Hybrid

The fuel efficiency of pickup trucks has improved significantly over the past decade. We drove the 2020 Ram 1500 in both of its higher-efficiency powertrain options – the eTorque mild hybrid and the EcoDiesel turbodiesel – to see how they stack up.

As is the case with electric cars, battery range is still very much an issue with pure-electric aircraft. Hybrid propeller-drive systems are perhaps a better way to go – for now – and a new one was recently the subject of a successful test flight.

The bulk of this 1,250-horsepower hypercar's prodigious power comes from a tiny 2.88-liter twin turbo engine. Revving at 11,000rpm, it makes nigh-on 950 horsepower, making it the most power-dense production engine in the world at 329 hp per liter.

Silicon Valley-based hybridization shop Vonnen and Wisconsin custom builder Kelly-Moss give the already virile 911 Turbo S a boost of electric power thanks to a plug-and-play hybrid kit, while a sleek, safari-style update adds a rally-ready look.

It was just last month that Hybrid Air Vehicles announced the planned production version of its Airlander 10 airship. At the time, the company mentioned an optional electric propulsion system – more details on that system have now been released.

Last year, Toyota debuted a new all-wheel drive variant of the Prius. The announcement made headlines, and the car was shown throwing snow and getting slushy with its new-found all-wheels-turning capability. That’s not what happens in the real world.

This sweet-looking electric motorcycle has a relatively small, lightweight 9-kWh battery, and yet it boasts a 300-km (186-mi) urban range and superbike-level acceleration thanks to an ultracapacitor hybrid system unlike anything we've seen before.

French company Efesto has built a kit that can take your 205-odd horsepower Ducati Panigale, and turn it into a 300-horse hybrid widowmaker, with a 40-minute all-electric commuting range. Unfortunately, it looks like a Hyosung with a tumor.

Europe's most popular car gets a big update for 2020. The new 8th-gen VW Golf comes in with lots of hybrid options, way less buttons, and a standard Car2X "swarm intelligence" system designed to communicate with other cars and infrastructure.

While some electric powertrains on show at IAA 2019 are found in simple everyday commuters, many of them are in full-blown performance machines.

Lamborghini Sián couples a screaming, naturally aspirated V12 engine with a supercapacitor-based secondary electric system.

Slovenia’s Greenline Yachts has made another addition to its family of hybrid vessels, announcing a new 45-footer (13.5-m) topped by solar panels.
