B Drive or D Drive For Electric Cars: Which One Is The Best?

If you’ve ever driven an MG, you may have noticed that it has a disengaged MG. This happens when the MGs start to generate electricity and slow down the vehicle, which then translates into reduced fuel consumption. In other words, the MG disengages in B drive mode. This is a particularly useful feature if you’re descending long, steep hills, and you’re looking for a bit of extra torque to help you go up and over the hills.

B Drive or D drive For Electric Cars Comparison

“B” gives more regen when you let off the accelerator. This is useful for city driving and downhill gliding, but “D” is better for constant speeds and gliding. In fact, “B” is closer to Eco mode than “D,” which can sacrifice acceleration. Fortunately, there is a good middle ground between the two. Here’s what you should look for.

B Drive Mode

In B drive mode, the MG engages again to regenerate energy, similar to engine braking. The ICE flywheel is locked to the MG and the ECM bleeds air out of the engine through the valves to slow the vehicle down. The traction battery is recharged at a faster rate than normal braking, so the MG can engage again in b drive mode.
