Suzuki Across plug-in hybrid range, MPG, CO2 & charging

A long electric range really helps here, meaning you should be able to cover most day-to-day driving in the Suzuki Across on electric power alone

Here’s where the Across really scores – its 46-mile electric range is usefully longer than many similar plug-in hybrid models; that means more time spent driving on electricity and less time and money spent at the pumps for most drivers. Many owners may even be able to do most of their weekly driving on electric power, particularly if home charging is available.

Toyota’s 2.5-litre engine is efficient in its own right, too, and the combination of petrol power and electric assistance results in a claimed average fuel-economy figure of 282mpg. Whether you hit this or not depends on just how much use you get from the electric element, but if you’ve got a home wallbox you should wake up each morning with a full battery ready to go again.

Suzuki Across plug-in hybrid range, MPG & CO2 emissions

On paper, the raw numbers are impressive: an 18kWh battery holds enough power for a significant 46 miles of zero-emissions running – enough to allow most people to complete a commute and local errands without using a drop of petrol, as long as they have the ability to charge up at home overnight.

That electric running potential feeds into official fuel-economy and CO2 emissions figures of 282mpg and 22g/km respectively. The Across' electric range also puts it in the 8% Benefit-in-Kind band – many rival plug-in hybrid SUVs can only manage between 30 and 39 miles of zero-emissions running, which sees them in the 12% band. So the running costs definitely stack up – as long as your company is happy to fork out the significant cost of the Across in the first place.

Charge time

How long the Suzuki takes to charge will depend on when your car was built. An update in April 2022 saw the Across fitted with a more powerful 6kW on-board charger (up from 3kW previously), which halves the top-up time on a conventional 7.4kW home wallbox.

Previously, a charge from dead empty to completely full from a 7.4kW home or workplace wallbox took around six hours, but newer models manage the same job in two hours and 45 minutes.

There’s no DC or CCS rapid-charging ability, but given the Across’s ability to behave as a conventional hybrid, the need to top up while out on the road will be low.
