Vorsteiner has introduced the GTS-V 1M Program for the BMW 1-Series M Coupe, giving it a front spoiler, rear diffuser, trunklid, exhaust and forged wheels. Autoclave Pre-Preg Carbon Fiber, which is what comprises the front lip and trunklid, makes the vehicle much stronger and stiffer compared to the regular material due to its one-of-a-kind crafting process.
There is a carbon-composite rear diffuser at the back with integrated dual splitters that offer a balance for the lower portion of the rear bumper.
Vorsteiner improves the performance by installing rear-facing aerodynamic fins that boost downforce. Its output is higher by 15 hp and 5 lb-ft of torque via the sport exhaust system, which could be built from stainless steel or weight-saving titanium.
Vorsteiner said that the system bolts onto the factory points and the acoustics provide a deeper tone with minimal droning.
The package is completed by twin seven-spoke, lightweight, race-inspired wheels that use T6 aircraft aluminum. These keep the unsprung weight at a minimum while the factory tire-pressure monitors are used.
BMW’s new 1-Series M Coupe was developed for a large, square footprint and near-perfect balance. It is 71 inches wide, 4.8 inches wider than the 1988 M3. It is also 172.4 inches long, making it only 1.3 inches longer. It also weighs 1,495kg DIN and features a 104.7-inch wheelbase, which is three inches longer than that of its 1988 M3 predecessor. Moreover, its front and rear track widths are at 60.7 inches each, which are the same as the 1988 M3.
Meanwhile, when compared to BMW’s 2011 135i Coupe, the 1-Series M Coupe is 0.2 inches longer, 2.1 inches wider, and 0.5 inches taller. It also rides on the same 104.7-inch wheelbase. What’s more, it features a track that’s 2.8 inches wider in the front and 1.8 inches wider in the rear. It also weighs 35kg DIN less.
The new 1-Series M Coupe also boasts a high-strength steel unibody, complete with unique, widened fenders as well as rear quarter panels that house its substantially widened track. Moreover, it has a metal roof panel that saves around 35 lbs compared to the BMW 1-Series models that sport a moonroof.
In addition, the BMW 2011 1-Series M Coupe, which was constructed as one of the carmaker’s most performance-oriented vehicles recently, won’t be available with a moonroof. The “savings” in weight, at the vehicle’s tallest point, results to a significant drop in its center of gravity, in turn contributing to the vehicle’s improved driving dynamics. This also helps maximize the head room.
BMW M's engineers faced numerous challenges in order to provide sure-footed and responsive handling for this powerful, high-performance, and luxurious coupe, while also keeping its mass under control.
This resulted to an aluminum suspension that was originally conceived for BMW’s current-generation M3, then tuned specifically for the 1-Series M Coupe at BMW M's test center in Nϋrburgring Nordschleife. Of course, every design for BMW starts with arranging major elements or components to facilitate near-perfect front-and-rear weight balance.
