Japanese automaker Nissan is showing off a working prototype version of its arrow-shaped BladeGlider concept in Rio de Janiero this week, and hinting that enthusiasts should look forward to a similar electric sports car from the company in the future.

The vehicles, first unveiled as concepts at the 2013 Tokyo Auto Show, are battery-driven full electrics, with a driver seated centre-front; and two passengers behind them in the rear, Nissan says.

Top speed is about 190 km/h, and zero-to-100 km/h happens in under five seconds. The open-roof car also features massive dihedral-opening doors; and dashboard-mounted digital screens instead of traditional rearview mirrors.

Nissan’s built only two examples so far, but says the BladeGlider does indeed hint at production vehicles to come. “Nissan believes that enthusiasts should look forward to a zero-emission future and Nissan BladeGlider is a perfect demonstration of that,” said CEO Carlos Ghosn. “It’s the electric vehicle for car-lovers.”

Nissan will also be showing showing off another prototype in Brazil early August, a van it hails as the world’s first Solid Oxide Fuel-Cell (SOFC)-powered vehicle.

The e-NV200-based prototype, which Nissan calls an e-Bio Fuel-Cell, runs on ethanol or ethanol-blended water, but instead of burning it to drive the wheels like most ethanol-fueled vehicles do, it uses the fuel to drive a 24-kWh battery with a 600-km range.

The SOFC-powered vehicle will undergo further real-world testing in Brazil after its demonstration schedule has concluded there.
