Road Test: 2011 BMW X1 xDrive28i

BMW X1 xDrive28i 2011_01X1 xDrive28i is the first BMW with the new four-cylinder, turbocharged petrol engine. The new engine has a displacement of 1997cc and with the help of BMW TwinPower Turbo technology, high precision injection, double-Vanos and Valvetronic, it delivers 245 horsepower. This kind of power is usually found from the BMW’s engines that have two more cylinders and a much larger displacement. In addition to the horsepower, turbocharging the petrol engine creates a nice mount of torque as well. Hefty 350 Newton metres of torque is available at very low revs at just 1250rpm. This torque at low revs makes the engine very enjoyable to drive, but bringing up the real performance of this engine, it needs more revs. All the 245 horsepower wakes up at 5000rpm and then this engine shows its other side. The new X1 xDrive28i can sprint from zero to hundred kilometres per hour in 6.5 seconds with this automatic transmission. With the six-speed manual gearbox the sprint time is even 0,4 seconds faster.

The six-speed manual gearbox is standard on the xDrive28i and this eight-speed automatic transmission is available as an option. The automatic gearbox offers quite nice performance and the extra gears drop the engine revs on the highway, which makes driving on a longer journey more enjoyable and more efficient too. Shift times are short and automatic changes almost unnoticed. When you press the throttle pedal a bit more, the automatic quickly drops one or more gears down to improve the acceleration. The automatic also offers the manual mode, if you want to change gears yourself. If you have chosen the optional sports leather steering wheel or the M leather steering wheel, which both come with shift paddles, you can operate the automatic transmission manually while keeping both hands on the steering wheel.

According to the BMW, the six-speed manual gearbox is more economic in the city, while the automatic offers better efficiency on the highway thanks to its extra gears. Both the manual and automatic have the same 7,9 litre average fuel consumption and CO2 emissions of 183 g/km. Comparing to the previous model, which had the three litre, six-cylinder, naturally aspirated engine and the six-speed automatic transmission, this new xDrive28i produces a bit less power, but can accelerate faster. Due to the smaller engine displacement, the consumption has dropped 1,5 litres and the CO2 emissions are 36 g/km smaller.

One more advantage of the new engine is its weight. The new four-cylinder with its all-aluminium crankcase is considerably lighter than the previous six-cylinder engine. The lighter weight helps the efficiency, but also reduces the front axle load, which improves agility. Eventhough the X1 has the looks of the SUV, it still is very sporty to drive. The suspension works great on the twistier road as well and there isn’t much body roll, eventhough the car has a bit higher ground clearance. This small SUV is made for the tarmac and with the low profile tyres you don’t feel like taking it to the gravel road. And with the new engine, it is very enjoyable, but also quite economical to drive.
