Citroen bringing hybrid air powertrian to Geneva in C3 VTi 82

Clever. The air hybrid powertrain that Citroen will be bringing to the Geneva Motor Show next month is nicknamed N-Air-Gy. Or, at least, that's what it says in the rendering that Citroen released today in preparation for the Swiss event. We've heard about this technology be

Autocar launches E3 hydraulic hybrid garbage truck

At Waste Expo 2011, Autocar announced the commercial launch of its E3 hydraulic hybrid chassis cab. The launch of this advanced hybrid follows the successful implementation of a pre-production fleet of E3s that have been hauling away waste in southern Florida since September of 2010.

Chrysler working on hydraulic minivan hybrid with the EPA's help

Chrysler Group CEO Sergio Marchionne and Lisa Jackson, Agency Administrator for the EPA, announced a new research project to bring hydraulic hybrid technology to the marketplace. The new hybrid will be based on Chrysler's Town & Country minivan, although this shouldn't be confused with the other minivan hybrid Chrysler is working on

Hydraulic minivan coming from Chrysler, with the EPA's help

The closest Americans can get to a hybrid minivan in 2011 – an entirely practical vehicle if there ever was one – are the Prius V and the 2012 Ford C-Max, both of which are due later this year but are not really minivans. This will sort of change in

What could have been: DeLorean had reportedly been planning hydraulic hybrid

The name John DeLorean is synonymous with the automotive industry. From his days at General Motors, where he turned Pontiac into the automaker's de facto performance division with the creation of the GTO, and, therefore, the muscle car genre in general, to his days running his eponymous car company that gave

New York trash trucks start testing Bosch Rexroth hydraulic hybrid

The New York sanitation department has just started a year-long evaluation of a hydrostatic regenerative braking (HRB) system on garbage trucks. The system provided by Bosch Rexroth is a hydraulic launch assist system. This is basically a hydraulic mild hybrid system. During braking, a hydraulic pump is driven off the gearbox to pressurize an accumulator. When the vehicle accelerates, the hydraulic pressure is used to drive a hydraulic motor that provides a mechanical assist to the transmission.

What is regenerative braking?

Ah, fire. One of humanity's oldest ways to generate energy. Technically, you could generate energy by burning brake pads, as seen in the picture above (thanks, Flickr!), but automotive engineers have managed to come up with a way to use brakes to generate energy without going up in flames. The technology is called regenerative braking and it's the subject of this week's Greenlings.

Lightning Hybrids to reveal LH4 at Denver Auto Show

The Denver International Auto Show opens today and Lightning Hybrids is planning on being there to display their biodiesel hydraulic hybrid prototype, the LH4. If you happen happen to be attending the opening this afternoon, don't be surprised if the slick gray sportster smells a bit like wet paint, since the family-of-engineers-run company was rushing to complete work on the vehi

Lightning Hybrid to go for X-prize with 100 mpg biodiesel hydraulic hybrid

A small startup company in Loveland, Colorado is working on what it hopes will be the keys to the Automotive X-Prize. Lightning Hybrids is building a pair of vehicles, one with three wheels and the other with four, that use a biodiesel-fueled hydraulic hybrid powertrain. Not a lot of details are available right now, but from what can be gleaned on the website, it appears to be a series hybrid system with a compact 90 hp two-stroke diesel engine paired with a hydraulic drive system. The site list

California ARB approves $700,000 in grants for green tech demos

The California Air Resources Board this week approved $700,000 in grants for demonstration projects to evaluate clean air technology. Advanced Transit Dynamics, Eaton and the Sacramento Municipal Utility District will each receive over $200,000 for projects. Eaton will build a package delivery van using a hydraulic series hybrid system it has developed. Similar systems have also been developed and tested by several other companie

Artemis Intelligent Power demostrates hydraulic hybrid BMW 530i w/Video

The concept of a hydraulic hybrid powertrain is not a new one, and a number of companies have developed prototypes. The latest to show off a vehicle so equipped is Artemis Intelligent Power in the UK. The company has put together a BMW 530i demonstrator using its Digital Displacement pump/motor technology. The layout is very similar, in principal, to that used by FEV on its experimenta

Eaton developing hydraulic hybrid systems

Eaton, a company primarily known for making superchargers that make your vehicle go like stink, but guzzle even more gas, is also in the series hydraulic hybrid (SHH) business. The drive system in a hydraulic hybrid replaces the conventional drivetrain; the engine is effectively rendered a "pump" for the hydraulics, and energy is stored in two different accumulators that then power the wheels. Fuel savings of 50-70% are achieved by the system being much lighter than a traditional drivetrain, alo

Waste Management tries out hydraulic hybrids

Waste Management, the garbage-collecting giant, is adding 4 hydraulic hybrids to its Fort Worth fleet for a bit of field testing. The trucks, which were launched about 6 months ago, are from Peterbilt and use the Eaton Hydraulic

UPS orders up hydraulic hybrids from Eaton

While UPS is one of the companies that will test a hydraulic hybrid vehicle (HHV) from Hybra-Drive sometime next year, it has already done testing with a similar type truck from Eaton. The initial 18-month trial saw upwards of 50 percent less fuel burned and was positive enough for the delivery giant to order up seven of the HHVs. UPS calcul

Hybra-Drive hydraulic hybrid to undergo HTUF testing

It's not often that a Hummer is pictured here on AutoblogGreen but this particular brute, owned by hydraulic hose and belt supplier Gates, is being converted to a hydraulic hybrid using a system developed by Hybra-Drive. We introduced them to you in '07 and now that they're making some news, we wanted
