the press release from Lexus Introducing the Lexus HB (Hybrid Bicycle) Concept
Lexus has established itself as an industry leader in bringing advanced technologies to the premium car market. Now it has applied the same thinking on a smaller scale to create the Lexus Hybrid Bicycle, a design concept the captures the fundamental engineering and design values of the brand, but with two wheels rather than four.
In every aspect this is Lexus, from the L-finesse design language of the engaging and elegant frame, to the application of hybrid power, an electric eight-speed transmission and lightweight carbon fibre construction.
Lexus has brought what is one of the only two examples in existence (one black and one white) to the UK for the first time, following the bicycle's debut at the 2009 Tokyo motor show (at that show, the concept bike was shown in black).

Its arrival coincides with the announcement of Lexus's title sponsorship of the Great British Bike Ride, a four-day charity fun ride from September 1-4, 2010, that will see hundreds of cyclists following a course from Land's End to the home of English rugby at Twickenham.
Lexus has pioneered high performance, low emissions and optimum fuel efficiency with its full hybrid Lexus Hybrid Drive powertrain technology. The Hybrid Bicycle adopts similar principles, with the pedal power of the rider boosted by assistance to the front wheel from a 240W electric motor, via a 25.9V Lithium-ion battery, with a choice of Eco or Power modes. And, as with Lexus Hybrid Drive, there is an energy regeneration function that helps recharge the battery by capturing kinetic energy generated under braking.
The Lexus Hybrid Bicycle has all-wheel drive, by means of a belt system. It is equipped with an electric eight-speed Shimano internal gear system, which references the sophisticated eight-speed shift-by-wire automatic transmission of Lexus's LS 600h limousine.
The carbon fibre construction shares the same light-but-strong composite materials technology that was used on Valentino Rossi's MotoGP-winning motorcycle.

I noticed a story on a student design project for Bentley at the UK's Royal College of Art called the Aero-Ace in the always fabulous Wallpaper magazine. Definitely worth sharing, and adding to as well. The text and images below are from their January, 2010 issue, plus I've added some video and additional images and sketches from the artists.
The challenge:
"Explore a new Aerodynamic lead design direction for Bentley, develop a digital design for a Bentley coupe that speaks to lean mid 21st century tastes, and that truly embraces aerodynamics to both reduce energy consumption and form part of a future Bentley design aesthetic."
Bentley's Aero-Ace project Sam Livingstone, senior tutor in vehicle design at the Royal College of Art recently noted, ‘We are seeing a return to the prominence of aerodynamics, and the aerodynamic look, to both deliver and visually convey efficiency.”
This was the initiative behind Aero-Ace, a collaborative design project, just completed with Bentley - the objective being to explore a new aerodynamic design direction for the luxury marque. Second year RCA students were asked to identify a new vehicle direction for Bentley that would appeal to the ecologically conscious consumer.

Aided by specialist EXA evaluation software PowerFlow, their two-dimensional design proposals for a conceptual coupé needed to embrace aerodynamics in order to both reduce energy consumption and form part of a future Bentley design aesthetic.
The software simulates the aerodynamics of design at a digital model stage. The advantage being that it enables two-dimensional models to be accurately tested for their aerodynamic performance without having to make an actual real-life car.
The 11 participating students came up with very different proposals, with aero performance results ranging from CD 0.167 to 0.35. Livingstone notes: ‘There are no two that are thematically similar despite all being large Bentley coupés.’ The degree to which aerodynamics plays a role depends on the marque, although Livingston has noticed a growing trend in considering aero performance at the early stages of design.
Exacting customers now expect their cars to have unwavering stability in all conditions, offer refined driving and the sort of speeds that 20 or so years ago would have applied only to purist sports cars. ‘So aerodynamics in car design is unarguably more important than ever. However, some companies still consider aerodynamics only at the end of a programme where they merely tweak details,’ says Livingstone.
The winner will be announced on 4 February and will spend six months working at Bentley.
Deutchman has proposed the Silhouette, an electric car that announces its power through a long bonnet and muscular rear stance. ‘Like a sprinter leaving the blocks, the vehicle has a forward momentum,’ he says.

