The Rapide E and Lagonda Concept have been on show at the company's flagship showroom.

Aston Martin has been showcasing its electrified future in London, with two of its future models on display.

The Rapide E, Aston Martin's first all-electric production car; and the Lagonda Vision concept which showcases the reborn brand and its future all-electric products have been on show this week at Aston Martin's central London showroom in Mayfair.

The £250,000 Rapide E is Aston Martin's first all-electric production vehicle, and only 155 will be built.

The Rapide E's twin-motor drive system sends around 602 bhp to the rear wheel, propelling it to 60 mph in under four seconds and onto a limited top speed of 155 mph. It will be produced at Aston Martin's new St. Athan plant in Wales, which is also handling the assembly of the brand's first SUV, the DBX.

"Rapide E is proof of Aston Martin’s commitment to its Second Century Plan. Having an electric powertrain is no longer just a vision for our company, it’s reality," said John Caress, Vehicle Line Director for Rapide E at Aston Martin Lagonda. "We are producing fully-electric vehicles which will form part of our future strategy that will culminate when the first Lagonda vehicle enters the market.

“We have worked hard to ensure the high-performance standards of our customers are met. To achieve this Rapide E has a range of just over 200 miles on the Worldwide Harmonised Light Vehicle Test Procedure (WLTP) and a 0 to 80 percent charge which can be achieved in under 35 minutes using a 800V DC 100kW charging station.”

The Rapide E will make its UK dynamic debut at next month's Goodwood Festival of Speed.

Lagonda Vision Concept in London

Meanwhile, the Lagonda Vision Concept previews what we can expect from the Lagonda brand going forward. The nameplate was revived by Aston Martin a few years ago as an ultra-exclusive, all-electric luxury brand. The concept is essentially an SUV, much like the brands upcoming new production model.

"When we relaunched Lagonda, we set ourselves an ambitious target to be the world’s first luxury electric brand. We see the Lagonda brand sitting within a unique niche in the market," said Marek Reichman, Chief Creative Officer at Aston Martin Lagonda. "It is for the high-end luxury customer who wants to explore and be autonomous while remaining mindful of the impact they are having on the environment."

"Lagonda will achieve this but it will also provide joy and delight to the people who get to enjoy its unique internal environment."
