EVDrive Demo a UTV with 4-Wheel Motor Torque Vectoring [VIDEO]

EVDrive completed development and demonstrated a powersports industry first, an "electric 4-wheel 4-electric-motor torque vectoring technology" called Terra-Torque-Drive™, specifically geared to 4-wheel off-road powersports vehicles, such as for the rapidly growing market segment of side by side Utility Terrain Vehicles or UTVs. After taking recent demo rides in the EVDrive-UTV tech demonstrator, powersports industry insiders, such as UTV OEM reps and UTV racers enthusiastically agree, that the Terra-Torque-Drive™, technology would beat almost all of today's top "gas/mechanical powered" 4wd UTVs. OEMs now have the opportunity to license this unique technology for integration into their own future powersports side by side UTV vehicle offerings.

Approximately 323,000 UTVs were retailed in North America in 2012, according to Power Products Marketing (PPM), a market research firm. PPM found consumer models (for example: Polaris RZR XP900) accounted for around 35% of total sales; Prosumer models (example: Deere XUV825i) garnered around 55% share, and commercial models (example: Bobcat Toolcat) were responsible for about 5% of sales. Industry insiders concur that the new EVDrive technology could apply to all 3 market segments. Compared to the top UTVs sold today, a Terra-Torque-Drive™, powered UTV with EVDrive Range Extender (REX) installed would excel in these areas:

1 - Highest efficiency 4wd drivetrain on any UTV today (least mechanical losses)
2 - Adjustable hill descent control (accomplished via an "electric engine braking" called "regen" putting energy back into the vehicles battery system from each of the 4 wheels)
3 - Dynamic torque vectoring modes both for high and low speed operation, e.g. industry unique "Zero Radius Turning" and high speed active torque vectoring allows for better and safer handling off-road
4 - Torque and power from -100 to +100% can be dynamically sent to any wheel, in either direction, in any combination, at any time.
5 - True Series hybrid with optimized internal combustion engine powered REX to allow for longer range matching or exceeding gas powered UTVs sold today. (REX is a high voltage specialized generator- LPG, gas or diesel powered REX engine easily adaptable, no mechanical connections to vehicle)
6 - 120vac power from onboard battery pack, backed up with the REX for general utility use
7 - Lower cost to maintain and operate - superior fuel economy, estimated average 50-100% better – for short trips, no fuel may be needed at all – plug-in to standard electric car chargers.
8 - Superior straight-line and rough loose material, curvy trail acceleration
9 - Greater river depth traversal possible due to completely sealed liquid cooled e-motors/power electronics.
10 - Stealthy low noise operation in electric only mode e.g. wildlife observation & hunting
11 - Torque vectoring software platform allows new traction capabilities to be supported like "apps" without costly mechanical NRE expenses to the OEM – OEM can provide customers software updates for new capabilities.

EVDrive chose the 4-seat Kawasaki Teryx4 as a tech demonstration platform because of its short wheelbase, smaller turning radius, and large break over angle to minimize getting hung up on obstacles. EVDrive modified this UTV with complete removal of the gas engine and AWD mechanical drivetrain and replaced with a 160hp peak total version of the Terra-Torque-Drive™. Unlike the stock Kawasaki Teryx4 UTV mechanical AWD drive, no additional mechanical losses are incurred in the Terra-Torque-Drive™, regardless of AWD mode from lack of transmission, driveshafts and differentials. "Off-road UTVs are ideally suited to our torque vectoring technology where only single fixed speed reduction is required per motor-wheel to attain 55-75mph top-speeds with the type of high RPM brushless motor technology we employ," said COO, co-founder, Steve Tice.

The Terra-Torque-Drive™, is a customized version of the general and modular EVDrive-Train architecture™ (http://bit.ly/EVD-Arch) used on all EVDrive conversion projects, with an in-house developed scale-able torque vector software platform added running on the EVDrive VCU (vehicle control unit), which supports new traction modes with inputs from all driver controls plus vehicle sensors such as accelerometers, etc. Some planned traction modes, that go beyond what is currently running on the demonstrator: auto dynamic terrain type posi-traction control, variable inclination angle offset descent control, zero radius turns on incline, emergency 4-wheel panic braking/stop & boulder climbing.

The Terra-Torque-Drive™, powered e-UTV demonstrator uses 4 of the sealed liquid-cooled EVDrive EVD35 35kW/47HP peak drive sub-systems, de-tuned to ~30kW/40HP each or delivering a total of ~160HP/120kW peak. At each motor shaft, ~66 ft-lbs peak torque is delivered. The 4 gearboxes allow ratio changes with off-the-shelf gearsets. With the currently installed single speed gearsets, at the CV joint of each wheel, a whopping 726 ft-lbs peak torque is delivered. This is the kind of torque necessary to perform Zero Radius Turns with a fully loaded vehicle and perhaps even some extreme rock climbing. "With these gearsets, a top speed of 45mph is achieved with acceleration to this speed of less than 4 seconds if you get good traction – at zero speed all 4 wheels will break loose on dry asphalt!" said EVDrive's CTO & co-founder, Bob Simpson.

