2013 BMW 750i

See, the 2013 BMW 750i. The German automaker's flagship sedan bowed to North American audiences for the first time in Pebble Beach, and while the Big 7 designers were largely unchanged externally, pleased by the customer to many incremental improvements in the interior. Under the hood, engineers receive an additional 45 horsepower and 30 pound-feet of torque from the 4.4-liter V8 in the 750i with the addition of Valvetronic rustled. The swap pushes the machine, the final figures of power to 445 hp and 480 lb-ft of twist, the massive four-door help scoot to 60 mph in just 4.7 seconds. Hi-ho, Silver.

Even with the surge in power, says BMW has managed to improve the efficiency by about 25 percent due to the addition of a new eight-speed automatic transmission. Meanwhile, the 740i comes with the same performance for the year 2013, but given a 20 percent increase in efficiency thanks to the eight-speed transmission. Look for a new ECO-PRO powertrain management system for bending on both the 740i and 750i also. The system helps eek every last bit of available efficiency of engine and transmission and has a coast mode makes the 7-series is possible, free running at speeds between 30 and 100 miles per hour.