‘Bentley is associated with power and style, which I interpret as refined aggression,’ explains the designer. The second skin works as a layer to channel air away to the rear for improved aero performance.
Barbot has created an aerodynamic sports car with very thin wheels, featuring four wind turbines integrated in the wheel arches to provide the batteries with electricity. The double curved roof minimises air resistance. ‘The two-part retractable roof allows the seats to move into three different configurations: the driving position of a speedster, a coupe and a roadster, all in one car,’ says the designer.
The Spitfire was inspired by Bentley’s airplane engine-making heritage – the teardrop body shape taking direct cues from aviation. The hidden wheels work like aircraft wings helping with down force
The Mirage is a 2+2 seater electric concept car, aimed at a younger buyer. ‘With only two eyes, the Mirage shows its real identity when the blacked out headlights are switched on,’ says Seesing. ‘The vertical orientation of the lights takes inspiration from Bentley’s historic 8-litre car.’
The Speed VI aims to revive and celebrate the sporting heritage of Bentley Motors. ‘Following in the footsteps of the original Speed 6, 4½ -litre, and more recently the Speed 8 Le Mans racer, the Speed VI is created for the discerning Bentley track day enthusiast,’ says Tam.

The N(Neo fire) has been inspired by the post-neoclassical period, says the designer who has covered the wheels for enhanced aerodynamic efficiency.
TEN11 is inspired by the number of feathers in the Bentley logo - 10 on the left, eleven on the right. Heikkinen designed the electric prototype with a professional kite boarder in mind. ‘The traditional long bonnet creates a possibility to have a big storage place under it - a feature demanded by a lot of Bentley customers,’ says the designer.
Insects were the inspiration behind Nodus, with its overlapping layers on the body panel. Merriman has covered the rear wheels to aid the aerodynamics. When stationary the side windows have the ability to change to the same colour as the body for security and privacy. When the vehicle is in use the colour bleeds away to a clear window.
‘My mid-engine vision is influenced by Bentley’s racing tradition,’ says Siebourg. The teardrop cabin guides airflow to the rear, the diffuser manages to reduce the lift of the vehicle in the back, plus the low bonnet cuts back on turbulence at the front of the vehicle.
The Serenade GT is an electric sports car inspired by jewellery. The two channels between the hood and front wheels guide airflow through the body to the side, for reduced air drag. Guo explains: ‘The structure at the rear end naturally forms a two-layered diffuser, increasing the down-force from the airflow.’

