The massive popularity of SUVs means that tuners are taking them into performance realms that were once the domain of supercars. Brabus' extensive history tuning Mercedes-Benz G-Class SUVs gives the company a credible claim to being one of the founders of the super-SUV genre, now populated by the likes of Lamborghini, Bentley, and Rolls-Royce. The Brabus 700 Widestar is based on the all-new Mercedes-AMG G63 and improves on it in every way. Starting with the twin-turbo V8, Brabus ups power output to 700 horsepower versus the stock 585, dropping the 0-60 time to 4.3 seconds. Almost four inches are added to the track via Brabus' custom fenders, allowing for the fitment of a staggering number of wheel and tire combinations, including Brabus' bespoke Monoblock Platinum Edition 23-inch forged wheels. New front and rear fascias are added, and the interior can be customized to suit any taste, with options ranging from leather and Alcantara to wood and carbon fiber trim, making for one of the most impressive bespoke SUVs on the market.
