We've all seen pictures of damaged phone batteries, and the 1937 Hindenburg airship disaster didn't exactly give hydrogen a great name. So are concerns about hydrogen and electric cars warranted? Independent safety body Euro NCAP's latest crash tests thankfully suggest there's no need to worry. Both new hydrogen and electric cars have excelled in its tests - find out which these are below.
Euro NCAP, partly funded by Which?, has tested the new second-generation Toyota Mirai saloon, one of just two hydrogen cars currently available to buy in the UK. When it crashed the car several times in its tests, Euro NCAP scrutinised carefully whether its high-pressure hydrogen tank posed any concerns. This is the second hydrogen powered car Euro NCAP have tested following the rival Hyundai Nexo in 2018.
Meanwhile, Euro NCAP has also tested the Audi Q4 e-tron SUV, which is built on Volkswagen's MEB platform, shared with a wide range of Volkswagen Group cars.
If hybrid cars are more what you're looking for, Euro NCAP newly rates the Ford Kuga plug-in hybrid, and also the traditionally-powered Subaru Outback petrol estate.

Euro NCAP says that with the Mirai having a high-pressure hydrogen storage tank, 'safety is of paramount importance' and so it 'paid extra attention' to the car's crash test safety.
Nevertheless, the Mirai sailed through Euro NCAP's demanding assessments achieving a perfect five stars out of five, with it concluding that 'the fact it's powered by hydrogen had no effect on its inherent safety.'
In fact, the car scored a strong 80% or more in all four of Euro NCAP's test categories, from adult and child safety to protecting vulnerable road users like cyclists and the car's safety assistance systems, including automatic braking to reduce the speed of impact when it detects a collision is imminent.
While Euro NCAP never crash tested the original Toyota Mirai, this new result follows promising results for the first hydrogen-powered car Euro NCAP ever tested, the rival , in 2018. It too was awarded a full five stars out of five, scoring 80% or more in three areas, and the one it performed a little worse on, scoring 67% for protecting vulnerable road users, wasn't due to it being a hydrogen-powered car.
Just like these two cars, the Audi Q4 e-tron achieves the maximum five stars out of five in Euro NCAP's tests. It performs particularly strongly at protecting adults in the car, scoring 93% in this category.
While still reasonable, its weakest area was protection for vulnerable road users, where it scored 66%. Its autonomous emergency braking system, which reduces the speed of impact in imminent collisions, was rated as adequate in protecting pedestrians, but only marginal for cyclists. Nevertheless, this was still enough for the car to get the full five stars in Euro NCAP's tests.
Euro NCAP originally crash tested the Ford Kuga mid-size family SUV in 2019, and its experts have determined the new plug-in hybrid version is sufficiently similar for it to carry over the same maximum rating for it of five stars out of five.
Back in 2019, the car performed strongly in all areas, scoring an exceptional 92% in protecting adults in the car. Its safety assistance systems got the lowest rating, a still-good 73%, with Euro NCAP noting there's poor protection for pedestrians if they hit the windscreen pillars in a front-on collision.
In contrast to the Ford Kuga, safety assistance systems are far from a weaker area on the Subaru Outback estate, the only conventionally-powered car Euro NCAP tested this month.
In this area, the Outback scores an outstanding 95%. It has a cutting-edge system that detects signs of fatigue or impairment directly from the driver's eye movements, and if this leads to unusual steering behaviour, it issues a warning when it believes the driver requires a break. This technology is expected to become more widely used in new cars over the coming years.
The Outback also scores the maximum five stars out of five in Euro NCAP's tests, rounding off superb performance from the cars assessed by the safety body this month. The Outback had no serious areas of weakness, with its lowest-scoring area, vulnerable road users, still getting a high 84%.
The Outback is no ordinary estate car: it's a rugged off-road oriented 4×4, with higher suspension and extra body cladding than a typical car. Like all Subarus, it's four-wheel drive.
