2016 victory empulse tt all-electric motorcycle street-ready.

Aug 24, 2015

victory-empulse1

Kudos for getting this bike street-ready so quickly. Victory Motorcycles unveils their first all-electric motorcycle, the 2016 Empulse TT. A few previously announced all-electric notables, i.e., Harley-Davidson LiveWire and Mission Motors are still concept prototypes. This bike is really a slightly modified Brammo Empulse – Victory bought the Brammo motorcycle business in January 2015 and very little has changed in the Victory model except for a notable modification of reducing the Brammo 180-section rear tire to a 160 rear tire – a size seen on the race circuit. A lithium-ion battery pack gets a 10% boost in capacity (now rated nominally at 10.4 kilowatt hours), a new seat material and a rubber damper drive setup in the sprocket to ease abrupt throttle transitions.

Powering the machine is a permanent magnet ac (PMAC) motor. PMAC motors are suitable for variable or constant-torque applications, and this flexibility also makes PMACs suitable for variable-speed operation requiring ultra-high motor efficiency. But this efficiency does not necessarily help the driving range. This is really a city bike with a 60-mile range. A controversial feature is a six-speed transmission. This is the only electric that has a transmission, all others use clutchless direct drives. The gears put a 10-15% drain on efficiency.

Waiting to see if second generation TT will have improved styling, a belt-drive to mirror the almost silent motor and will it still sport the 6-speed gearbox. But hey, looking good in this video…

Fiskar Karma. Ready to go plug-ins.

Mar 2, 2009

While we wait for “plug-in” Volt and Prius to arrive in 2010 there are two exotic automakers ready to go. Tesla ( $128,000 USD two-seater ) and Karma ( $87,900 USD ) Let’s look at Karma.

“The Karma’s material philosophy balances sensuality and accountability,” Fisker says. “We have gone to great lengths to use only environmentally conscious, classic automotive materials that support a commitment to our eco initiatives.”

Under the skin, the 4-door and 2-door cars use the same gas-electric drivetrain, which Fisker calls Q-Drive, developed with help from Quantum Technologies. The Karma will work much like the Chevrolet Volt, delivering 50 miles of all-electric range before the 2.0-liter turbocharged four-cylinder engine kicks in to drive a generator that will recharge the 22.6-kilowatt-hour lithium-ion battery and provide juice to keep the car moving. A rooftop solar panel on the sedan comprised of 80 cells divided into four zones. Output is 130 watts, and it helps charge the battery and, when the car is parked, keep the interior cool. Toyota’s got something similar on the 2010 Prius it unveiled a few hours before the Karma S broke cover.

Beneath the car’s aluminum-and-composite body lies an aluminum spaceframe chassis that cradles two electric motors that together produce 300 kW (408 horsepower) and a stunning 959 foot-pounds of torque. Fisker claims the sedan, which weighs 4,650 pounds, will do zero to 60 in 5.8 seconds. Top speed is limited to 125 mph.

Although the Karma’s electric drivetrain is a proprietary system designed in conjunction with Quantum Technologies, the engine, air-conditioning system, steering column and other “bits and baubles” were pulled from the GM parts bin, says Fisker spokesman Russell Datz.

Fisker may be getting help from GM, but, like Tesla Motors, he’s bringing a new business model to the auto industry.

His company isn’t financed by stockholders or government loans, but by venture capitalists, including the powerhouse firm of Kleiner, Perkins Caufield & Byers. It is outsourcing much of the work to top-tier suppliers like Edag Engineering and Magna Intier, and the cars will be assembled by Valmet, the Finnish firm that builds cars for Porsche. Fisker Automotive bought a big share of Advanced Lithium Power, so it’s got a battery supplier lined up.

Still, Fisker still has to get its car certified by the feds — an arduous task that some industry insiders doubt it will complete before the end of the year, particularly since we haven’t seen running cars. It also has to establish a dealer network, but Fisker says 40 dealers will be up-and-running by year’s end. Some seasoned industry watchers say Fisker undoubtedly will get his cars built, but they aren’t betting he’ll do it by the end of the year.

The convertible added just 15 percent to the cost of building the sedan, which carries a retail price starting at $87,900. Another $18,599 gets you the “Eco-Chic” model, which has an interior free of all animal products, with woodwork made from submerged logs (no clearcutting required).

Fisker says he’s received orders for 1,300 vehicles, and he tells The New York Times his company would turn a profit if it sold 4,000 cars annually. The goal, he says, is to sell 15,000 worldwide each year.

Specification:
All electric with range extender (Q-Drive)
Dual mode option: power mode and stealth mode
0-60: under 6 seconds
Top speed: 125 mph
4-door
22 inch wheels

Producer: Karma by Fiskar

Designed for Mission Motors, the bike was unveiled at the TED 2009 conference at Long Beach, California, today.

The announcement formally debuts Mission Motors, a San Francisco-based company geared to redefine the world of performance motorcycles. The company was founded in 2007 by entrepreneurs Forrest North (CEO), Edward West (President), and Mason Cabot (VP of Engineering).

Building on their backgrounds in engineering, a desire to develop clean vehicles, and a passion for motorcycles, the Mission Motors founders developed a proprietary high energy lithium ion battery pack that could provide both the range and acceleration needed for a high performance sportbike. The company (named Hum Cycles at the time) placed second in the transportation category of the 2007 California Cleantech Open, the largest cleantech business plan competition on the West Coast.
