Power to the people: An Audi e-tron is recharged. The lack of charging infrastructure in South Africa makes owning a hybrid vehicle the best alternative to the internal combustion engine for now.
Back in the day, if you wanted to buy a vehicle, your choices were limited to petrol or diesel. Oh, how simple it was …
Over the years, a few electric cars trickled onto catalogues but now, in 2023, when carmakers are making grand claims surrounding zero emissions, the choices aren’t as straightforward.
The world has changed, with the mushrooming of hybrid, plug-in and fully electric vehicles as governments push towards a zero-emissions future. Global powers, such as Europe, the US and Australia, plan to ban internal combustion engine (ICE) vehicles by 2035.
While no cut-off date for ICE-powered vehicles has been set in South Africa yet, vehicle manufacturers have started rolling out electric cars, forcing drivers to gradually make a mobility mindshift towards electrified transport.
Right now, you can buy a hybrid, plug-in hybrid or fully electric vehicle in South Africa. While these are somewhat rare still, many do not know the differences between them.
We look at the three forms of electrification and which one is best suited for our market.
Hybrid
The history books tell us Ferdinand Porsche made the first hybrid car, known as the Lohner–Porsche Mixed Hybrid, in 1900. His prototypes were two-wheeled, battery-powered electric cars with two hub-mounted motors at the front axle.
As the technology was mastered, Porsche developed cars that used hub-mounted electric motors at each wheel, powered by batteries and a petrol-engine generator, to reduce emissions and improve efficiency.
All that happened about 110 years before the launch of the Cayenne S Hybrid in 2010.
Many marques have since mastered the technology as an alternative to the latter two forms of electrification. The truth of the matter, though, is that plenty of manufacturers are still playing catch-up and have only recently added hybrid models to their ranges.
But what is a hybrid car? Well, in a nutshell, a hybrid vehicle is equipped with a petrol or a diesel powerplant, paired with an electric motor.
Hybrids can drive with an electric motor, ICE engine or a combination of the two. The vehicle calculates and decides when the different powerplants take over — a transition that occurs seamlessly while moving.
Hybrid cars tend to use a relatively small battery pack, so their fully electric driving range is minimal.
Charging them is easy — the battery can be recharged on the move by the engine or the power generated when the car is coasting or braking.
The list of hybrid vehicles available in South Africa is large. An appropriate example, in this case, is the Toyota RAV4 Hybrid which packs a 2.5-litre 4-cylinder engine paired with two electric motors. The engine alone pumps out 131kW and 221Nm, while the electric motors supply 88kW and 202Nm. When the two systems work together, they produce about 163kW of usable power.
Regarding efficiency, the RAV4 Hybrid seems to be a winner, with our long-term vehicle figures hovering around the 6.4l/100km mark.
Plug-in hybrid
Think a hybrid vehicle with a bigger battery, a dedicated charging port as well as a combustion engine. It’s that simple. A plug-in hybrid electric vehicle (or PHEV) is, in some ways, similar to its hybrid counterpart, yet there seems to be a growing demand for PHEVs in South Africa, regardless of the charging infrastructure concerns.
A PHEV packs a bigger electric motor plus a larger battery that can be recharged using a conventional power socket or at a dedicated EV charging station.
Their ability to continue running, even when the battery is depleted, and their potential to save you lots of money has made them more attractive than fully electric cars.
Due to their bigger batteries, plug-in hybrids can travel longer distances on battery power than other hybrids before the engine takes over.
Their EV range is generally between 32km and 50km, however, some models, such as the Jaguar E-Pace and F-Pace PHEVs, claim a range of up to 66km.
An advantage of having a PHEV is you don’t need to worry about stopping at a charging station to recharge the battery because the conventional engine automatically kicks in and recharges it. No range anxiety here.
All electric
All-electric vehicles are all about simplicity. They do away with the ICE in exchange for electric motors that don’t emit harmful fumes. On paper, that translates to cheaper running costs in addition to being able to whizz past crowded filling stations.
They pack a larger battery than hybrids that powers one or more electric motors, depending on the type of car. The battery packs can be recharged as you drive, through regenerative braking or by charging them at a charging station.
More and more manufacturers have mastered the technology and the range of all-electric vehicles available today is large, as is their range.
The 2019-spec BMW i3 only travelled up to 260km on a full charge. I only managed to get about 190km back in the day.
Today, the likes of the BMW iX and Jaguar I-Pace give you a range of up to 630km and 470km, respectively, on a single charge.
Owners can recharge their car’s batteries at home overnight and public fast-chargers are becoming more common and accessible.
For perspective, recharging the BMW i4 M50’s 83.9kWh battery pack from 20% to 90% at an 80kW fast-charger took almost an hour, adding about 400km of driving range.
The i4 comes with a BMW charging card, a flexible fast-charger for charging up to 11kW and a charging cable to use in the comfort of your home.
I know what you are thinking … load-shedding. But there are work-arounds for that.
What’s best in South Africa?
Looking at the EV infrastructure in South Africa, we aren’t where we would want to be, unlike first-world countries all over the world, where electric cars dominate.
That aside, fully electric cars do not come cheap, and the lack of a subsidy from the government makes them inaccessible to the average consumer, leaving them with no option but to stick to their ICE-powered vehicles.
Hybrids and plug-in hybrid cars are the best solution for now but they are more expensive than already-pricy ICE cars, however, they are more affordable than going full electric. Just think of the long-term fuel savings …
Until we solve our EV infrastructure and power problems, hybrid and plug-in hybrid cars make a world of sense in SA.
