Best hybrid cars for 2022

We reveal the best hybrid cars that combine effortless ease of use with impressive fuel economy. We've also uncovered hybrids with terrible motorway mpg and worrying emission levels.

The best hybrid cars can be a good choice for drivers looking to save on fuel costs, but who don’t want to plunge into the deep end with a fully battery-powered electric car.

Demand for hybrids is rising rapidly, with ever more car manufacturers offering the choice of a hybrid engine alongside petrol and diesel.

There are plenty of options available — handy if you'd rather avoid the peculiar styling (or indeed Uber driver connotations) of the pioneering Toyota Prius. From the compact Honda Jazz to full-fat, sporty plug-in hybrid off-roaders such as the Porsche Cayenne E-Hybrid, there's now an electrified model to cater to every taste.

However, not all hybrids are built equal. We've tested models with disappointing reliability, surprisingly high emissions, and many that simply won't give you the promised fuel economy when you actually get them out on the road.

Get the definitive verdict on every car we've tested, across all fuel types, with our independent car reviews.

What is a hybrid car?

A hybrid car combines a conventional engine (usually petrol, but diesel hybrids are also available) with an electric motor. Depending on the type of hybrid, the electric motor works alongside the petrol engine, or by itself for short periods, with the aim of saving fuel and lowering exhaust emissions.

Below are the very best hybrid cars we've tested, including the best SUV, best cheap hybrid and best plug-in hybrid (PHEV). These are all fantastic cars. Not only have they sailed through the same tests as their traditional petrol and diesel rivals, but they could also save you an impressive amount on fuel costs.

Best SUV or 4x4 hybrid

  • 74%
    • best buy

    The latest version of this popular model ditches diesel altogether and is available solely as a petrol hybrid. That’s no bad thing at all. Not only is it quiet and effortless to drive, it’s also proved very economical, with improved fuel consumption on the motorway – typically a weakness for hybrid models. Only a clunky infotainment system lets it down slightly.

Types of hybrid car

There are three main types of hybrid car. The best for you will depend on how you use it and – crucially – whether you can easily install an at-home charging point to top up the battery that powers a hybrid's electric motor. 

Full hybrid cars 

Full hybrids, also known as 'self-charging' hybrids, are petrol (and to a far lesser extent diesel) cars with a battery pack that is separate from the standard 12V car battery. This battery is charged using energy recuperated while braking or coasting, and is then used to power a small electric motor. 

The electric motor can power the car’s wheels in conjunction with the petrol/diesel engine, or even by itself (although typically only for short distances and at moderate speeds).

The electric motor is particularly useful when the car is at its least efficient under petrol or diesel power, such as when setting off, and can sharply cut fuel use during stop-start driving in town. Some hybrids will also charge the batteries directly from the petrol/diesel engine under certain conditions.

Some newer full hybrid models make use of their petrol engine to simply charge a battery pack, which is then used to drive the wheels, as this is deemed by some manufacturers to be more efficient. In some cases - as with the Honda Civic e:HEV - the petrol engine can power the driven wheels, for instance when quicker acceleration is called for.

Pros of full hybrids

  • Full hybrids don't need to be plugged in to charge their batteries.
  • More convenient if you don't have easy access to a charging point.

Cons of full hybrids

  • Very limited electric-only range.
  • Fuel savings compared with a traditional petrol or diesel are likely to be small, particularly if you mainly drive on motorways.

Plug-in hybrid cars 

Mitsubishi Outlander plug-in hybrid car

Plug-in hybrids (PHEVs) - pioneered in the UK by models such as the Mitsubishi Outlander PHEV - have much larger batteries than full hybrids and have a much longer electric-only range – normally around 20 to 40 miles. However, to get anywhere near the advertised fuel economy for most models, you'll need to plug it in to charge the battery as much as possible.

Most PHEV models can also use the engine to charge up the battery, but this is much less efficient. When the battery is depleted, PHEVs work like a full hybrid.

Our research has revealed that, compared with fully electric cars, PHEVs tend to use more electricity due to their weight and smaller electric motors. If you can regularly plug in a car at home, you may want to consider moving straight to an electric car.

How long does it take to charge a plug-in hybrid?

The amount of time it takes to charge a plug-in hybrid car’s battery will depend on both the size of the battery and the speed of the electric charger. If you're charging at home, it could take several hours. At rapid-charging stations it could take less than an hour.

Pros of plug-in hybrids

  • A longer electric-only range, as they have larger batteries than standard hybrids.
  • If charged regularly and used for short journeys only, plug-in hybrids can be largely emission-free.
  • The combination of battery and petrol power should improve fuel economy for reasonably long journeys, provided the battery is charged when you set off.

Cons of plug-in hybrids

  • You have to plug cars in regularly for the best fuel economy – this may make it inconvenient and expensive if you don't have easy access to a charger.
  • Like all hybrids , PHEVs still burn traditional fuel, so don't expect any hybrid model to have a 0g/km official CO2 rating.
  • Plug-in hybrids can be heavy, which can have an effect on ride quality and suspension.

Mild-hybrid cars 

The main difference from full and plug-in hybrids is that mild hybrids can’t be driven on electricity alone. The battery is only there to assist the combustion engine, not take over from it. That limits their potential for low CO2 emissions and fuel consumption. 

Some give extra power under acceleration; others let the engine be turned off when braking or coasting to save fuel. The mild-hybrid battery can also work with the car’s regular 12V battery to power non-engine systems, such as the car’s air-conditioning.

