Volkswagen Touareg Hybrid

Volkswagen is busy presenting a prototype of the future Touareg V6 TSI Hybrid. This car will enter production in 2010 as the world’s first hybrid SUV to have 3.5 metric ton towing capacity. Volkswagen is introducing one of the highest performance parallel hybrid systems in the world in this SUV. The German carmaker is utilising the alliance of a V6 TSI (245 kW) boosted by supercharger and an electric motor (38 kW). Up to a speed of 50 km/h, the Touareg V6 TSI Hybrid can be driven by just the electric motor. In this case, no emissions are generated.

The Touareg Hybrid prototype currently being demonstrated apparently incorporates many features of the future production vehicle. The car is powered by a new V6 TSI — a highly advanced configuration of a direct injection gasoline engine boosted by a mechanically-driven supercharger — in tandem with an electric motor. It features a newly developed 8-speed automatic transmission. The SUV is able to offer a new all-wheel drive system and up to 3.5 metric tons towing capacity.

When used in the hybrid drive, fuel consumption of less than 9.0 liters of fuel per 100 kilometers is attained. The electric motor installed between the V6 TSI and the 8-speed automatic transmission delivers a maximum power of 38 kW / 52 PS. In boosting mode — where maximum torque and power are required, the V6 TSI engine and the electric motor operate together (by kickdown or gearshift selector in “S” position). Under these conditions, a temporary maximum power of 275 kW is available with a maximum torque of 550 Nm.

Sales of hybrid vehicles slide

January 27th, 2009 by Darren Cottingham

Despite all the ‘big-ups’ for hybrid vehicles sales of battery-pack-transporters are down nearly ten percent for 2008. At the beginning of 2008, it looked like hybrids were going to have their best year ever, driven by high fuel prices and a recessive economy. That recession, however,has caused consumers to cut way back, leading to dramatic drop in fuel prices, removing much of the argument for a hybrid’s price premium. Consumers shy away from hybrids when fuel prices drop causing the issue of fuel efficiency to fall out from the limelight.

Toyota is still the hybrid sales king, with 241,000 units shifted in 2008. Honda managed to ring up 31,000 sales, and Ford came in third with nearly 20,000 vehicles sold.

Volvo’s product development unit is still hard at work, even after Ford desperately put a price tag on the brand (click here to read news item). Volvo is busy developing more environmentally-friendly vehicles capable of meeting tough new  emissions regulations on the horizon, the Swedish automaker has been working on some new highly-efficient vehicles.

In addition to the DRIVe trio of ultra-efficient diesel-powered models, Volvo is working on an all-new micro-hybrid model. Set to join the lineup in 2011, the vehicle will be available in gas or diesel powered form, and a manual or automatic transmission. Fuel-saving technology will include a start-stop system plus brake-energy regeneration to cut consumption by nearly 5 percent. We’ll see a full hybrid (with the ability to run on electric power only) in 2012 with the D5 diesel engine. A plug-in electric is also expected to follow in the future.

Mercedes-Benz S 400 BlueHYBRID – petrol/electric luxury

September 18th, 2008 by Darren Cottingham

Mercedes-Benz is launching its first passenger car model equipped with a hybrid drive system in mid-2009 – the S 400 BlueHYBRID. With a modified 3.5-litre, 220kW (299hp) V6 petrol engine and a compact hybrid module producing an extra 15kW (20hp) it’ll be one of the world’s most economical luxury saloons with a spark-ignition engine. The NEDC combined fuel consumption is 7.9 litres per 100 kilometres, which beats the V8-powered Lexus LS600hL’s 9.3l/100km. It also makes for the world’s lowest CO2 emissions in this vehicle and performance class – just 190 grams per kilometre. These exemplary figures go hand in hand with assured performance. The new S 400 BlueHYBRID is the first series-production model to be equipped with a particularly efficient lithium-ion battery specially developed for automotive use.

It is based on the S 350, and features an extensively modified drive train. This encompasses a further development of the 3.5-litre V6 petrol engine, an additional magneto-electric motor, the 7G-TRONIC seven-speed automatic transmission specially configured for the hybrid module, the necessary operating and control electronics, the transformer and a high-voltage lithium-ion battery.

