Frankfurt motor show: Toyota Auris HSD Full Hybrid
TOYOTA UNVEILS AURIS HSD FULL HYBRID* CONCEPT
Frankfurt motor show debut for precursor to Toyota's first full hybrid mainstream European production model
KEY POINTS
* Concept previews new Auris HSD Full Hybrid, Toyota's first full hybrid mainstream model in Europe
* World debut at the Frankfurt motor show
* Hybrid Synergy Drive powertrain, shared with latest generation Prius
* Sub-100g/km CO2 emissions, class-leading combined cycle fuel consumption and 0-62mph acceleration in around 10 seconds
* Detailed exterior styling changes to improve aerodynamic performance
* Extension of on-board solar power technology
* Auris HSD Full Hybrid production model to be built at TMUK's Burnaston factory
* Sales scheduled to start during second half of 2010
* 'Full Hybrid' means the car can be driven on petrol engine alone, electric motor alone or combination of both. Not all hybrids can do this.
The new Auris HSD Full Hybrid Concept, presented publicly for the first time at the Frankfurt motor show, marks a significant milestone in Toyota's plan to equip its mainstream European models with full hybrid technology. Toyota is committed to making the environmental benefits of its Hybrid Synergy Drive (HSD) accessible to a wider customer base and it is on track to offer a hybrid version of every model in its range by the early 2020s.
A five door hatchback is the best selling type of car in Europe and consequently the installation of HSD in Auris is the logical first step in deploying full hybrid technology across Toyota's entire European model line-up.
By introducing the Auris HSD Full Hybrid Concept, Toyota also aims to shift customer perceptions of hybrid technology. The obvious advantages are exceptional fuel efficiency and low CO2 emissions, but customers will also experience smooth and sophisticated driving unlike any other family hatchback, thanks to the everyday usability, comfort and quietness of the Toyota full hybrid powertrain.
The Auris HSD Full Hybrid will be built by Toyota Motor Manufacturing UK (TMUK) at the Burnaston factory, near Derby, with sales scheduled to start during the second half of 2010.
The news that Europe's first hybrid production model will be built in the UK has been welcomed by the British Government. Business Secretary Lord Mandelson said: "I'm delighted Toyota has chosen the UK to build its first hybrid vehicle in Europe. When I visited the Burnaston plant in July, I saw for myself the energy and commitment of Toyota and its workers. The unveiling of the new car at the Frankfurt Motor Show brings the vision of making the UK the best place in the world to develop low carbon vehicles a step closer. I look forward to seeing the cars roll off the line next year."
Exterior design
The design of the Auris HSD Full Hybrid Concept reflects the installation of a full hybrid powertrain in a mainstream package. Subtle changes have been made to Auris's styling to improve aerodynamic efficiency and blue hybrid badging identifies the car as a member of Toyota's full hybrid fleet.
The front end is designed to optimise airflow and so help maximise fuel efficiency. The front and rear bumper corners have flat surfaces, a feature that not only accentuates the car's wide and solid stance, but also smoothes the flow of air over the vehicle's flanks, minimising turbulence and drag.
The ride height is lower by 20mm compared to the conventional Auris, and underbody panels and a rear diffuser have been fitted to smooth and control airflow beneath the car. The bespoke 18-inch alloy wheels are designed to cut air turbulence in the wheel arches and are shod with low rolling resistance tyres. A larger, more efficient rear spoiler is also fitted. These aerodynamic elements target a drag coefficient of 0.28.
Interior design
The cabin has a number of special features that are linked to the car's full hybrid status.
The seats and upper dashboard are finished in blue Gaucholino leather with light blue accent stitching. To complement the exterior body colour, the centre console and side air vents have a tactile, pearl white finish.
The instrument cluster has hybrid blue illumination, with a design that combines high technology with easy-to-read displays. Alloy pedals reinforce the performance dimension of HSD technology and the steering wheel has a flat bottom section for easy driver access and better legroom.
Sequenced entry and exit lighting is provided, including puddle lights integrated in the door mirrors and ambient illumination of the footwells and headlining. Thick carpeting raises the on-board comfort and refinement levels and also contributes to a marked improvement in cabin quietness.
Refined driving experience
Using the same powertrain as the latest generation Prius, the Auris HSD Full Hybrid Concept is the first mainstream model in Europe to benefit from Toyota's refined, smooth and quiet Hybrid Synergy Drive.
