Developed as an eco-friendly sports car that adapts to AC Schnitzer's new motto "Efficient Performance", the 99d gets its name from its CO2 emission levels and the diesel powerplant housed under its hood.
Having boosted, tuned and dressed up BMWs over the good part of 20 years, AC Schnitzer will present a gas (LNG) powered GP3.10 super 3-series coupe (E92). Equipped with a modified version of the BMW M5/M6�s 5.0L V10, the engine � which can also burn petrol - produces 552hp (+45hp vs standard M5/M6) and kicks out 540Nm of maximum torque. When it alternatively uses LNG (which is significantly cheaper than petrol) the V10 spews about 15% lesser CO2. Yet, imagine lining up with LNG-powered taxis in Malaysia - for the limited gas refuelling island(s) - at only certain fuel-filling stations!
Under the ventilated hood lies BMW�s award-winning V10 engine additionally equipped with sequential LPG system consisting of two parallel 5-cylinder vaporizers. Impressively, there's no loss of power and its delivery dynamics, with sprinting to 100 km/h in 4.5secs, and the 200km/h attained in just 13.9secs! It will spurt all the way to 320km/h if you�ve got the gall and mental strength. Racing suspension from Aachen sharpens stability and handling in view of the massive power and torque hike. Just as important, brakes are uprated too: 8-pot fixed calliper brakes with perforated vented discs of 374mm x 36mm up front, while the rear axle gets a 4-pot brake system with 350mm x 24mm rotors.
The rear styling with its bulbous-concave contours, the rear skirt with integral diffuser and the rear roof wing with carbon centre part are muscular and menacing. Just as aesthetically aggressive is the distinctive front skirt with coarse-mesh sports grille lining the massive air dam. Equally jaw-dropping is the racing rims Type VI, also by Aachen which combines the classic Y-spoke appearance with five striking hollow spokes, both items in different shades. 
For those privileged few that have taken deliveries of the new twin-turbo 335i coupe or even the lesser sibling 323i coupe, here are some after-market suggestions from famed BMW tuner, AC Schnitzer:
