![]() Meanwhile, the fuel economies of different models can also be very different even when in the same vehicle class. A key factor in how far a vehicle can drive while consuming much less fuel is its battery only range, which often varies a lot within a vehicle class, as shown in Figure 1. It is important to remember these are average values across models within vehicle classes. Footnote3 For short trips (50 km or less), fuel efficiencies are much better than longer trips (200 km or greater) for all plug-in hybrids. After they drain their batteries, they drive combined city and highway driving as regular hybrids, using their ICEs and electricity stored in their batteries during regenerative braking for the rest of their trips. At distances of 200 km driven, plug-in hybrids have fuel efficiencies much lower than electric vehicles and close to those of hybrid vehicles.įigure 2 below shows estimated, average fuel efficiencies for plug-in hybrids in litres equivalent per 100 km (Le/km), assuming vehicles drive combined city and highway driving Footnote2 as battery only until they drain their batteries. ![]() At distances of 50 km driven, plug-in hybrid vehicles and electric vehicles have much higher fuel efficiencies than hybrid vehicles. Plug-In-Hybrid Efficiency Varies with Distanceĭescription: This graphic compares the fuel efficiencies of electric vehicles, hybrid vehicles, and plug-in hybrid vehicles. If the plug-in hybrid needs to use its ICE a lot (for example, because it typically drives trips much longer than its battery only range) its fuel efficiency worsens. This means the fuel efficiency of plug-in hybrids can change quite a bit: if a plug-in hybrid can drive only on battery power most of the time, it can have very good fuel efficiency. However, the battery only ranges of plug-in hybrids are much shorter than the ranges of electric vehicles. This also means plug-in hybrids can have much better fuel economy than conventional vehicles and regular hybrids. This is because electric motors are far more energy efficient than ICEs. ![]() ![]() Some plug-in hybrids can drive for almost 100 kilometres (km) using their electric motors before their ICEs need to turn on.Ī prior snapshot showed how electric vehicles have much better fuel economy than vehicles with internal-combustion engines (conventional vehicles) and even regular hybrids. The difference between plug-in hybrids and regular hybrids is that the batteries in plug-in hybrids are much larger and can also be charged by plugging the vehicle into electrical outlets, similar to electric vehicles. Both plug-in hybrids and regular hybrids recharge their batteries while the car is driving, using regenerative braking Footnote1 and power generated by the ICE. Plug-in hybrid-electric vehicles (plug-in hybrids) are like regular hybrid-electric vehicles (regular hybrids): they have an internal-combustion engine (ICE) and one or more electric motors powered by a battery.
