Hybrids could have almost as much potential in the air as they do on the ground. Ampaire says the clever first-gen hybrid powertrain in its Electric Eel demonstrator cuts fuel consumption by 50-70%, and it's just logged a world record for endurance.

Electric touring is officially on the menu ... Sort of. Evoke has built its 6061-GT electric motorcycle around the biggest battery pack ever offered in a production bike: a staggering 30-kWh monster offering more than 600 km (370 miles) of range.

If you want an electric boat to get very far, you either need huge amounts of battery, or you need to lift your hull out of the water on a hydrofoil system to cut down energy-sapping drag. The SpiritBARTech35EF does both, for record-smashing range.

It’s no secret that sauropods had really long necks, but now paleontologists claim to have identified the species that takes the crown. According to the team, Mamenchisaurus has the longest neck of any known animal ever, measuring 50 ft (over 15 m).

Those nervous of heights should definitely steer clear of the newly completed 516 Arouca bridge. As its name suggests, it spans a total of length 516 m and is hailed as the world's longest pedestrian suspension bridge by Portuguese officials.

With perhaps a few exceptions, battery-electric multicopter drones typically can't fly for longer than about 30 minutes. Such is not the case, however, with their hybrid counterparts – one of which recently broke its own endurance record.

​​A new suspension bridge has just opened that might give Indiana Jones himself sweaty palms. The world's longest pedestrian suspension bridge takes visitors through the scenic Bernese Alps, with the mighty Matterhorn mountain in the background to draw nervous eyes away from the valley below. ​

A future where drones drop off your online orders is another step closer this week after a new record was set for the world's longest drone delivery. On May 5, a fixed-wing HQ-40 UAV carried a package more than 97 miles, under the watchful eye of the Nevada Institute for Autonomous Systems (NIAS).

Qantas is to become the first commercial carrier to offer regular non-stop flights directly from Australia to Europe, using the new Boeing 787-9 Dreamliner. The 14,498 km trip will take around 17 hours, and be the longest direct flight service for a Dreamliner anywhere in the world

A tunnel through the Alps in Switzerland that has taken 17 years to build officially opens today. The Gotthard Base Tunnel stretches for 57 km (35 mi), making it the longest rail tunnel in the world. It is also the world's deepest rail tunnel.