The car will accelerate from nought to 62mph in around 10 seconds, while returning class-leading combined cycle fuel economy and sub-100g/km CO2 emissions. It offers four driving modes, three of which can be selected on-demand by the driver: ECO mode maximises hybrid system efficiency and fuel economy; Power mode boosts performance; and EV mode – a feature only available with a full hybrid system – allows for ultra-quiet running on electric motor power alone for up to 1.25 miles (2km) at speeds up to 31mph, with zero fuel consumption and zero CO2 and particulates (PM) emissions.
Building on the inherent quietness of HSD, particular attention has been paid to further NVH reduction measures to achieve a calm, quiet cabin environment at all speeds. Road and engine noise have been suppressed by comprehensive use of soundproofing materials, and full thickness glazing and an acoustic windscreen reduce wind noise at cruising speeds.
Environmentally efficient technology
Using technology that was first brought to the market in the latest generation Prius, the Auris HSD Full Hybrid Concept marks a further development of solar powered ventilation, with solar panels covering the entire roof.
Similar technology is used inside the cabin, with solar panels on top of the dashboard that generate sufficient energy to recharge mobile phones or portable music plays mounted in purpose-designed charging trays. In the future, Toyota aims to advance this technology to provide solar powered recharging of the hybrid battery.
Further energy-saving measures include the use of LED technology for the front and rear lights.

Lamborghini Reventon Roadster - First Details and Images
Lamborghini Reventon Roadster – ultimately open
Designer piece with uncompromising performance
Lamborghini presents the ultimate driving machine among open-top two-seaters – the Reventón Roadster is a sports car of breathtaking fascination, menacing power and uncompromising performance. The 6.5 liter twelve-cylinder generates 493 kW (670 PS), catapulting the Roadster from 0 to 100 Km/h (0 to 62 mph) in 3.4 seconds and onwards to a top speed of 330 KM/h (205 mph). The open-top Reventón is not only one of the fastest, but also one of the most exclusive cars in the world – Lamborghini has limited the series.
The Lamborghini Reventon is not destined to remain a one-off. Less than 20 Lamborghini friends and collectors will be able to own this extraordinary car and, naturally, enjoy the incomparable pleasure of driving it.
Each Reventón Roadster will be sold for 1.1 Million Euro (without taxes). Deliveries will begin October 2009.
"The Reventón is the most extreme car in the history of the brand," comments Stephan Winkelmann, President and CEO of Automobili Lamborghini S.p.A. "The new Roadster adds an extra emotional component to our combined technological expertise – it unites superior performance with the sensual fascination of open-top driving." The Reventón Coupé was presented at the 2007 IAA in Frankfurt and was sold out immediately.
Open-top sports cars are a tradition at Lamborghini that stretches back over 40 years. In 1968, the company from Sant'Agata Bolognese built a Miura without a fixed roof as a one-off. The Diablo Roadster appeared in 1995 with its targa roof anchored to the engine cover.
Sculpture with extreme dynamics
All Lamborghinis are created with an avantgarde approach to design; a fast-moving technical sculpture. The Reventón Roadster is derived from the same creative thinking as the Coupé. Its designers found their inspiration in aviation – the aggressive wedge shape evokes images of fighter jets.
The powerful arrowhead form at the front, the mighty air intakes pulled way forward, the broad side skirts, the upwards opening scissor doors and the rear end with its menacing edges – the Roadster is clad in a design of maximum functionality and spectacular clarity. Details set stylish accents, such as headlamps featuring bi-xenon units with LEDs forming the daytime running lights and indicators. The rear lamps are also equipped with LEDs.
Like the Coupé, the Reventón Roadster measures 4700 mm (185 in.) long. It has a wheelbase of 2665 mm (105 in.) and is 2058 mm (81 in.) wide and 1132 mm (45 in.) high. The driver and passenger seating positions are low and sporty, separated by a substantial central tunnel.
Behind the two seats are two hidden pop-up bars that deploy upwards in just a few hundredths of a second in the event of an imminent rollover. A fixed, horizontal wing-shaped member behind the seats bears the third brake light. The design of the Roadster's long back is also quite distinct from that of the Coupé. The engine bonnet is virtually horizontal and a total of four windows made from glass provide a view of the mighty V12 in all its technical elegance.
Stiff bodyshell base
The base bodyshell of the Reventón is already so stiff that the Roadster requires only minimal reinforcement. It has a dry weight of only 1690 Kg (3,725 lbs.), just 25 Kg, (55 lbs.) more than the Coupé.
