The MCTC was officially opened by The Duke of Cambridge, Duchess of Cambridge, and the Crown Prince of Bahrain in November 2018. Products and strategy McLaren's first purpose-built road car was the F1, based on a concept developed by Gordon Murray that he convinced Ron Dennis to back. McLaren Cars went into hibernation following the completion of the F1's production run, and McLaren didn't return to the production car market until launching McLaren Automotive in 2010, just prior to the release of the MP4-12C (eventually simplified to just 12C) in 2011. McLaren launched its current three-tier product structure in 2015, dividing their range of cars into the Sports, Super, and Ultimate Series. Cars in the Sports and Super Series are given names based on the car's power output in PS, followed by a model designation (C for club, S for sport, GT for grand tourer and LT for longtail). The entry-level Sports Series consists of the 570S, 570S Spider, 570GT, 540C, 600LT and 600LT Spider. The Super Series, considered to be McLaren's core model range, originally included the 650S, 625C, and 675LT. These were replaced with the 720S in 2017 (and 720S Spider in 2018). The high-end Ultimate Series was led by the P1 and P1 GTR, now it includes the Senna, Senna GTR and the upcoming Speedtail, intended to be the successor to the original F1. The F1 and 12C were retroactively included in the Ultimate and Super Series, respectively. Models Bold text signifies a model is currently being produced. Collaborations Mercedes-Benz SLR McLaren In 1999, McLaren agreed to design and manufacture the SLR (also known as P7) in conjunction with Mercedes-Benz. DaimlerChrysler was the engine supplier to McLaren Racing through its Formula One partner Mercedes-Benz division. The final stages of production of the Mercedes-Benz SLR McLaren took place at a designated assembly facility at the McLaren Technology Centre.
