However which takes the honours?

Hyundai Ioniq Plug-in

Mannequin:  Hyundai Ioniq Plug-in Hybrid Premium SE
Worth: £26,795
Engine:  1.6-litre 4cyl petrol/electrical, 139bhp 
Zero-60mph:  9.1 seconds

Mixed with the Ioniq PHEV’s engaging £26,795 record value in Premium SE trim examined right here, is it a hybrid hero?

However you’ll should resolve if that’s definitely worth the compromise, as a result of the Hyundai doesn’t drive as sweetly because the Toyota. Its journey is just too agency, with the wheels springing again harshly over lumps and bumps; the Prius is smoother over the identical surfaces.

Additionally, the Ioniq isn’t as snug as its Japanese rival as a result of the chassis feels extra unsettled and nervous in contrast with the extra forgiving Toyota. There’s additionally extra street noise within the Ioniq, but it surely did ship first rate efficiency at our check monitor.

The Hyundai accelerated from Zero-60mph in 9.1 seconds, helped by the electrical motor’s torque enhance off the road. This instantaneous shove from the electrical motor meant the Ioniq’s in-gear figures had been additionally sturdy, accelerating between 50 and 70mph in high gear in 13.2 seconds, displaying the additional oomph delivered by the battery and motor set-up.

The gearbox’s six ratios imply the Ioniq feels extra like a traditional automobile to drive, and though it’s a dual-clutch unit, it doesn’t shift with the snappiness you would possibly count on from such a transmission. It’s principally easy sufficient, though we did expertise a couple of jerks and shunts from the gearbox round city in EV mode. At the least the punchy EV efficiency means fast getaways are okay.

Hyundai Ioniq vs Toyota Prius

It’s enjoyable to run round in EV mode, however the steering isn’t fairly as good because the Toyota’s as a result of the weightier set-up feels extra proof against your inputs.

Whereas Toyota’s commonplace Prius Hybrid is one in every of our favorite inexperienced vehicles, the Prius Plug-in has proven a couple of chinks in its armour by comparability. At £29,195, it’s costlier than the Ioniq, however does it ship greater than the Hyundai can supply?

The Prius feels extra like a hybrid on the transfer, and that’s right down to the mixing of the petrol engine, electrical motors and gearbox. The Toyota makes use of a CVT computerized transmission, which doesn’t even have any gears; as a substitute, it retains the petrol engine’s revs on the optimum level for energy or effectivity, relying in your driving type.

Some CVTs affect refinement as they ship revs hovering. It’s not so unhealthy within the Prius, and no worse than the droning engine within the Hyundai, however press your proper foot to the ground and it does get noisy.

Accomplish that and there’s respectable efficiency on supply, even when the Toyota’s 10.5-second Zero-60mph time was 1.four seconds slower than the Hyundai’s, whereas its kickdown acceleration instances additionally trailed the Ioniq’s.

The CVT means progress in electric-only mode is definitely smoother than in its rival right here, however each vehicles make an honest fist of zipping out of junctions, with easy electric-only acceleration.

The Prius’s brakes are barely simpler to modulate, however are nonetheless slightly jerky when coming to a halt. Nonetheless, other than this, it’s the comfier, extra composed and extra agile machine. The steering is sweeter, and whereas the chassis rolls slightly extra due to its softer set-up, there’s extra grip out there, mixed with a extra forgiving journey over tough surfaces.
