Having used taxi's daily at work and also in leisure time and driving a Hybrid car myself can anyone explain why the taxi drivers always seems to driver in "D" mode rather than the more fuel efficient and easier to drive "B" or break assist mode?
Toyota's also Mercedes and a number of other types of Hybrid.The first question needs to be exactly what make of car you are querying.
On my hybrid it will only drive in D and automatically regenerates but that setting can be increased if I so wish. Any regeneration level applies some "braking" force but the higher I set it, from 1 to 3, increases that force.
The shift lever offers four positions: R (Reverse), N (neutral), B (engine braking) and D (drive). For normal driving, D (drive) is absolutely fine, but should you need it, position B has the effect of engine-braking handy when descending a steep hill, for example. It’s not recommended to leave the car in position B for normal driving, mainly because you’d end up using more fuel than necessary!
