The 2017 BMW 740e xDrive iPerformance is already in production and will arrive at U.S. dealerships in August starting at $89,100 plus $995 Destination and Handling. The new 2017 BMW 740e xDrive iPerformance is powered by a plug-in hybrid drive system using the precisely executed interplay of a four-cylinder gasoline engine with BMW TwinPower Turbo technology and an electrical machine integrated into the 8-speed Steptronic transmission to generate a system output of 322 hp. This iPerformance model features BMW’s intelligent all-wheel drive system to distributes the combined power of the combustion engine and electrical machine permanently and as required between the front and rear wheels.
The combustion engine – developing a maximum output of 255 hp – is the most powerful four-cylinder engine ever fitted in a series-produced BMW. Instantaneous power delivery and peak torque of 295 lb-ft – on tap between 1,550 rpm and 4,400 rpm, ensure dynamic performance at all times. The electric motor has a maximum output of 111 hp and, as is characteristic for electric drive systems, it serves up its peak torque of 184 lb-ft.
The electrical machine is fully integrated into the car’s 8-speed Steptronic transmission ensuring optimal operation of pure-electric driving, electric boost and recuperation of braking energy. This integration also means the transmission does not require a torque converter (enabling a reduction in weight), while the electrical machine takes over the function of the starter element.
BMW’s 740e xDrive iPerformance dashes from 0 to 60 mph in just 5.1 seconds. The top speed is electronically limited to 155 mph.
The high-voltage lithium-ion battery in the BMW 740e xDrive iPerformance stands out with its compact construction and has a gross capacity of 9.2 kWh (net capacity: 6.5 kWh). It consists of 96 cells arranged in six modules and has its own cooling system integrated into the climate control system for the interior. The battery can be charged to full capacity in under 7 hours from a residential 120V outlet.
