Plug-in hybrids (PHEV) are slowly, but surely, becoming more mainstream, at least in the West. Automakers have been putting out these electrically-assisted powertrains and pairing them to popular models. One of them is BMW, and they've just put out a PHEV version of the X1.

With that in mind, just about every model of the BMW range can be ordered with plug-in hybrid variant from the 3 Series, all the way up to the 7 Series, as well as the X3, X5, and X7. So what's special about the X1 xDrive25e?

Aside from having a long name, BMW is claiming that it can do up to 55.5 kilometers per liter. So for every 100 kilometers, it will only consume 1.8 liters of fuel. That's thanks in part to the 9.7 kWh battery and 70 kw electric motor.

What makes this feat even more impressive is the fact that it's still saddled with an all-wheel drive system. If you want to save even more fuel, you can put the crossover on pure electric mode and can rely on that for up to 57 kilometers. It stays in electric mode for up to 30 km/h, which should make it ideal in heavy traffic situations.

As for the oily bits, the plug-in X1 uses a turbocharged three-cylinder, 1.5-liter engine that's good for 125 PS and 220 Nm of torque. It's then paired to the aforementioned 70 kw electric motor, resulting in a total system output of 220 PS and 385 Nm of torque. Those figures help this green X1 get to 100 km/h in 7.0 seconds, along with a top speed of 192 km/h. Of course, you won't get that 55.5 kilometer per liter figure if you try to reach those numbers.

Any exterior differences between this and the other gas (or diesel) fed models? Surprsingly, there are none. The only indication that this is a plug-in hybrid model is the flap for the electric socket on the fender. You can even get it with the M Sport package.

With hybrids tricking in the Philippine market, it would be interesting if BMW Philippines will bring in this plug-in X1. With traffic getting heavier and gas prices rising at an alarming rate, plug-in hybrids might just become even more appealing for the local consumer.
