NCE will Design & Engineer your BMW X6 to Power top convertible, NCE EDITION.

The BMW X6 is a mid-size luxury crossover released for sale in the second quarter of 2008 for the 2009 model year by German automaker BMW. The X6 was marketed as a Sports Activity Coupé (SAC) by BMW. It combines the attributes of an SUV (high ground clearance, all wheel drive and all-weather ability, large wheels and tires) with the stance of a coupé (bold styling, dramatic sloping roof).
The concept model debuted at the 2007 Frankfurt Auto Show and the production X6 officially debuted at the 2008 North American International Auto Show in Detroit and Montreal International Auto Show. While slightly longer and wider than the X5, it is significantly lower and seated initially only four, and since 2011, optionally five.
It is built in BMW’s North American plant in Greer, South Carolina alongside the BMW X5, whose platform it shares. It is dubbed a “Sports Activity Coupé (SAC)” by BMW. A hybrid version, the BMW Concept X6 ActiveHybrid, which will be the first such vehicle from BMW, was also announced. Later, in April 2009, the sporty X6 M version was announced, with a 555 hp (414 kW) 4.4-liter turbocharged V8.

Model range
Petrol engines
The first BMW X6 models were released for the North American market in two variants, both powered by twin-turbocharged gasoline engines.
The base model is the X6 xDrive35i which is powered by the 225 kW version of the N54 3.0-litre twin-turbocharged inline-six gasoline engine. The top-of-the-line model is the xDrive50i which uses the N63 V8 engine, producing 300 kW.

Diesel engines
Two diesel variants have been announced, and are expected to constitute as much as 90% of sales volume in European markets. The models are called the xDrive30d and xDrive 35d, respectively. They are powered by BMW’s 3.0-litre turbodiesel engine (in its sequential twin-turbocharged variant for the xDrive35d), and produce 235 PS (173 kW) in the xDrive30d and 286 PS (210 kW) in the xDrive 35d version. The second of these power units will form the basis of BMW’s Diesel launch in all 50 states in late-2008.[5]

BMW X6 M (2009-)
The BMW X6 M and X5 M are the first vehicles from BMW M GmbH to have xDrive all-wheel-drive and automatic transmissions, and are also crossovers as opposed to passenger cars. The X6 M was unveiled at the 2009 New York Auto Show and first went on sale in the 2010 model year.

The high-performance M derivative features a twin scroll twin turbo version of the 4.4-liter V8 BMW N63 engine with the Cylinder-bank Comprehensive Manifold (CCM). The engine is rated 555 PS (408 kW; 547 hp) at 6000 rpm and 680 N·m (500 lb·ft) at 1500-5650 rpm.
Other features include 6-speed M Sports automatic transmission with aluminum pull-style paddles on steering wheel, M Dynamic Mode feature, 10 mm (0.4 in) lower Adaptive Drive suspension, 4-piston fixed calipers with 15.6″ rotor at front and single piston floating calipers with 15.2″ rotor at rear, 20-inch alloy wheels with 275/40R20 front and 315/35R20 run flat tires, special gills in the front fenders, 20-inch light-alloy wheels.[12]
The car can accelerate from zero to 60 mph (0–97 km/h) in 4.5 seconds and 0-62 mph (0-100 km/h) in 5 seconds.

