The 7 Series is not your regular luxury sedan with its huge dimensions and a long wheel base. Thus to maneuver this luxury sedan on the tarmac, one would really require an engine which is capable enough to achieve that without a sweat. BMW doesn’t disappoint on the performance front either by appointing an impressive diesel unit and an enthusiast centric petrol avatar as well. Its milder 3.0 litre diesel engine is capable enough to deliver 265 hp at 4000 rpm along with an impressive torque of 620 Nm available at as low as 1500 rpm. The diesel engine is quite smooth and there is a very marginal turbo lag which exists and can be witnessed only when sprinting from a halt. On the other hand, for pure performance enthusiasts BMW appoints a mammoth 4.4 litre V8 heart that packs 450 horses under the hood waiting to be unleashed at 5500 rpm coupled with a blistering torque of 650 Nm available at your disposal starting 1800 rpm. Both its Diesel and Petrol engines are mated to an advanced 8 speed Steptronic automatic transmission that offers butter smooth gear shifts. Thanks to BMWs easy to hold joystick at the central console you can easily select gears on the go or if you want to have some fun by taking gear shifts under your control you can use the paddle shifters as well mounted on the steering wheel. For different driving styles, with the use of driving mode selector knob at the central console you can opt between Eco Pro, Comfort, Comfort+, Sport, Sport+ and an adaptive setup as well. What this does is, it automatically tunes the suspension setup along with car dampers and other car dynamics to adjust to the driving mode selected. Once behind the steering wheel you don’t really feel that you are driving a bulky and big sedan all thanks to its sharp steering response and potent engines at your disposal.
