Aston Martin sues Henrik Fisker over Thunderbolt design

Imitation is supposedly the sincerest form of flattery, but Aston Martin isn't blushing after taking a look at the Fisker Thunderbolt. The british luxury brand has filed a lawsuit against the designer for allegedly copying the company's designs without permission in a US District Court in California.

Fisker unveiled the Thunderbolt at the at the 2015 Amelia Island Concours d'Elegance as his own take on the Vanquish. The former Aston Martin stylist's changes included reshaping the grille, adding a power dome to the hood and incorporating wraparound rear glass. The version on display was a concept for the design, but the plan was to sell a slightly modified production version through Galpin Aston Martin. This lawsuit puts assembly in doubt.

"This lawsuit centres on Henrik Fisker's creation and promotion of automobiles that Aston Martin contends infringes Aston Martin's rights, by an improper and unauthorised attempt to exploit and free-ride off them," said a portion of a prepared statement from the company emailed to Autoblog (embedded in full below).

According to Bloomberg, the automaker claims in the suit that portions of the design, including "the famous Aston Martin mark, wings logo, side vent mark, and Vanquish mark" are being coping in Fisker's design. The business also calls the plan to change the design for the production version a "bait-and-switch."

Fisker helped to shape the look of the Aston Martin DB9 and V8 Vantage during his time as a designer at the brand.