The compact hybrid module is a disc-shaped electric motor that also acts as a starter and generator. The system offers a double benefit, as it both helps to save fuel and increases driving enjoyment. This is partly due to the booster effect of the electric motor, as it powerfully backs up the petrol engine with a maximum additional torque of 160 newton metres during the high-consumption acceleration phase, giving a total of 385Nm of available torque.

The hybrid module also has a comfortable start/stop function, which switches the engine off when the vehicle is at a standstill – for example at traffic lights. When it’s time to move off again, the electric motor almost imperceptibly restarts the main power unit. This likewise makes a contribution to fuel economy and environmental protection: because the engine restarts first time, and practically instantly, emissions are also minimised during the starting phase.

When the vehicle is braked the electric motor acts as a generator, and is able to recover braking energy by a process known as recuperation. The electric motor supplements the braking effect of the petrol engine and the wheel brakes to deliver a smoothly progressive braking action. The recuperated energy is stored in a compact yet highly efficient lithium-ion battery in the engine compartment, and made available when required. This complex system is managed by a high-performance control unit, which is likewise located in the engine compartment.

Major advantages of the lithium ion battery over conventional nickel/metal hydride batteries include a higher energy density and better electrical efficiency, together with more compact dimensions and a lower weight.

The S 400 BlueHYBRID accelerates from zero to 100 km/h in 7.2 seconds, and reaches an electronically governed top speed of 250 km/h. The S 400 BlueHYBRID betters the NEDC fuel consumption of the conventionally powered S 350 by up to 2.2 litres per 100 kilometres. CO2 emissions are reduced by 21 percent.

Prius fighter: Honda shows its new Insight

September 5th, 2008 by Darren Cottingham


Honda will reveal a concept version of its new small hybrid vehicle, to be named Insight, at the 2008 Paris International Auto Show, October 2. The new Insight Concept shares styling cues with the Honda FCX Clarity fuel cell vehicle and will provide an early look at the highly-anticipated five-passenger hybrid vehicle.

We don’t have a release date for New Zealand, but it will be on sale in the U.S. next spring most probably significantly below the price of current hybrids like the Toyota Prius.

The Insight Concept defines a new stage in the evolution of hybrid technology by utilising a more cost-efficient version of Honda’s Integrated Motor Assistâ„¢ (IMAâ„¢) hybrid technology. Evoking the innovative styling cues first seen in the FCX Clarity, the Insight Concept is designed with a low centre of gravity and a generous five-passenger cabin. Aerodynamic design assists its fuel efficiency, and by all accounts it should be reasonably roomy and practical with five doors, a hatchback and a folding rear seat.

Numerous technologies, including a function to assist customers in achieving more fuel efficient driving habits, will be applied to achieve a further improvement in real world fuel efficiency. Along with the Civic Hybrid, the new vehicle will be produced at an expanded hybrid vehicle production line at the Suzuka factory in Japan.

The Insight is expected to have annual global sales of 200,000 units per year – approximately 100,000 in North America. Following the launch of the new Insight, Honda also plans to introduce another unique sporty hybrid vehicle based on the CR-Z, first shown at the 2007 Tokyo Motor Show. All together, Honda’s global sales of hybrids should increase to approximately 500,000 units a year, or more than 10 percent of its total worldwide annual automobile sales.

The original Honda Insight was introduced in December 1999 as America’s first gas-electric hybrid car. The first vehicle to break the 70-mpg (3.36l/100km) fuel economy barrier, Insight was designed from the ground up to demonstrate the ultimate potential for fuel-economy in a two-seater subcompact automobile.

A leader in the development of cleaner, more fuel-efficient mobility products, Honda introduced the first low-emission gasoline vehicles; America’s first gas-electric hybrid car and the world’s first EPA-certified hydrogen fuel-cell vehicle, the FCX. In 2007, Honda was named “greenest automaker” by the Union of Concerned Scientists for the fourth straight time.