Like the Coupé, the cell of the Roadster is made from high-strength steel profile and carbon components joined with specialist adhesive and rivets. The bodyshell is made almost entirely from carbon fiber elements, with sheet steel used only for the outer door skins.
Exclusive grey paintwork
A unique paint finish completes the razor sharp design language of the Lamborghini Reventon Roadster. For this exclusive special edition, designers have created a new shade of matt grey called Reventón Grey. As for the Reventón Coupé, which is a slightly different shade of grey, this is a matt paint finish that, in the sunlight, displays an unexpected impression of depth thanks to its special metal particles.
The wheels of the Reventón Roadster also incorporate the interplay of matt and glossy elements. The five spokes of the rims each bear a Y-form, and on each spoke are mounted small crescent-shaped wings made from matte carbon. These provide not only an unusual visual impact, but also a turbine effect that further improves cooling of the mighty ceramic brake discs.
Aircraft-style displays
The interior of the Reventón Roadster conveys the same powerful design as the exterior. The cockpit is structured with technical clarity, the interfaces arranged for functionality. Like a modern aircraft, the open two-seater no longer has classic analogue instrumentation – instead, information is delivered via two transreflective and one transmissive liquid-crystal displays.
The driver can switch between two modes at the touch of a button – one digital view with illuminated bars and one level with classic round dials, albeit with changing color graphics. Centrally located at the top of the display is the G-force meter. It represents the intensity of the forces acting on the Reventón Roadster under acceleration, braking and heavy cornering; the same format used in Formula 1.
The instruments are mounted in a casing machined from solid aluminum which is housed in a carbon fiber dashboard. The interior displays uncompromisingly clean craftsmanship and features a host of carbon fiber applications – e.g. on the center tunnel – aluminum, Alcantara and leather. The central panels and the seat cushions are perforated, with precision stitching gracing their outer edges.
Lamborghini has equipped the Reventón Roadster with full options.
An icon of engine design
The twelve-cylinder engine that powers the Reventón Roadster is a Lamborghini icon – and the technical feature that defines the character of the car. It is one of the world's most powerful naturally-aspirated engines. With a compression ratio of 11 : 1 and a displacement of 6496 cc (396.41 in3,) it generates 670 PS (493 kW) at 8,000 rpm. Its maximum torque of 660 Nm (487 lb-ft) kicks in at 6,000 rpm.
The V12 engine is a masterpiece of Italian engineering. Two chains drive its four camshafts that, in turn, operate the 48 valves. Together with the three-phase adjustable intake manifold, the variable valve timing delivers a meaty torque build-up. Dry sump lubrication ensures that the hi-tech power unit has a constant supply of oil, even under heavy lateral acceleration. The absence of the oil sump means a low mounting position – benefitting the car's outstanding handling characteristics.
The V12 catapults the Reventón Roadster from 0 to 100 Km/h (0 to 62 mph) in 3.4 seconds and onwards to a top speed of 330 Km/h (205 mph). It reacts with the eagerness of a racing engine to input from the right foot, revving to 8,000 rpm and beyond, and performing a symphony that sends shudders along the spine. The deep booming bass, the powerful mid-range and the exultant horn section play music that, once heard, can never be forgotten.
All-wheel drive for maximum traction
In classic Lamborghini style, the aluminum engine is mounted longitudinally in front of the rear axle, with the transmission ahead of it beneath the center tunnel. This layout results in 58 percent of the overall weight being borne by the rear wheels – ideal for a powerful sports car.
This layout accommodates the Viscous Traction permanent all-wheel drive. Under normal conditions, it sends the vast majority of the driving force to the rear wheels. Should they begin to spin, the central viscous coupling sends up to 35 percent of the power via an additional shaft to the front axle. Limited-slip differentials are located there and at the rear axle with 25 and 45 percent lock respectively.
Lamborghini introduced the all-wheel drive principle with the Diablo. The reason back then was just as clear as it is today - four driven wheels grip far better than two, and the more powerful the engine, the greater the impact of this fundamental law of physics.
Also standard on the Reventón Roadster is the e.gear automated six-speed sequential manual transmission. The driver controls the gear shift, which is activated hydraulically via two steering wheel paddles. In addition to the "Normal" mode, the system offers a "Corsa" and a "low adherence" mode. The driver just has to keep his foot to the floor - the rest is handled by e.gear.
