Honda NC700X (First Look)

Unveiled at the New York International Motorcycle Show, the Honda NC700X is a multi-purpose, versatile machine with a big emphasis on utility, perfectly timed for today’s tight economic climate.

Most impressive is the NC700X’s price, starting at an incredibly low $6999 with choice of three models: D for regular use; S for sport riding; and MT for full manual gearshift control via bar-mounted toggles.
The standard NC carries a conventional 6-speed manual transmission transmitting power via a chain final drive. However, Honda is offering a second-generation dual-clutch semi-automatic transmission as an optional upgrade. The NC700 uses two hydraulically controlled clutches to automatically pull away from a stop and to seamlessly deliver gear shifts and has a 270-degree firing interval that mimics a V-Twin feel and use a biaxial counterbalancer to quell vibes inherent from a parallel-Twin. Four valves per cylinder are activated by a single camshaft, and fuel is delivered by EFI through just one 36mm downdraft throttle body.
The engine’s long-stroke, undersquare (73 x 80mm bore/stroke) design and mild tuning emphasize efficiency rather than high performance. Honda claims a peak of 51 hp at a modest 6250 rpm rated at the crankshaft, which will likely translate into about 45 horses at its 160/60-17 rear tire. The Versys cranks out a relatively whopping 60 fillies. The NC’s torque rating of 45.7 ft-lb. at a low 4750 rpm is more impressive, promising a broad and linear powerband. Honda claims the NC700X gets a remarkable 63.5 mpg, which may translate into a range of up to 235 miles from its 3.7-gallon fuel cell.
700X also has a reasonable suspension travel, 6.0 inches from the 41mm conventional fork and 5.9 inches from the preload-adjustable rear shock. The long-travel suspension vaults the seat height from 31.1 inches to 32.7.
It has a chassis geometry of a 27.0-degree rake, 4.3 inches of trail and a 60.6-inch wheelbase. Its nimbleness is credited to its low center of gravity and mass centralization created by its inclined engine, diamond-shaped steel frame and underseat fuel tank. Its full-up curb weight is a reasonable 472 pounds while braking is supplied by a 320mm rotor up front and a 240mm disc in back
Honda has designed the NC700s to be easy to live with, especially for urban types who want a versatile commuter. Its lockable, 21-liter storage area under the ersatz fuel tank can carry lunch for 10 or a full-face helmet, and it can be augmented by optional saddlebags and a tail trunk.  Other optional equipment includes heated grips, wind-deflector kits, a 12-volt socket and centerstand.

PIVO 3, EV Concept from Nissan

PIVO 3
(Weekly Auto Review) 
PIVO 3, its eighth EV concept is what Nissan envisions to be a more "realistic" EV of the near future, An ultra-compact city commuter targeting singles and couples living in and enjoying an urban lifestyle.

Building on the pioneering PIVO 1 and PIVO 2, the new PIVO 3 concept moves from the realm of imagination into a fully-evolved vehicle that envisions life in tomorrow's cities.
Where PIVO 2 was a highly innovative vehicle that stood alone as a concept car, PIVO 3 evolves in the direction of "smart community" with greater feasibility, credibility and an extended scope of mobile performance. Nissan believes PIVO 3 is very close to what the next step in urban mobility will be.
PIVO 3 front seats
This remarkably compact EV  measures just under 3m in length and seating three in a 1+2 layout. The compact body and narrow-tread wheels with IWM (in-wheel motors) enable an extremely small turning radius with zero turn gap.  PIVO 3 can make a legal U-turn in a road only 4m wide.

PIVO 3 uses electric power and by-wire control technology to permit freedom of layout and the  elimination of many mechanical parts. It uses in-wheel motors (IWM) to give wheels great freedom of movement, and more space in the vehicle chassis.
cloud computing and infrastructure
PIVO 3 supports a life of seamless mobility, using cloud computing and infrastructure (e.g. AVP and charging facilities) to connect with the city. A "smart" personal filter selects information relevant to the current driver, location and vehicle.

With Automated Valet Parking (AVP), PIVO 3 will revolutionize the parking experience by connecting to and responding to infrastructure. PIVO 3 can park automatically in specially-equipped parking lots. PIVO 3 recharges itself or sells excess power to the grid. Later, the driver can call PIVO 3 and summon it to the driver's location using a smartphone. 
PIVO 3 backview
Side-view monitors take the place of mirrors, using Nissan's Around View Monitor system to reveal the car's surroundings and help minimize blind spots.
The center console features an ultra-wide display for GPS and other information, and together with a sub-monitor and the Robotic Agent, is positioned to interact discreetly with the driver.
