Infiniti plans to showcase its plans for electrification via this battery-powered retro racer concept at the imminent Pebble Beach Concours d’Elegance in California. The Japanese premium brand has already gone on record to say it will launch the first of a range of full-electric cars by 2021, so this is basically a fantasy-based taster of what’s to come.

For now, the company has released these sketches of the Prototype 10 concept, which follows on from last year’s Prototype 9 concept (well, duh). Like its predecessor, the latest concept again draws inspiration from racecars from yesteryear – specifically the late-1950s.

Designed under the direction of Karim Habib, who styled both the 6 Series Gran Coupe and the last-generation 7 Series while working for BMW, the latest concept could provide some clues to Infiniti’s future design language, but it’s what the slinky bodywork conceals that’s of real interest.

Unlike the Prototype 9, which basically just pinched its powertrain from the Nissan LEAF, the latest concept is expected to be equipped with twin electric motors, so it should serve up scorching performance.

Infiniti is keeping mum on details, but we’d speculate the vents directly aft of the cockpit suggest the presence of a rear-mounted motor or battery pack.

The other key point is that although Infiniti is an overtly luxury-focused brand, models such as the recent Q60 Red Sport 400 indicate the marque also wants to break into the high-performance segment. So, this racy concept is essentially a statement of intent as Infiniti aims to make further inroads into this sector.

It’s vital for Infiniti to leverage its parent company Nissan’s expertise in pure-electric technology, especially as China and Europe are set to impose restrictions and/or bans (in city centres) on combustion-powered vehicles.
