BMW has introduced the new BMW 2 Series Gran Tourer, a premium compact model. At 4,556 millimeters long, 1,800 mm wide and 1,608 mm high, the 2 Series Gran Tourer accommodates up to seven people while additionally offering a load compartment that extends from 645 to 1,905 liters in the five-seater and from 560 to 1,820 liters in the seven-seater variant.
Five three- and four-cylinder gasoline and diesel engines will be available from market launch of the new BMW 2 Series Gran Tourer, all featuring the latest BMW TwinPower Turbo technology. In addition to the four-cylinder liter gasoline engine in the BMW 220i Gran Tourer and the three-cylinder in the BMW 218i Gran Tourer, three diesel units round off the engine portfolio available at market launch. They include the four-cylinder diesel in the BMW 220d xDrive and BMW 218d Gran Tourer as well as the three-cylinder diesel in the BMW 216d Gran Tourer.

All engines comply with the EU6 exhaust standard. Power is sent to the front wheels via a six-speed manual gearbox; as an option, BMW offers a six-speed Steptronic transmission for the three-cylinder engines, while the four-cylinders can be equipped with an eight-speed Steptronic transmission (standard in the BMW 220d xDrive Gran Tourer). All transmissions feature the Auto Start Stop function, which improves fuel economy. The Steptronic version also offers an efficiency-boosting coasting function. As soon as the driver releases the accelerator at higher speeds, the engine is decoupled from the rest of the powertrain and continues in coasting mode for a further reduction in fuel consumption.
The new engine family is based on an all-aluminium core unit designed for ultra-low friction. The closed-deck crankcase is particularly rigid, while thermally joined cylinder liners with twin-wire, arc-sprayed coating reduce weight as well as friction. A balancer shaft or two counter-rotating balancer shafts in the three- and four-cylinder engines respectively ensure smooth running across the entire rev range.
The gasoline engines feature turbochargers integrated in the exhaust manifold and liquid cooling for the manifold as well as the aluminium turbine housing. The exhaust gases cover only a short distance to the turbocharging system, making for agile response, while the very short warm-up time reduces interior friction in the system and with it fuel consumption. The close-coupled location of the catalytic converter and the electrically controlled boost pressure control valve—or wastegate—also have a positive impact on the emissions of the gasoline engines.
The gasoline engines feature turbocharging, direct gasoline injection, Double-VANOS variable camshaft control and VALVETRONIC fully variable valve control. The technology package for the thermodynamically optimized diesel engines includes turbocharging, variable turbine geometry and common rail direct injection with a maximum pressure of 2,000 bar.
BMW 220i Gran Tourer. The four-cylinder gasoline engine, which is also applied in the Active Tourer, delivers combined fuel consumption of 6.4–6.2 l/100 km (36.8– 37.9 mpg US, with CO2 emissions of 149–144 g/km). The 2.0-liter in-line unit has its peak output of 141 kW/192 hp on tap from 5,000 rpm, while peak torque is available between 1,250 and 4,600 rpm. A sporty performance curve propels the BMW 220i Gran Tourer from 0 to 100 km/h (62 mph) in 7.7 seconds and on to a top speed of 223 km/h (138 mph).
BMW 218i Gran Tourer. The BMW 218i Gran Tourer (fuel consumption combined: 5.5–5.1 l/100 km (42.8–46.1 mpg US; CO2 emissions combined: 127–119 g/km) is driven by a compact and lightweight three-cylinder gasoline engine. Ensuring maximum running smoothness throughout the engine speed range are a balancer shaft and the combination—rare in this class—of a dual-mass flywheel and centrifugal pendulum absorber. The 1.5-liter three-cylinder unit develops 100 kW/136 hp from 4,400 rpm. Peak torque of 220 N·m (162 lb-ft) is already available from 1,250 rpm and can be increased to 230 N·m (169 lb-ft) for short periods by using the overboost function. The BMW 218i Gran Tourer with six-speed manual gearbox accelerates from from 0 to 100 km/h (62 mph) in 9.5 seconds. Top speed is 205 km/h (127 mph).
BMW 220d xDrive Gran Tourer. The top performer in the engine line-up comes in the shape of the 2.0-liter four-cylinder diesel powering the new BMW 220d xDrive Gran Tourer (fuel consumption combined: 5.1–4.9 l/100 km (46.1–48 mpg US; CO2 emissions combined: 133–128 g/km). With a peak output of 140 kW/190 hp at 4,000 rpm and a maximum torque of 400 N·m (295 lb-ft) at 1,750 rpm, this BMW Gran Tourer offers extremely dynamic propulsion. This diesel model, moreover, is the only vehicle in the premium compact segment with up to seven seats and comes with all-wheel drive as standard. BMW xDrive distributes power to all four wheels as required, thus optimising traction and driving stability in all road and weather conditions. This intelligent all-wheel-drive system also improves cornering dynamics for the BMW 220d xDrive Gran Tourer. The torquey diesel completes the 0 to 100 km/h (62 mph) dash in 7.6 seconds and effortlessly accelerates all the way to 218 km/h (135 mph).
