Founded in 2009 by British musician Rob Dickinson, Singer Vehicle Design is a California-based customization and restoration shop that specializes in 964-era Porsche 911s. In the past, we’ve seen loads of lust-worthy cars from Singer, but this latest example bests them all. Commissioned by client Scott Blattner, the goal was a lightweight, high-performance revamp of Blattner’s 1990 911, but the end product goes above and beyond in just about every single way. For starters, Singer sourced input with some of the biggest names in Porsche performance, including motorsport engineer Norbert Singer, engine specialist Hans Mezger, and racing driver Marino Franchitti, not to mention automotive journalist and Top Gear host Chris Harris. Big-name companies like Michelin, Brembo, and BBS Motorsport also got in on the mix, while Williams Advanced Engineering (yep, the F1 folks) played a major role in the vehicle’s technical development. The project took two years to complete, but the results are staggering. Dubbed the Dynamics and Lightweighting Study, or DLS, every part of the 911 was tweaked, and Singer is so happy with it, the tuner is now offering special DLS services to select customers.
