Hybrid

San Francisco's Aura Aerospace is working on a remarkably odd idea: replacing batteries in electric VTOL air taxis with high-powered "Powercell" ultracapacitors capable of massive power output and 10-minute charging, in long-range hybrid setups.

It's been a long time since the P1, but McLaren has finally brought a hybrid supercar into full production. The 671-hp Artura introduces an all-new 120-degree twin-turbo V6, with electric assistance, and a whole new, smarter, vehicle platform.

We're all hoping for electric VTOL aircraft, but France's Ascendance isn't willing to wait for batteries and hydrogen to break through. The company says its Atea hybrid will deliver long-range VTOL travel with just 20 percent of a helicopter's emissions.

When the current-generation RAV4 crossover was introduced in 2019, Toyota promised both a hybrid and a plug-in hybrid option. We’ve driven both as 2021 model year offerings. Here’s what we learned about Toyota’s electrified RAV4s.

Shifting to alternative propulsion technologies could go a long way toward cleaning up the pollution created by the aviation sector, and a new design by MIT scientists could cut as much as 95 percent of a plane’s harmful nitrogen oxide emissions.

BMW has been slowly electrifying all of its vehicles. The small X3 crossover has been a popular staple in the automaker's lineup for a few years, offering family-sized luxury with BMW’s signature driver’s focus. Now the X3 has a plug-in option, the X3 Hybrid.

Switzerland's Manta Aircraft is working on a flexible hybrid-electric canard aircraft design that will be capable of VTOL or efficient STOL operations. A one-third scale model has been built, and the team is preparing for its first flight tests.

Although quadcopter drones may offer relatively good battery life, their hexa- and octocopter counterparts can lift heavier loads. The xFold drone can go either way, however, with extra propeller arms that can be attached or detached as needed.

Modern-day Audi motorsport participation began with rally racing back in the 1980's. But Audi never raced in the toughest of them all: Dakar. That changes in 2022, as Audi plans a debut with an electrified Dakar car that looks to be a snarling beast.

Hybrid dual-powertrain motorcycles can't possibly work ... Or can they? Kawasaki has thrown its considerable resources behind the problem, and has now released video footage of a very tidy-looking hybrid prototype on a dyno.

From 1935 to 1948, French manufacturer Avions Mauboussin was known for its light sporting aircraft. Its name has now been revived, by a French startup that plans on building hybrid STOL (short take-off and landing) airplanes.

Florida's XTI Aircraft has ben working on its TriFan eVTOL concept for at least five years, and while a passenger version is still the key focus, the company has now put forward a long-range, autonomous diesel-hybrid cargo variant.
