The spacious interior provides innovative equipment features with maximum functionality and sitting for up to seven people. It set new standards in efficiency among its competitors. This 2010 E70 model LCI (life cycle pulse), includes several exterior enhancements. The two new engines introduced have additional Efficient Dynamics measures which deliver optimum power and torque with excellent fuel economy and emissions. Due in part to the introduction of the eight speed automatic transmission that provides precise shifting and a smooth driving experience and the standard equipment Brake Energy Regeneration. Available Engines As of April 2010, the E70 LCI is offered in following model variants: • BMW X5 xDrive35i N55B30M0 engine (225 kW/300hp and 400 Nm/300lb-ft) • BMW X5 xDrive50i N63B44O0 engine (300 kW/400hp and 600 Nm/450lb-ft) • BMW X5 xDrive35d US (Advanced Diesel with BluePerformance) M57D30T2 engine (200 kW/265hp and 580 Nm/425lb-ft) as previously. 3 E70 Life Cycle Impulse Body Dimensions Some dimensions have changed when compared to the previous E70.

The side air intakes have been enlarged for improved cooling and the front fenders have been modified to accommodate the new front facia. The black plastic trim at the bottom edge of the body is reduced to show more painted surface. The newly designed front of the E70 LCI is characterized by the following features: E70 LCI Front ® ® ® Index Explanation 1 New headlight design 2 Indented fog lamps 3 “Simulated” underbody protection (skid plate) 4 Front bumper with larger side air intakes and horizontal webbed grill 5 E70 Life Cycle Impulse Rear The reshaped rear bumper with more body color trim leads to the tailpipe surrounds. The taillights have been redesigned to an L-shape and now have LEDs for enhanced brightness. The fog lights have been moved inwards making the vehicle appear lower. The rear of the E70 LCI is characterized by the following features: E70 LCI Rear Index Explanation 1 Narrow white driving light elements 2 L-shaped taillights with horizontal lines 3 New exhaust tailpipes (diameter was increased from 70 mm to 80 mm) 4 “Simulated” underbody protection “skid plate” 5 New rear diffuser 6 E70 Life Cycle Impulse Sides The sides of the E70 LCI have been revised with the following details: • New, reshaped side wheel arches • Shorter front overhang • Redesigned rear bumper E70 LCI Side 7 E70 Life Cycle Impulse Interior Dashboard The elegant dashboard with the typical BMW driver orientation was enhanced by the high quality and harmony of the materials used. E70 LCI Dashboard Diver Assistance Systems The E70 LCI is available (from May 2010) with the following driver-assistance systems: • Side-view Camera • ACC Stop & Go • Lane departure warning 8 E70 Life Cycle Impulse Side-view Camera The two side view cameras are located in the left and right upper corner of the front of the bumper. They ensure an additional field of vision in poor visibility situations and allow early detection of traffic approaching from the sides when pulling out or entering roads. E70 LCI Side-view Camera Note: For detailed information on "Side-view Camera" see the new BMW 5 series “F10 Complete Vehicle" training material available on TIS and ICP. ACC Stop & Go Active Cruise Control regulates speed when the road ahead is clear and switches auto¬ matically to distance control when the sensor for ACC Stop & Go detects a slower mov¬ ing vehicle in the lane ahead. In this way Active Cruise Control not only assists the driver on little-used roads, but also in heavy traffic. Active Cruise Control takes over the routine of accelerating for the driver precisely adjusting the distance and speed with regard to other road users. The Stop & Go function of the Active Cruise Control can bring the vehicle to a complete stop if necessary. If the vehicle ahead begins to move again after having stopped, the driver is notified. To pull away again, the driver has to acknowledge the message. The pulling-away process is controlled fully automatically by ACC Stop & Go only if the dura¬ tion of the stop is very short. 9 E70 Life Cycle Impulse The sensor for the ACC Stop & Go is located behind the lower grill in the front bumper cover. ACC Sensor Location Index Explanation 1 ACC-Sensor The LCI E70 now can be ordered with Active Cruise Control w/Stop & Go. A new sensor is used for this function which is already known from the F10. Because E70 does not use an ICM, In this application the sensor is not connected to the integrated chassis management (ICM) control unit but rather to the longitudinal dynamics management (LDM) control unit as in the E6X LCI vehicles. The sensor for ACC Stop & Go is a radar-based sensor designed to detect the range of the vehicles traveling in our path. Both the short range and the long range radars are incorporated in one sensor. The sensor sends out focused electromagnetic waves with a transmission frequency of 76-77 GHz. The echoes reflected from objects are received and evaluated by the sen¬ sor. In this way, the sensor can gain information about the size, distance and the speed of the objects in front of it. Note: For a detailed description of the new ACC sensor and the operation of "ACC Stop & Go" system refer to the BMW 5 Series F10 training material available on TIS and ICP. 10 E70 Life Cycle Impulse The following graphic explains the inputs and outputs within the components of the E70 LCI ACC Stop & Go system on the E70 LCI.

The E70 LCI diesel (xDrive35d) however, will see no changes to its powertrain. The following table lists the most important specifications regarding the engines installed on the E70 LCI.

GA8HP Automatic Transmission The E70 LCI is standard eguipped with the new GA8HP eight speed automatic trans¬ mission on all gasoline models. Especially close gears ratios allow better use of the opti¬ mum speed ranges. This increases the driving dynamics and shifting comfort while enhancing fuel economy and emissions. The GA8HP45Z is installed with the N55B30M0 engine in the xDrive35i. The GA8HP70Z is installed with the N63B44O0 engine in the xDrive50i. Note: For more information regarding the GA8HP automatic transmission refer to the F07 and F10 training material available on TIS and ICP. 12 E70 Life Cycle Impulse Transmission Emergency Release There is a new operating concept used for releasing the transmission parking lock mechanism (transmission parking lock emergency release). The existing transmission emergency release is being gradually removed from all vehicles with the 8 speed auto¬ matic transmissions, beginning with the E70 LCI. In the event of a fault affecting the powertrain, the transmission parking lock can be unlocked mechanically and put in “Neutral” by means of a set screw/stop (adjusting screw) that acts on the gear selector lever. In addition to the mechanical transmission parking lock emergency release, the procedure to put the vehicle in “Neutral” can also be done electronically via ISTA.

The operation of both the mechanical and electrical parking lock emergency release may only be done by BMW service personnel. To actuate the mechanical transmission parking lock emergency release the vehicle must be lifted and the underbody paneling removed. This is necessary in the event the vehicle has to be put on a flatbed for transportation to the service department.
