BMW has recently introduced a new M Performance exhaust system designed to be an accessory for the BMW M3 Coupe, Sedan and Convertible. This new exhaust system was created with the racetrack and the street in mind. In fact, it was made from an extremely heat-resistant and lightweight chrome-nickel alloy called Inconel.
This flow optimized exhaust system lessens exhaust backpressure and permits the M3’s 414hp V8 engine to deliver a more powerful sound. Because of Inconel’s unique qualities, engineers were able to reduce the thickness of the tubing from 1.5mm to 0.8mm. This shaved off about 40% of the weight, or about 20 lbs. when compared to the stock exhaust system. Inconel is very corrosion resistant and has been used at the highest level of Motorsports.
The M Performance Exhaust consists of perforated inner pipes and polished titanium tips, which are laser engraved with the M logo. The exhaust is believed to stand for the best in technology and sportiness, emphasizing the individual character of the BMW M3. The designers developed the exhaust using state-of-the art CAD and FEM technology guaranteeing optimum fit and OEM quality.
Installation of the new exhaust may be done at any Authorized BMW Center for $4,374 plus installation. M Performance parts are warranted for the New Vehicle Limited Warranty period when the installation takes place before the first delivery of a new vehicle.
However, if the M Performance parts installation happens after the first delivery, the accessory will be warranted for the balance of the New Vehicle Limited Warranty period or two years and unlimited mileage from the date of installation, whichever one is greater.
Efficiency is one reason why the BMW M3 is able to accomplish outstanding performance. It comes equipped with the high-revving 4.0-liter V8 engine that can deliver output of 309 kW (420 bhp). When this is combined with a unique propulsion, the M3 delivers a superior acceleration response. While it already has a number of interesting performance features, the 8-cylinder engine offers a high degree of efficiency considering that it was specifically developed for the M3.
By having the Auto Start Stop Function, it becomes possible to top the extra efficiency potential. It also allows the driver to prevent any idling phases especially when stopping or when the vehicle is in congested traffic. What this does is to turn off the engine once the vehicle is not moving and to prevent any unnecessary fuel consumption. Once the driver chooses to drive again, the engine is immediately reactivated.
This Auto Start Stop Function is available whether the vehicle’s engine is paired with the Drivelogic M dual clutch transmission or the 6-speed manual transmission. Because of this, the M3, aside from the BMW ActiveHybrid X6 and ActiveHybrid 7, is one of the first models to utilize this efficiency-enhancing feature paired with the automated manual transmission.
The improved efficiency offered by the Auto Start Stop Function, depending on the model and the type of transmission, results in an improvement of up to 8% or around 24 grams CO2 for every kilometer. Take for instance the BMW M3 Coupé. It is powered with the high-revving V8 engine with the 309 kW/420 bhp output.
When paired with the Drivelogic M dual-clutch 7-speed transmission, fuel consumption under EU test cycle is measured at 11.2 liters for every 100 kilometers. When equipped with the 6-speed manual transmission, the M3 Coupé has fuel consumption at 12.4 liters per 100 kilometers.
The BMW M3 Sedan has the same numbers. However for the BMW M3 Convertible, average fuel consumption is 12.7 liters for the 6-speed manual transmission and 11.5 liters when equipped with the M dual clutch transmission that has Drivelogic.
The brand expects that all versions of the M3 will be able to meet any EU5 exhaust emission standards in the future. The rear lights have been modified and now have the glass covers in a homogeneous red colour, providing that extra visual highlight for the M3 Convertible and the M3 Coupé. There are also two illuminating light bank powered by LED units, resulting in a distinctive nocturnal design.