The dust has settled on the Tokyo Motor Show, traditionally the outlet for the industry’s most avant-garde predictions.
2007’s debuts didn’t disappoint, although the host country’s penchant for bizarre city cars is starting to look rather less eccentric as public perception shifts in their favor.
As well as some cracking urban concepts from Honda, Toyota and Nissan, here’s Wallpaper's round-up of the show’s scattering of the bold and the brave.
Above: Lexus LF-Xh concept As a luxury brand, Lexus doesn’t dabble in the small scale. It is, however, fully committed to lowering emissions, so while the size of the LF-Xh concept was an eye-opener in these eco-conscious times, the news that the urban SUV packed the latest version of the company’s tried and tested hybrid drive was far more welcome.
The concept is sleek but not improbably so, and many elements of the design will make their way into next year’s new RX model. The wrap-around, folding interior structure seems strongly influenced by contemporary architecture.
Above: Audi metroproject quattro concept Mindful that the media’s eyes would be drawn to the more unusual fare on show, few major Western manufacturers brought all-new models to the show. Audi were the exception, and while the metroproject is ostensibly a design study, it’s actually a near production-ready version of 2009’s A1 city car.
The concept uses a mild hybrid drive to keep emissions down, while the swooping roof line gives the car an easily identifiable silhouette. The metro project also includes Audi’s new in-car remote control, a hand held device designed to control the car’s functions (try switching on the heater before you’ve even stepped out of the front door on a winter’s morning). Expect the idea to spread across the company’s entire range before long.
Above: Honda CR-Z Concept The CR-Z offered a rather more believable view of the future than most concepts on show. Standing for ‘Compact Renaissance - Zero’, the car’s anteater-like snout and extreme wedge shape all hint at a low drag shape.
Intended as a sporting take on the ubiquitous hatchback, expect elements of the CR-Z to surface in the 2009 model year, with hybrid power on board right from the start. Sadly, the neon-striped spaceship feel of the interior might not make it to the showroom.
Above: Mitsubishi i MiEV Sport A sporting variant on the Mitsubishi i, the i MiEV Sport is a low-slung fastback city car, with a scarab-shaped bodyshell and an all-electric, all-wheel drive power train.
Foam green bodywork offsets the high-tech goings on below, including solar cells in the roof and a miniature wind turbine concealed behind the grill. The two plus two is pitched at the sporting environmentalist - an oxymoronic consumer profile the auto industry is keen to cultivate.
Above:Suzuki Pixy and Sharing Coach In the future, Suzuki’s futurists expect we’ll want a car that fragments into smaller vehicles, taking each occupant a stage further on their individual journeys. This ‘sustainable mobility’ concept is embodied in the SSC, the Suzuki Sharing Coach.
Essentially a box on wheels, each SSC can contain two PIXYs, a curious personal transportation module with an upright stance and the ability to enter buildings. It’s a solution to a problem that doesn’t yet exist, but Suzuki are banking on the pod people taking over the pavements of tomorrow as a response to smog-shrouded roadways.
Above: Nissan Intima Big saloons still sell by the boatload in Asia. Nissan’s Intima looks relatively conventional but is saved from mass-market dreariness by the clamshell doors that open up the cavernous interior and the teardrop-shaped windscreen that extends high over the passenger seats.
The thought of seats that swivel round to deposit you on the pavement might appeal to Japan’s fast-ageing population, although the firm is pitching this as a, and we quote, ‘New-generation Saloon for People with a Sophisticated, Discerning Eye for Beauty’.
Above: Nissan RD/BX Nissan’s ‘Round Box’ Concept epitomises the current trend towards the toy-like, a bulked-up four-seater that features a bluff frontage and open-air top. In corporate speak that translates into a ‘Youth-Oriented Compact Convertible’, hence the emphasis on being a mobile social environment. The driver gets the usual quota of lights and dials, while the satnav system can be accessed by anyone (sure to cause a few arguments).
Above:Daihatsu Mud Master-C With its Tonka Toy moniker and four-square stance, the Mud Master-C is an almost comically cute reinterpretation of the classic go-anywhere utility vehicle. Reminiscent of any number of ultra-tough models from the classic Unimog onwards, the Mud Master-C was actually developed in collaboration with one of Japan’s leading mountain bikers, Raita Suzuki, as a ‘support vehicle.’ Deliveries never need be delayed again.
Above: Toyota RiN / Toyota Hi-CT While Toyota’s 1/X hybrid concept was relatively conventional, the company let loose its creative juices with the RiN and Hi-CT. The latter was a joystick-steered, mini utility vehicle, with an upright cab and space on the back platform to haul anything you please. Plug-in hybrid drive comes as standard.