In the accompanying video to this press release, some of the e-UTV tech demonstrator more technical features are revealed, such as: control touch screen for the Terra-Torque-Drive™, specifically the interface to the in-house developed VCU, shown in accompanying picture links below, and optional engine sound synthesis unit some OEMs expressed interest in, with 2 sounds demonstrated in the video, a gas turbine and V-twin motorcycle sound.

Addition of the15kW REX not only gives the UTV full performance and range to match and exceed top UTVs on the market but also offers a feature the competition does not, that is 120vac of electrical power anywhere you need it. "With the REX sub-system part of the Terra-Torque-Drive™, a hybrid UTV can be a true swiss-army-knife UTV, able to deliver power in remote locations for construction/utility/ranch applications, run silent for hunting/wildlife observation & with full-time 4wd torque vectoring, can deliver off-road handling and performance for sports/recreation, in summary, addressing all needs in the consumer, prosumer and commercial markets," said CEO, Steve Tice.

"Similar to our 25kW REX technology installed in our Series-PHEV BMW325 tech testbed -> http://bit.ly/PHEV-BMW-3-series but smaller, our custom high voltage 15kW-single cylinder (ICE) powered REX for the UTV is located between the rear seats – so with this sub-system, competing against top 4-seat UTVs in range will not be a problem - certainly the performance meets and beats stock UTVs we have tested" said EVDrive's CTO Bob Simpson. The REX gas engine can be modified to run on LPG as well offering additional emissions and operational cost advantages. EVDrive's REX technology supporting the hybrid e-UTV development has been already designed & proven in EVDrive Series PHEV BMW 325i Technology Testbed here shown sealed below rear spare tire floor - no protrusion above stock floor as shown in pictures at link included above.

EV West is partnering with EVDrive to deploy and demonstrate Terra-Digital-Torque-Steer™ all-wheel torque vectoring technology on full-size off-road vehicles. EV West is known for many milestones; e.g. Builders and drivers of the record breaking all-electric BMW 3-series street sedan at the Pikes Peak International Hill climb and builders of first ever electric off-road race car to run the Baja Mexican 1000 race in the National Off Road Racing Association's series.

2015 Porsche 918 Spyder: The Future of the Hypercars? [VIDEO]

Carlos Lago of Ignition tests the Porsche 918 Spyder in Spain.

Boasting an electric motor on the front axle and a parallel hybrid setup for the rear, this hypercar produces a combined 874 hp and 944 lb-ft of torque and aims to set a new precedent for performance and efficiency. To this end, it has dizzying amount of motorsports-derived technology -- its carbon fiber passenger tub, engine, and chassis are derived from the concepts that created the RS Spyder ALMS racecar -- but its European test cycle fuel economy results are comparable to the Toyota Yaris Hybrid's.

Tesla China chief unveils aggressive growth plan for China

Tesla Motors expects its China sales to contribute one third of global sales growth this year, a senior executive said, adding that a trademark issue stalling full-entry into China had been resolved.

Veronica Wu, vice president of Tesla's China operations, said the Palo Alto, California-based company planned to open stores in 10-12 Chinese cities by the end of 2014, including its flagship store in Beijing that opened late last year.

Wu, the 43-year-old executive who jumped ship to Tesla from Apple's China unit at the end of last year, said Tesla China had a "very aggressive growth objective".

She said the unit was aiming to contribute "30 to 35 percent" of Tesla's overall global sales growth targeted for 2014.

Wu said the company aimed to double overall total sales this year. She put global sales at 23,000 to 24,000 last year. "I have my work cut out for me," Wu said in an interview. "But I am pretty confident."

Wu discussed Tesla's plans for its Chinese sales and marketing operations at Tesla's flagship store inside an upscale shopping mall in Beijing a day after announcing its pricing strategy.

Tesla said on Thursday that a version of the Tesla Model S, a sleek all-electric battery car which sells for $81,070 in the United States, would retail for 734,000 yuan ($121,300) in China after shipping costs and import duty and other taxes. The company was referring to a Model S with an 85 kilowatt-hour battery pack.

The Beijing-born executive, who worked for Apple's China unit in Beijing from 2006 until she joined Tesla in December, said that given the Tesla car's "quality," the Model S offered "great value".

Wu applauded Beijing's support for electric and plug-in electric hybrid cars.

She said Tesla had also resolved a trademark issue that had long prevented the company from using "Te Si La" - the Chinese name best known among Chinese consumers, which Tesla wanted to use in China.

"We went to court and we won," she said. "The court has given use right to use the name, which is why you see the Chinese name in our store now."

The name had been registered by a local businessman who had refused to give up the trademark. The U.S. company had started offering its popular Model S sedans in China, but with no Chinese language name.

Wu said Tesla had no plans to start local production of its cars in China, at least for the time being.

"Right now we are not considering (that) as yet," the Tesla China chief said.

"The most important task right now, now that we have announced our pricing strategy, is to focus on getting the right car and making sure we have the right service network, and making sure the Chinese customer is happy," she said. "Happy customers are the best advocate of your product, right?"