Running gear layout from motorsport
The Reventón Roadster keeps the extreme power of its engine in check with a running gear layout derived directly from motorsport. Each wheel boasts double wishbone suspension, with one spring strut on each side of the front axle and two each at the rear. The front end of the car can be raised by 40 mm (about 1.6 in.) to protect the underside of the vehicle over potholes or on steep entrances into underground garages.
The open two-seater runs on 18-inch wheels. The front tires measure 245/35, while the rears are 335/30. Dedicated air channels in the bodyshell cool the four wheel brakes. Carbon-fiber ceramic discs are standard – they have an extremely lightweight construction, operate with virtually no fade, are corrosion-free and achieve the highest service life. Each disc has a diameter of 380 mm (~15 in.) and is gripped by six-piston calipers.
As fast as the open two-seater may be, its road manners are impeccable. Its performance limits are extremely high, yet effortless to control. And, on exiting a bend, all four wheels stick tenaciously to the asphalt. The permanent all-wheel drive dovetails the car firmly with the road, delivering decisive benefits in traction and stability.
High-performance aerodynamics
A further distinctive characteristic of the Reventón Roadster is its calm directional stability even at extremely high speeds – a feature that also turns fast highway stretches into sheer joy. Alongside the bodyshell design and the smooth underbody, which culminates in a powerfully formed diffuser, the rear spoiler carries responsibility for downforce. It deploys from the rear edge at about 130 Km/h (80 mph) and adopts an even steeper angle as of about 220 Km/h (136 mph). The entire aerodynamic concept – around and through the car – is radically laid out for performance.
State-of the-art development techniques
Lamborghini used state-of-the-art, highly networked processes to bring the Reventón Roadster to life. The design, CAD work and model making that took place in the Centro Stile, which opened in 2004, were accompanied continuously by specialists and test engineers from the Research & Development Department.
The Design Department is directly linked to the neighbouring Ufficio Tecnico, ensuring rapid implementation of ideas. Lamborghini's capabilities also include the independent development of the complete electronic platform. This incorporates all control units – including those for the V12 and the innovative cockpit displays.
All units of the Reventón Roadster are being built on the Sant'Agata Bolognese production line, with perfect craftsmanship and to the highest levels of quality.

2009 Frankfurt Auto Show - 2010 Audi A4 3.0 TDI Clean Diesel Quattro
The Audi A4 3.0 TDI clean diesel quattro – Highly efficient and extremely clean
* The world's cleanest diesel technology now also in the A4
* Midsize sedan consumes only 6.7 liters per 100 km (35.11 US mpg)
* Powerful engine with 240 hp and 500 Nm (368.78 lb-ft) of torque
Using the world's cleanest diesel technology, the 3.0 TDI clean diesel already meets the Euro 6 emission standard not scheduled to enter into force until 2014. Having debuted in the Audi Q7, the innovative engine is now coming to the A4. The powerful TDI is not only extremely clean, it is also highly efficient, using only 6.7 liters of fuel per 100 km (35.11 US mpg) in the EU cycle.
The technology package of the Audi A4 3.0 TDI clean diesel quattro comprises the engine itself and the highly efficient exhaust gas after-treatment system. A new common rail injection system that develops pressures of up to 2,000 bar, innovative combustion chamber pressure sensors and an ultra-high-performance exhaust gas recirculation system ensure highly efficient combustion which produces minimal raw emissions.
A novel DeNOX catalytic converter at the end of the exhaust system reduces nitrogen oxides. Just upstream of it, a pump injects an aqueous additive named AdBlue into the hot exhaust flow, where this solution decomposes into ammonia, which splits the nitrogen oxides into nitrogen and water. The tank is large enough that the driver never has to refill it. This is done instead by the Audi dealership during scheduled maintenance.
Using the world's cleanest diesel technology, the Audi A4 3.0 TDI clean diesel quattro meets the Euro 6 emission standard announced for 2014. It is also very fuel-efficient, averaging only 6.7 liters (Avant: 6.8 liters) of fuel per 100 km (35.11 and 34.59 US mpg).
The innovative V6 TDI engine makes the A4 a powerful performer, needing only 6.2 seconds (Avant: 6.3 seconds) to go from zero to 100 km/h (62.14 mph). Top speed is electronically governed to 250 km/h (155.34 mph). The combination with the six-speed tiptronic and quattro permanent all-wheel drive ensures a high degree of comfort and superior traction.