BMW 218d Gran Tourer. The BMW 218d Gran Tourer (fuel consumption combined: 4.5–4.3 l/100 km (52.3–54.7 mpg US; CO2 emissions combined: 119–114 g/km) is likewise driven by a 2.0-liter four-cylinder diesel. The new BMW 218d Gran Tourer develops a maximum output of 110 kW/150 hp at 4,000 rpm and a maximum torque of 330 N·m (243 lb-ft) between 1,750 and 2,750 rpm, taking this Gran Tourer from standstill to 100 km/h (62 mph) in 9.3 seconds and on to a maximum speed of 205 km/h (127 mph).
BMW 216d Gran Tourer. The 1.5-liter three-cylinder diesel engine in the new BMW 216d Gran Tourer delivers combined cycle fuel consumption of 4.2–3.9 l/100 km (56–60.3 mpg US; CO2 emissions combined: 111–104 g/km). Featuring a balancer shaft, dual-mass flywheel and centrifugal pendulum absorber, the BMW 216d Gran Tourer diesel develops 85 kW/116 hp at 4,000 rpm and 270 N·m (199 lb-ft) of torque from as low as 1,750 rpm, taking it to a top speed of 192 km/h (119 mph) and from rest to 100 km/h (62 mph) in 11.1 seconds.
BMW will this year be adding further engines and an extra drive variant to the engine portfolio of the new BMW 2 Series Gran Tourer. The BMW 216i will be launched as the entry-level gasoline engine, while the BMW 220d will join the line-up as a front-wheel drive variant with manual or automatic transmission.
An electromechanical power steering system delivers precise steering and feedback. To maintain the familiar BMW steering characteristics in a front-wheel-drive model as well, the hardware and software have been tailored to the drive concept. The servo unit and steering gear form a single component so that the steering assistance acts directly on the single pinion.
Torque steer has been minimized due to precisely calculated elastokinematics and software calibration, while engine forces are counteracted by optimally designed engine and transmission mounts along with the engine pendulum mount.
A range of electronic control systems boost safety and dynamics. The DSC (Dynamic Stability Control) system includes ABS, DTC (Dynamic Traction Control), EDLC (Electronic Differential Lock Control) and Performance Control, as well as subfunctions adapted to the front-wheel-drive system—such as a torque interface—that optimize the interplay between engine and chassis.
The driving dynamics of the new BMW 2 Series Gran Tourer are supported by specially configured control systems. In DTC mode the intervention of the stability control is slightly delayed to allow the BMW 2 Series Gran Tourer the appropriate amount of wheel spin for maximum acceleration. In DSC Off mode, precisely controlled brake power is applied at the front wheels to simulate the effect of a mechanical differential lock (EDLC function) for a significant improvement in traction when accelerating out of bends. Performance Control also heightens the agility of the BMW 2 Series Gran Tourer. This system positively influences the vehicle’s self-steering properties by suppressing the typical front-wheel-drive understeer tendency even before a critical level of stability is reached. Standard specification also includes the Start-Off Assistant, Dry Braking function, Brake Standy and Fading Compensation, while extra-sporty acceleration can be achieved with the aid of the Launch Control that comes as standard in conjunction with the eight-speed Steptronic transmission.
The new BMW 2 Series Gran Tourer also offers the driver the option of sporty, comfortable or particularly economical overall vehicle settings based on the driving situation or personal preference. ECO PRO, SPORT and COMFORT modes are available via the Driving Experience Control switch in front of the center console.
Efficient Dynamics. In the new BMW 2 Series Gran Tourer the ancillary units and electric consumers form part of an intelligent energy management system. On-demand operation of the coolant pump, a map-controlled oil pump and Electric Power Steering that consumes energy only when required all contribute to reducing fuel consumption. ECO PRO mode, activated via the Driving Experience Control switch, enables an improvement in fuel economy of up to 20%, while the coasting function (Steptronic only) and ECO PRO Route (in conjunction with the navigation system) can save yet more fuel.
High-tensile and ultra-high-tensile multi-phase steels and components that are precisely tailored to their purpose (tailored blanks) lend the body a high degree of stiffness coupled with extremely low weight. Along with the use of composite materials, the application of aluminium—e.g., in bumper supports, steering shaft, brake guards and wheel swivel bearings—also keeps vehicle weight down.
The 2 Series Gran Tourer has a drag coefficient of cd = 0.28. The front and rear end and the largely smooth-surfaced underbody panelling have been aerodynamically optimized. The familiar BMW Air Curtain at the front apron creates a curtain of air in front of the wheel arches to reduce turbulence at the front wheels. The integration of the roof spoiler with the D-pillar trailing edges (aeroblades) optimizes rear-end air flow, while the trailing edges of the rear lights serve to reduce drag further. Finally, on-demand control of the air flaps behind the BMW kidney grille and in the lower cooling air intake also contribute. A further benefit of reducing drag is to diminish noise inside the car.