Peugeot RC concept to be named at Paris could see production

August 21st, 2008 by Darren Cottingham


The ‘RC¦’ whose full name will be revealed at the Paris Motor Show, is a hybrid concept car created by Peugeot’s stylists and engineers.

It is a ‘GT’ coupe which provides the missing link between the RC and concept cars revealed in 2002 and the 908 RC, one of the stars of the 2006 Paris Motor Show. It’s a working laboratory of many future ideas and brings together numerous stylistic, engineering and technological ideas all in a single vehicle.

The ‘RC¦’ is also an accessible and versatile car, with four doors, four seats and highly innovative hybrid architecture.

Its aim: a very high level of efficiency both in terms of performance (with its potential maximum power output of 313 bhp) and minimal impact on the environment (CO2 emissions of 109 g/km in the combined cycle or ZERO in electric mode).

It is an exciting, eco-efficient vehicle which has all the characteristics that also ensure great driving enjoyment; a synthesis of ideas which demonstrates that respect for the environment and driving pleasure can be compatible.

Chery shows off ‘mild’ hybrids in Olympic bid

August 8th, 2008 by Darren Cottingham


As a part of the transportation arrangements for the Beijing Olympics, a 50-unit fleet of hybrid vehicles co-developed with Ricardo is being provided by Chery Automobile Company Ltd. Known as the “Olympics Green Messengers”, these vehicles are some of China’s first hybrid vehicles and will go into full production in the months following the games.

With its expertise in hybrid electric vehicles and its wide-ranging skills in systems integration and vehicle control and electronics, Ricardo was a natural choice of engineering partner for Chery when the Chinese automaker decided to develop its first hybrid products. Two new vehicles, both based on its existing A5 sedan model, were identified by Chery. The first is a stop-start hybrid based on a 12-volt Belt Starter-Generator (BSG) linked to 1.6 litre gasoline engine, itself linked to a 5-speed manual transmission. The second is a more comprehensive mild-hybrid based on the same baseline vehicle but instead equipped with a 1.3 litre gasoline engine and a 12 kW crankshaft-mounted 151-volt Integrated Starter-Generator (ISG). These technologies have been configured to be capable of providing significant fuel savings through the use of advanced powertrain control and energy management strategies.

Key Ricardo responsibilities for the BSG programme included full architecture, sub-system and components requirements definition, hybrid control unit design, vehicle and communications interface development, system design — including detailed thermal analysis — and powertrain control strategy for safety and efficient operation. The focus of the engineering programme and the efficiency of the development programme were such that the first prototype vehicle was run with production-intent hardware and complete with hybrid strategy and application software, just ten months from programme start. The final fuel economy results are no less impressive: in tests over the ECE Urban drive cycle, the BSG vehicle achieves approximately a 7 per cent improvement in fuel consumption over the baseline product, and it is expected that the improvement will be greater than 10 per cent in real-world urban driving.

For the more complex ISG product, Ricardo carried full system design authority including specification and integration of the ISG system, high-voltage battery pack and battery management system, and developed an integrated hybrid control unit that incorporates the motor drive power electronics, DC to DC converter, and hybrid supervisory and safety functions into one compact package. The safety-critical application strategies and software were defined, engineered and validated including extensive vehicle and hardware-in-the-loop testing. With its comprehensive mild-hybrid functionality, the ISG-equipped sedan provides a significant increase in performance over the equivalent baseline A5 vehicle fitted with a 1.3 litre engine; peak power and torque of the ISG-equipped vehicle are comparable with that of a larger 1.6 litre engine.  Final production calibration and testing of the vehicle systems are still taking place, but the fuel consumption improvement over the NEDC cycle is expected to approach 15 per cent compared to the 1.6 litre benchmark vehicle. In addition, the system enables engine restart within 200 milliseconds, thus allowing stop-start functionality to be included in the hybrid control strategy.

The new BSG and ISG powertrain equipped A5 models of Chery Automobile Co. Ltd underscore the position of this fast-growing Chinese automaker as one of China’s automotive technology leaders. Engineered to exacting European emissions requirements, these new vehicles are due to enter full production shortly and will be available for both domestic Chinese and export markets.
