BMW launches the 220d and 225i Active Tourer models with xDrive technology. Compared to previous models, this is the first time BMW xDrive is made available on a front-wheel drive concept with transversally installed engines. The new xDrive aims to improve traction and cornering dynamics for BMW’s front-wheel drive vehicle, a highly controversial model that many  BMW enthusiasts have yet to embrace. The North American market has decided for now to not import the 2 Series Active Tourer.

BMW 2 Series Active Tourer-xdrive-11

The BMW 225i xDrive Active Tourer has a fuel consumption combined of 6,5–6,4 l/100 km, CO2 emissions combined 152-148 g/kg while the BMW 220d xDrive Active Tourer reports a fuel consumption combined of 4,8-4,6 l/100km and CO2 emissions combined 127-122 g/km. Both models feature BMW xDrive as standard in combination with the 8-speed Steptronic transmission.

  Slender, lightweight four-wheel architecture. The slender architecture featuring compact, lightweight components and the resulting low amount of space required by the new four-wheel drive system are excellently suited to the concept of the BMW 2 Series Active Tourer. Thus the additional weight of the entire four-wheel drive technology is only around 61 kg. Furthermore, measures for reducing system-related losses and an energy-efficient operating strategy ensure extremely favourable fuel consumption and emission levels.

BMW 2 Series Active Tourer-xdrive-24

Power from the front drive to the rear axle is transferred by means of an angular gear (Power Take-Off) on the front differential and a two-part cardan shaft. The central component of the four-wheel drive system is an electro-hydraulically controlled multiple-disk clutch (Hang-On) inside the rear axle drive, which facilitates infinitely variable distribution of torque to the front and rear wheels. The corresponding commands are provided by an electronic control unit which, like the hydraulic pump, is located on the rear axle.

BMW 2 Series Active Tourer-xdrive-21

Power Take-Off: angular gear and two-part cardan shaft. The angular gear is mounted behind the engine on the automatic transmission and crankcase. The input shaft is a hollow shaft construction and directly connected to the front axle differential. In this way, part of the drive force is transferred from the differential basket to the cardan shaft via the hollow shaft, the crown wheel and the pinion shaft. The angular gear operates at a fixed gear ratio (1:1.74) and is permanently engaged, meaning that the cardan shaft always rotates when the vehicle is driven. Reversal of transmission takes place in the rear axle drive so that the front and rear axle drive shafts both rotate at exactly the same speed.

BMW 2 Series Active Tourer-xdrive-27

Hang-On: electro-hydraulically controlled multiple-disk clutch. The multiple-disk clutch located in the rear axle drive (Hang-On) directs a proportion of torque to the rear wheels according to each driving situation, thus ensuring variable power distribution between the front and rear axle as required. In extreme cases (e.g. the front wheels are standing on ice), the ratio can be 0:100. The required operating pressure (0 to 40 bar) is delivered by an electro-hydraulic pump, the speed of which is defined by a pulse-width-modulated signal from the electronic control unit. Pressure is not measured by a sensor, but extremely accurately by means of voltage and power alignment. In order to ensure maximum positioning accuracy, run-in behaviour and temperature influences are independently compensated, the system constantly adapting to ever changing operating conditions.

BMW 2 Series Active Tourer-xdrive-14

Efficient valve helps reduce fuel consumption. Moreover, xDrive utilises an energy-efficient operating strategy: When four-wheel drive is not required – which is usually the case in day-to-day operation – the pump is deactivated, rendering the system unpressurised. The BMW 2 Series Active Tourer is then driven only via the front wheels. In order to make use of additional saving potentials, BMW has provided the multiple-disk clutch with a spring-loaded Efficient valve, which lowers the oil level in the clutch and significantly reduces friction losses (oil splash losses). When required, the system takes only fractions of a second to build up maximum operating pressure in the Efficient mode and thus deliver maximum torque to the rear wheels. This intervention goes unnoticed by the driver and passengers and without any losses in traction.

BMW 2 Series Active Tourer-xdrive-23

Intelligent networking: fast, precise and proactive. In order to guarantee efficient and constant power distribution to the front and rear axle as required, the four-wheel drive system is managed from the control unit of the Dynamic Stability Control feature (DSC). In order to analyse each driving situation, DSC analyses a large amount of data providing information on each respective running condition and ensuring optimum distribution of drive torque. This information includes vehicle speed, lateral and longitudinal acceleration, steering angle, wheel speed, longitudinal inclination, accelerator position and the setup via Driving Experience Control. Furthermore, the DSC status, including Dynamic Traction Control (DTC), Electronic Differential Lock Control (EDLC) and Performance Control is taken into account. Adjustment of the four-wheel drive system to the ever changing driving and road conditions is performed – in typical BMW xDrive manner – within fractions of a second, thus guaranteeing consistently neutral and safe handling even in difficult conditions. Nevertheless, the variable distribution of power between the two axles goes virtually unnoticed by the driver. Also, within the framework of the efficient operating strategy, torque distribution is precisely regulated as to avoid any loss of power due to wheel spin.

BMW 2 Series Active Tourer-xdrive-12

BMW xDrive: maximum traction, enhanced cornering dynamics. Thanks to DSC networking, any imminent wheel slip for example can be detected at an early stage. Through precise distribution of drive torque this situation can be anticipated and avoided. If for instance the vehicle threatens to drift outwards over the front wheels, increased tractive force is supplied to the rear axle, allowing the vehicle to turn in more accurately. On the other hand, xDrive directs excess force to the front wheels, should the rear of the vehicle threaten to swerve outwards. As a result, maximum four-wheel performance is available even before slippage occurs. Therefore, xDrive featured in the BMW 2 Series Active Tourer not only ensures best possible traction and safety in adverse road conditions, but also enhances vehicle stability, cornering dynamics and ride comfort. In driving situations where the interconnection of all four wheels is disadvantageous – i.e. in an emergency stop – the system opens the multiple-disk clutch completely within milliseconds.

