To test the BMW i3 REX 94Ah electric extended range

The BMW i3 94Ah REX is a very interesting electric car. 300 km of autonomy within the reach of anyone with this battery of 94Ah and if gasoline is used.

With the i3, BMW She gave birth to a revolutionary car, a whole ahead of its time that even today, four years after its launch, still captivates who not only drives it, but anyone who approaches him. And it gets even more when it delves into the technology harboring this particular body, originally thought to be a three-door coupe and that the script demands, ended those two rear as "false".

He technological vanguardismo at BMW i3 starts with the bodywork, from building so exclusive that to date there is no other large production electric resorting to carbon fiber. Against steel and even aluminum, it provides a rigidity which makes it unnecessary -Integrates a central pillar in the door and lightness, factor should not lose sight of an electric: the greater the mass it will be more consumption Y more batteries They will be needed to reach equally far with a lighter car.

BMW i3: extended range

At BMW i3 there are aluminum chassis, as in i8 -here that metal is also used for all that it is not the envelope and in that habitáculo- hybrid construction is the key to that, in addition to behavior-the i3 is as rigidity affects precision- this BMW be achieved light, even integrating their propulsion system a gasoline engine to provide additional autonomy.

BMW i3 electricAnd is that today BMW i3 family of the They comprise four versions that differ according to the battery capacity and whether or not a system is available, based on the small two-cylinder gasoline engine, which it is capable of producing -the only electricity energy with which the wheels move i3– when it ends contained batteries, so keep them at a level fairly smooth.

The battery more capable of lithium ion -similar to carrying the i3 when started venderse-, he has a higher energy density because of their technical optimization; so that, with the same size and with a relatively small increase -40 kilos weight, it is able to offer a greater intensity in the electric current: of 94Ah against 60 of its predecessor. There is the possibility of store 33 kW compared to the previous 22, although the amount of usable energy both versions will be less questions battery life: 27.2 and 18.8 kWh, respectively.

average consumption 0.6 l / 100 km

Get with this version of BMW i3 94Ah next autonomies to 450 km that accredits the brand, also making use of 9 liters of gasoline deposit should not be easy: we have not succeeded. Now, what we have found each other feasible, giving normal use, it has put us in about 350 km (With a filled tank and battery after another), distributed between 230 and 120 electricity obtained with gasoline.

This leaves clear that the Energy with which it is actually efficient he i3 It is with the refueled electricity, not produced by the onboard generator.

BMW i3: from 2.8 euros / 100 km

The 230 first kilometers out, according repostemos at home or let us go to a service station and with fast charging, also could be free if we go to a recharging point a mall, for example, where we come to the regalen- between 6.5 and 13.6 euros. If no hurry and we carry home empty-the full battery can go from almost 8 hours to 12, depending on the amperage of the plug is 10 or 16- we would be in about 2.8 euros / 100 km, taxes already included, what makes fools of any car with a combustion engine only.

For example, a load point IBIL, faster –loads 40 kWh– we would pay 5.9 euros / 100 km; still a bargain compared to 8.7 euros / 100 km it costs to go to electricity produced “on board” and that leaves clear the role of gasoline as backup power. Yes, without Plug in sight, it is a “life insurance” as there are gas stations close and not give us too lazy to go to them.

BMW i3At BMW i3 we can choose the twin engine is activated when required by the driver, always with the proviso that the batteries have gone down 75 percent -detenemos and consumption of energy from these accumulators for use later-or, what will happen more often start automatically, what will happen before they run out entirely. In this case, there will be no way to turn off the gasoline engine, which always rotates at a constant rate while not reload electricity into an outlet.

BMW i3: driving sensations

Like all electric, costs can vary depending on what we propose traffic density, the terrain, the kind of way we use or our haste, much more noticeable than in a car with a combustion engine manner. Still, it is unlikely it is that a BMW i3 REX 94Ah like this it is below the 250 km outreach, even though we tend to go very quickly and highways in which, incidentally, his autolimited speed is 153 km / h real.

I could go much faster because there motor for this: Power 170 hp which makes the i3 can compete with powerful saloons. Especially if you look at the “short” acceleration, which is where the power benefits from the instantaneous torque developed by the engine when we accelerate.

And the throttle also requires a few lines to talk about this car, because it is a pedal serving for all: Same speeds that, with a decreased pressure on him, let us move “sailing” or, if we raise the foot, what is produced is an effect curiously like having stepped to slow, with recovery of electricity included among 40 and 57 kWh for a moment. Instrumentation helps a lot to catch the point and make it easier than it might seem.