The RiN was even more avant-garde, a push-me-pull-you style urban vehicle inspired by tea houses and the dream of zero emissions. The white bodywork was decorated with organic forms, and the green carpet was a not-so-subtle way of turning the driving experience into a soothing walk in the park.
Japanese car company developing a car with built-in sensors to detect drunkenness of driver, locking ignition if needed. OPPAMA, Japan (Reuters) --
Beer-breaths, beware.
A new concept car with breathalyzer-like detection systems may provide even greater traction for Japanese efforts to keep impaired drivers off the road.
Nissan's alcohol-detection sensors check odor, sweat and driver awareness, issuing a voice alert from the navigation system and locking up the ignition if necessary.
Odor sensors on the driver and passenger seats read alcohol levels, while a detector in the gear-shift knob measures the perspiration of the driver's palm when starting the car.
Other carmakers with detection systems include Sweden's Volvo , which has developed technology in which drivers blow into a measuring unit in the seat belt before an engine can start.
But Nissan's car includes a mounted camera that monitors alertness by eye scan, ringing bells and issuing a voice message in Japanese or English if a driver should pull over and rest.
The car technology is still in development, but general manager Kazuhiro Doi says the combination of detection systems will ultimately keep an eye on who's behind the wheel.
"We've placed odor detectors and a sweat sensor on the gear shift, but for example if the gear-shift sensor was bypassed by a passenger using it instead of the driver, the facial recognition system would be used," said Doi.
Also keeping a short leash on drivers, car seat belts tighten if drowsiness is detected, while an on-road monitor checks if a car is keeping its lane properly.
Japan's No. 3 carmaker, which competes with Toyota and Honda, has no specific timetable for marketing, but aims to yoke all technology to cut the number of fatalities involving its vehicles to half 1995 levels by 2015.
Nissan's Doi says they still have to distill exactly what impairment means: "If you drink one beer, it's going to register, so we need to study what's the appropriate level for the system to activate."
Odor Sensors placed throughout the car detect the presence of alcohol and a facial monitoring system can recognize drowsy and drunken behavior.
Shift Knob Sensor:
1) A hi-sensitivity alcohol odor sensor is built into the transmission shift knob, which is able to detect the presence of alcohol in the perspiration of the driver's palm as he or she attempts to start driving. When the alcohol-level detected is above the pre-determined threshold, the system automatically locks the transmission, immobilizing the car. A "drunk-driving" voice alert is also issued via the car navigation system.
Passenger Seat Sensor:
2) Additional alcohol odor sensors are also incorporated into the driver's and passenger seats to detect the presence of alcohol in the air inside the vehicle cabin. When alcohol is detected, the system issues both a voice alert and a message alert on the navigation system monitor.
Facial Monitoring System:
A camera is mounted on the instrument cluster facing the driver to monitor the driver's face:
The system is calibrated to monitor the driver's state of consciousness through their eyes. When the system detects signs of drowsiness, a voice and message alert is triggered via the navigation system. Additionally, a seat-belt mechanism is activated, which tightens around the driver to gain his or her immediate attention.
Driving Behavior By constantly monitoring the operational behavior of the vehicle (e.g. sensing if the vehicle is drifting out of its driving lane), the system can identify signs of inattentiveness or distraction in the driver. When the system detects such behavior, voice and message alerts are issued via the navigation system. The seat-belt alert mechanism is also activated, tightening around the driver to gain immediate attention.
This concept car was developed as an exploratory platform to showcase breakthrough technologies that could potentially be applied in future production cars, part of an ongoing program from Nissan contributing towards preventing drunk-driving.

Nissan has already launched and is developing several initiatives to help prevent drunk-driving. In June, the company introduced the "drunk-driving" message alert on its navigation system. In July, Nissan also began testing of a new on-board breathalyzer system in cooperation with several local government authorities in Japan, where an interlock mechanism will immobilize the vehicle if the driver's breath indicates the presence of alcohol above a specified level.
Nissan is taking a holistic approach towards safety that extends beyond the technology built into its vehicles. To achieve a "safe driving environment," Nissan has embarked on the Intelligent Transport System Project (ITS) in Kanagawa Prefecture - aimed at helping to reduce road accidents via the analysis of traffic data collected from on-the-road vehicles and traffic beacons. In Japan, the company's safety vision is to halve the number of traffic fatalities or serious injuries involving Nissan vehicles by 2015 compared with the level in 1995.
