteworthy development. If these two giants can align on core technology, it could accelerate development and bring more competitive EREV models to market faster. This collaboration hints at a broader trend: as the EV landscape matures, partnerships and shared platforms will become increasingly crucial for legacy automakers to compete effectively. What this really suggests is that the future of electric mobility might not be a monolithic all-electric highway, but rather a diverse ecosystem of powertrains, with the EREV carving out a vital niche for those who need that extra assurance on longer journeys or for larger vehicles. It's a pragmatic evolution, not a step backward, and I'm eager to see how this unfolds.