BMW 2 Series Active Tourer-xdrive-01

Only if optimum power distribution to the front and rear axle is not sufficient to keep the Active Tourer on the desired course, DSC intervenes by reducing engine output and/or by decelerating individual wheels. Moreover, DSC assumes the function of a transverse differential lock: If a wheel spins without transferring power, it is automatically slowed down, whereby the axle differential directs more power to the wheel opposite.

The BMW 428i xDrive Gran Coupe was designed to evoke athletic elegance and sportiness in a single package. By some, it’s considered of the best looking BMWs in the current lineup and a viable option to those looking for a coupe vehicle with increased space and comfort. And when paired with xDrive, BMW’s intelligent all-wheel drive system, it handles every road and weather condition without sacrificing performance. One could say a perfect vehicle for winter weather and snow conditions as well. Powered by a 2.0-liter BMW TwinPower Turbo inline 4-cylinder, the 428i xDrive delivers 240-hp from a highly optimized engine featuring the twin-scroll turbocharger joined with variable valve control (Double-VANOS and Valvetronic) and high-precision direct injection. This gives the four-door coupe the power it needs for accelerating from 0-60mph in 5.7 seconds with its automatic transmission.

2014 has been rough for the MINI brand sales. Overall, the global MINI sales are down 5.3 percent, despite a strong October month. In order to revive the brand and become more focused with their products, Bloomberg says MINI will reduce the lineup to five models, down from eight. The British brand plans to focus on the three-door and five-door version of its classic hatchback, as well as on the Countryman crossover and Clubman wagon. According to MINI chief, Peter Schwarzenbauer, the fifth is likely to be electric (our bet goes on a version of the Superleggera Concept).

P90065804

“Like a superhero, each of these cars has its own personality and unique capabilities,” Bloomberg quotes Schwarzenbauer as saying in a speech prepared for an event near BMW’s Munich headquarters. “It is important to find the right balance between growth, on the one hand, and profitability, on the other.” Schwarzenbauer says that niche models are not only too expensive to produce given their small sales, but they also take up a lot of the marketing budget. Even though not confirmed yet, the models at risk to be eliminated are the Paceman, Roadster and Coupe. The article MINI trims down its lineup appeared first on BMW BLOG

Happy Thanksgiving everyone! While you chow down your turkey, we have the latest F30 and F31 LCI facelift prototypes to show you. Until now, adaptive LED headlights have only been available on the 4 Series, but as we can see, it will soon be available on the F30/F31 LCI models. Alongside the LED headlights, the F30/F31 LCI will also feature LED tail lights. As seen before, these prototypes show a restyled front bumper, deeper inset headlights (from the beefier bumper design) and shapelier kidney grilles. The M Sport bumper seen for the first time here doesn’t appear to undergo much changes. According to our latest info, the 335i becomes the 340i with the LCI refresh and its N55 engine will be replaced by the B58 engine. The 328i becomes the 330i and its N20 engine will be replaced by the B48 engine. The 3 Series LCI models begin production next July (2015).

AutoExpress UK brings two BMW supercars together on the track – the new i8 and the classic M1. The M1 came to life in 1978 at the Paris Motor Show as the M divisions first ever creation.The M1 coupe was hand-built between 1978 and 1981 as a homologation special for sports car racing. The body was designed by Giugiaro, taking inspiration from the 1972 BMW Turbo show car. At the time of its launch, it was one of the fastest and most dynamic cars on the market. It featured a 277 horsepower 3.5-liter straight-six engine and could reach speeds in excess of 160 mph. The redline came at 7,000 rpm and the M1 was capable of accelerating from 0-62 mph in 5.6 seconds.

BMW equips a 5 Series GT with the eDrive and TwinPower Turbo technology to showcase the future of plug-in hybrids. The ongoing development and refinement of hybrid drive systems under the Efficient Dynamics program is geared in particular to maximizing the amount of time the vehicle spends in electric mode. Therefore, BMW is developing a new generation of “highly electrified” hybrid concept models. First one made its debut today, the 3 Series eDrive Concept which will go on sale in 2016. Next year, the BMW X5 eDrive will also make its market debut.

bmw-power-edrive-prototype-17

Future models using the Power eDrive technology will include significantly higher-powered electric motors and batteries with twice the capacity of present versions. The Power eDrive electric drive system will contribute approximately two thirds of the vehicle’s combined output. The new BMW engines family with TwinPower tech will fill in the other third.

bmw-3-series-plug-in-hybrid-drivetrain-10

The drive components used in these future hybrid systems will offer combined outputs in excess of 500 kW, while the capacity of the lithium-ion batteries – up to 20 kilowatt hours – will likewise be greatly in excess of current hybrid systems. The increased all-electric driving range will reach up to 100 km (62 miles), essentially the new plug-in hybrids could run in the electric mode every day.

bmw-power-edrive-prototype-12

The combustion engine will fulfill several roles, such as providing a power boost when needed, extending the driving range and provide some recharging capabilities. On future plug-in hybrid concepts the electric motor, which will be the main source of power for everyday driving, will continue to drive the rear wheels, while the addition of a second electric motor driving the front wheels will create an all-electric road-coupled all-wheel-drive system. At the same time, an internal combustion engine will also supply power to the front axle.