Porsche 919 Hybrid to run turbo V4 engine

Porsche's all-new LeMans contender will feature a turbocharged V4 2.0-liter direct-injection gasoline engine.

The 919 Hybrid marks Porsche's comeback in the world of LMP1 racing and according to Autocar it has a turbocharged 16-valve 2.0-litre direct-injection V4 configuration already confirmed. It is believed Porsche opted for this configuration for packaging reasons to enable the best possible position for installing the hybrid drive system.

This petrol engine works with two energy recuperation systems called KERS and ERS which will store the energy in a battery pack until the driver presses a button to deploy it to the front wheels through an electric motor. It should be noted the V4 engine will power the rear wheels while the battery is of the lithium-ion type and has been provided by A123 Systems from United States.

Behind the wheel of the Porsche 919 Hybrid will be Mark Webber, Neel Jani, Timo Bernhard, Romain Dumas, Marc Lieb and Brendon Hartley. The vehicle will receive its racing debut on April 20 when the 2014 WEC starts at Silverstone Six Hours.

In 2014 all three works hybrid teams - Audi, Toyota and Porsche - will run All-Wheel-Drive powertrains at the 24 Hours of Le Mans (14-15 June).

Nissan and FedEx Express Put All-Electric e-NV200 to Work

FedEx Express, a subsidiary of FedEx Corp., and Nissan announced today at the Washington Auto Show that the two companies will begin testing the Nissan e-NV200, a 100 percent electric compact cargo vehicle, under real world conditions in Washington, D.C.

This test marks the first time the vehicle will be running in North America. FedEx Express and Nissan have conducted similar e-NV200 tests with fleets in Japan, Singapore, the United Kingdom and Brazil.

FedEx and Nissan are both committed to reducing the environmental impact of their operations worldwide. Rotating the Nissan e-NV200 into the delivery fleet is part of the FedEx EarthSmart program, a global sustainability platform designed to guide the company's environmental commitment in the communities where it operates. For Nissan, this effort aligns with its "Blue Citizenship" corporate social responsibility program with a focus on increasing the number of vehicles that emit no greenhouse gases by exploring additional vehicle segments where its leading electric vehicle technology may be applied.

FedEx will deploy the Nissan e-NV200 in the Washington, D.C. area, where it will undergo field tests that subject it to the routine requirements of a delivery vehicle. The results will be used to help determine the viability of using an electric vehicle in this role in the U.S. Nissan e-NV200 is scheduled to begin mass production later this year in Europe.

"As a global fleet operator serving 220 countries and territories worldwide, FedEx is committed to improving the efficiency of its vehicles as part of our EarthSmart initiatives," said Mitch Jackson, vice president of Environmental Affairs and Sustainability, FedEx Corporation. "We are pleased to continue our work with Nissan and bring the e-NV200 into test in North America."

"We're eager to work with FedEx and other companies to put the e-NV200 through its paces to continue to build awareness of the capability of electric vehicles and to evaluate how well it meets the needs of the commercial consumer," said Erik Gottfried, Nissan director of Electric Vehicle Sales and Marketing. "We'd also like to explore clever uses of EVs in work environments where carbon emissions of gas-powered vehicles make them impractical or impossible to use."

Nissan's Second Global All-Electric Vehicle

Following Nissan LEAF, e-NV200 will be the second EV that Nissan markets globally. The all-electric compact cargo vehicle strengthens Nissan's leadership in zero emission mobility. The 100 percent electric model offers the same versatility, functionality and roominess as its gasoline-powered sibling. The e-NV200 delivers unique, emission-free and quiet performance thanks to a powertrain based on Nissan LEAF and the same advanced lithium-ion battery. It emits no carbon dioxide, compared to approximately 140 g of CO2/km emitted by gas-powered engines in a similar vehicle. The e-NV200 can be charged up to 80 percent of its full capacity in less than 30 minutes when equipped with a quick charge port and using a fast charger.

With front-wheel drive, the e-NV200 provides rapid and smooth acceleration and excellent handling with a high degree of maneuverability. The electric vehicle delivers immediate torque, which benefits acceleration with a heavy payload from a dead stop. The e-NV200 offers the low cost of ownership that EVs such as LEAF boast—based on fewer maintenance requirements and the reduced cost of charging versus fueling. The smart positioning of the battery ensures a larger cargo area, and the vehicle maintains a low load floor, key considerations for light commercial vehicles.

FedEx: The EV Global Fleet

FedEx Express currently has 167 electric vehicles and 365 hybrid electric vehicles in the United States, France, Germany, Italy, Japan and China, including the units that will be deployed in Brazil starting in January. By the end of this fiscal year (May 31, 2014), the company plans to increase these numbers to 222 and 393, respectively. From 2005 to 2012, the introduction of this type of vehicle in the fleet enabled the company to save nearly 2.4 million liters of fuel.

Initiatives like this, aligned with others, such as matching the right vehicle to the right route, buying vehicles with the right-sized engines and inclusion of light vehicles into the fleet, have allowed FedEx to quickly progress towards its goal of increasing the fuel efficiency of its fleet, which the company revised in the beginning 2013 by increasing its initial improvement target from 20 percent to 30 percent by 2020.