The engine utilizes BMW’s M TwinPower and patented exhaust manifold technologies to increase thrust and pulling force, while preserving the most compact dimensions possible. Two low-mass twin-scroll turbochargers are positioned together with the catalytic converters in the V section between the two banks of cylinders. By reversing the flow of gases through the engine from traditional arrangements, the intake and exhaust ducts are shortened and widened. The result is that pressure losses on the exhaust side are minimized.
The goals were to virtually eliminate turbocharger lag while maximizing combustion efficiency and power output. The new M V8 engine with twin-scroll twin turbo technology uses a single exhaust manifold with tuned-length runners, incorporating both cylinder banks and connecting cylinders in carefully selected pairs. This configuration, patented by BMW M and known as Cylinder-bank Comprehensive Manifold (CCM), offers quick response, a linear build-up of engine power, and a broad, consistent torque curve by feeding each of the twin turbochargers with a “charge pulse” at approximately every 90 degrees of crankshaft rotation, rather than the more traditional “irregular schedule” of charging.
Coupled with special suspension specifically optimized for M that features Adaptive Drive and the newly developed M Servotronic power steering, the performance Sport Activity Vehicle promises very competent handling. Other high-tech features include launch control for maximum acceleration and a six speed M Sport automatic transmission optimized for performance. Drivers can manually select gears using either paddles or an electronic gear selector lever. Electronically controlled, variable power distribution to the front and rear axle prevents even the slightest tendency to over- or understeer right from the start, before DSC Dynamic Stability Control is even required to cut in. BMW is referring to the new 4.4-liter motor as its “M TwinPower Turbo” unit. The name reflects the fact that the motor features Twin Scroll Twin Turbo Technology and a common exhaust manifold encompassing both rows of cylinders. Although traction control is standard, the M Dynamic Mode (MDM) greatly optimises the aggressiveness of the system. The MDM setting allows the driver to enter a controlled drift and push the vehicle’s handling to the limit. There is also a DSC-Off Mode.

ActiveHybrid X6 (2009-)
BMW X6 ActiveHybrid
In late 2009, BMW introduced an X6 featuring a version of the Global Hybrid Cooperation hybrid power train, popularly known as the two-mode hybrid system.[14] This car was confirmed as being called the BMW ActiveHybrid X6, and it is the world’s most powerful hybrid vehicle; it is not sold in the UK. The production vehicle was unveiled alongside a 7 Series hybrid at the 2009 Frankfurt Motor Show. The ActiveHybrid X6 went on sale in December 2009 in the US market with a base price of US$89,765.
The drive system featured in the BMW ActiveHybrid X6 consists of a 300 kW (407 hp) V8 power unit with BMW TwinPower Turbo Technology and two electric engines developing 67 kW (91 hp) and, respectively, 63 kW (86 hp.) Maximum system output is 357 kW (485 hp), peak torque is 780 Newton-meters (575 lb-ft.)
BMW ActiveHybrid technology offers the driver three significant options: to drive under electric power alone, to use the power of the combustion engine, or to benefit from the combination of both drive modes for short periods of maximum acceleration, using the 485 maximum. Driving completely free of CO2 in the electric mode is possible up to a speed of 37 mph (60 km/h). The hybrid also employs stop-start technology and other energy saving measures to help improve efficiency. The core-vehicle is however very heavy and the petrol power unit limits the extent to which fuel consumption can be reduced in absolute terms. The Turbo-Diesel models in the X6 range use less fuel, for example.

Dynamic Performance Control
The X6 marks BMW’s first use of its new Dynamic Performance Control system, which works in unison with xDrive all-wheel drive, both being standard on the X6. DPC is a drivetrain and chassis control system that works to regulate traction and especially correct over- and understeer by actively spreading out drive forces across the rear axle. Torque is split not only between the front and rear wheels (xDrive) but also from side to side at the rear for improved agility and added stability (through the DPC rear axle).
The DPC differential features clutch packs on both output sides that are actuated by an electric motor. The clutch pack activates a planetary gearset which causes one wheel to be overdriven. A conventional control system will use the brakes to reduce the speed of the faster moving wheel (which is the one with less traction)and reduce engine power. This leads to increased brake wear and slower than optimal progress. The DPC system speeds up the slower moving wheel (the one with the most traction) in order to maintain stability when needed. For example; while turning, the outer wheel is overdriven to provide greater acceleration using the traction advantage through the dynamic loading of the outboard wheel in cornering. In an oversteer situation, the inner wheel is overdriven to regain traction balance.

The BMW X6 is a four-door luxury performance SUV. Powered by a range of six- and eight-cylinder engines, it ranges from capable to brutally powerful. Introduced in 2008, the X6 is a new take on the combination of coupe and SUV body styles. Primary competition for the X6 includes the Land Rover Range Rover Sport, Porsche Cayenne, and Infini FX range. Priced to start from $56,500-$67,200 for the…