You’ll probably not notice much of a difference between driving a mild hybrid and a regular petrol or diesel car. The exception is that, while modern cars cut the engine while stationary to reduce fuel consumption and pollutants, in a number of mild hybrids the engine will cut out while you’re coasting or decelerating. 

So if you were slowing down for a set of traffic lights, for example, at low speeds the engine will cut out while you’re still in motion and won’t kick in again until you release the brake and need to accelerate. It can feel a bit weird at first, coasting to a complete stop without the engine on, but you’ll quickly get used to it.

Popular mild hybrids include the Volvo XC60, Mazda 2 and BMW 3 Series.

Pros of mild hybrids

  • The electric motor can assist the combustion engine, affording you more acceleration and potentially smoother power delivery under certain conditions, such as when you’re pulling away from a stop.
  • Unlike full and plug-in hybrids, they're often available with a manual gearbox.
  • Mild hybrid models are typically cheaper than comparable full hybrid alternatives.

Cons of mild hybrids

  • You can't drive on electricity alone
  • Limited positive impact on CO2 emissions and fuel consumption, depending on the model.

How do hybrid cars help the environment?

Hybrid cars run on both fuel and electricity, so in theory they should reduce the amount of petrol you use while driving. This in turn means the car will emit a lower amount of CO2. 

However, it really does depend on how you use your hybrid car. If you use the car mostly for shorter journeys, where you can run it solely off the battery, then your hybrid is likely to be better for the environment than a conventional car. But it’s important to remember that it will still be producing emissions in the same way as a normal car when it’s not using the battery. Our road and lab tests reveal the real fuel consumption figure for each car we test, in a variety of different driving scenarios.

Which is better: a hybrid or electric car?

There's no clear-cut answer to this, as it will depend on your personal circumstances. There's no denying that electric cars are better for the environment in terms of emissions, as they simply don't produce any. But they aren't right for everybody – or at least, not yet. 

Here are the main advantages of hybrids vs fully electric cars (EVs). 

Advantages of hybrids over electric cars

  • No range anxiety - with the backup of a quickly-refuelled petrol engine, you won't need to plan long journeys so carefully around the public EV charging network.
  • The batteries that electric cars rely on can take hours to charge, depending on the connection points available. 

Advantages of electric cars over hybrids

  • Your driving will be completely emissions-free; even plug-in hybrids will emit CO2 and other pollutants some of the time
  • If you charge at home and have a competitive electricity tariff, you can keep your running costs lower than any car that relies on traditional fuel. But you will need off-street parking to install an at-home charger
  • All hybrid cars are due to be phased out by 2035, as the UK aims to eliminate CO2 emissions from road transport.

Whether you're charging an electric car or a plug-in hybrid, the public charging network can be confusing, thanks to all the different networks, connection types and different rates of power available. Make sense of it all with our guide on how to charge an electric car, which also covers charging at home.

Our independent car tests reveal an electric car's real range, so you can get a clear picture of just how far you can go on a single charge – see our best electric cars.

Which hybrid cars are exempt from the London congestion charge and other clean air zone charges?

ULEZ emission zone sign

As they're powered by petrol or diesel (at least some of the time), hybrid cars can't be considered free of exhaust emissions in the same way that a fully electric car can. This can have implications when driving into clean air zones or other restricted areas of busy cities.

Hybrid cars, including PHEVs, are no longer exempt from the London Congestion Charge, though you won't currently have to worry about the capital's larger ULEZ (Ultra Low Emissions Zone).

Only fully electric cars are now exempt from the London Congestion Charge. It's important to remember that exemptions aren't automatically applied either – you have to register your car with Transport for London first. If you haven't registered your car, you'll still be liable for the charge.

Currently, other clean air zones, such as those launched in Bath and Birmingham, only concern petrol cars made before around 2005, so the vast majority of cars aren't affected. This may change over time, however. 

Are hybrid cars being phased out?

Yes, and it's happening sooner for some hybrids than others. 

It's part of a package of green initiatives to help meet the UK’s legally binding target of reaching net zero emissions (by 2045 in Scotland, and 2050 in the rest of the UK). 

There are two key dates to keep in mind in relation to hybrid cars. 

From 2030, the sale of some new hybrids will be banned, along with fully petrol and diesel cars. This will include a ban on the sale of all new mild hybrids and, probably, some other hybrid models. 

From 2035, the sale of all new full- and plug-in hybrids will be banned. From this date, the only new cars you can buy will be zero-emission cars. This includes fully electric cars plus zero-emission alternatives, such as hydrogen cars. 

According to government guidance on the ban, there is a rather grey area around exactly which full- and plug-in hybrid models will be banned from which of these two dates. According to the gov.uk website: 'Between 2030 and 2035, new cars and vans can be sold if they have significant zero emission capability, which would include some plug-in and full hybrids'.

Are hybrid cars more reliable? 

Hybrid cars include both a combustion engine and electric motor, so it’s easy to assume there's twice as much to go wrong. But that's not true.

Most have CVT ‘gearboxes’ that never disengage, which means less wear than a conventional manual or automatic transmission. There’s also no need for a starter motor or clutch. 

The strength of the electrical power provided by a hybrid means that the petrol engine shouldn't be as stressed as a typical combustion engine, and means the manufacturer can choose to use a lighter petrol engine that revs lower.
