Cadillac ELR suspension and steering systems in detail [VIDEO]

Drivers expect hybrid and electric cars to have advanced battery and drive systems that make smart use of energy. Cadillac’s upcoming electrified luxury coupe, the 2014 ELR, is designed to exceed those expectations by also providing engaging, responsive driving dynamics enabled by advanced suspension and steering systems.

The technologies include front HiPer Strut suspension, rear compound crank with Watt’s link suspension, a premium ZF electric power steering system and ZF-Sachs continuous damping control.

“ELR’s methodical use of advanced suspension and steering technologies front and rear has resulted in the quiet cabin, agile handling and superior ride that Cadillac customers have come to expect,” said Chris Thomason, ELR vehicle chief engineer. “ELR will redefine for many people what the electric car driving experience is all about. Not only does it make smart use of energy, it makes energy-efficient driving fun and luxurious.”

ELR’s industry-leading Extended-Range Electric Vehicle (EREV) propulsion system delivers 295 lb-ft (400 Nm) of instantly available torque. In driver-selectable Sport mode, the reconfigured accelerator pedal provides quicker torque application and more sensitive feedback through altered suspension and steering settings. ELR also offers Tour, Hold and Mountain driving modes.

With so much torque available, engineers relied on a HiPer Strut front suspension to eliminate torque steer and increase front axle grip while cornering due to optimized tire contact with the road. The HiPer Strut also contributes to ELR’s precise, communicative and linear steering feel, and reduces unwanted steering system disturbances over rough roads and bumps for an overall smoother ride.

In its rear suspension, ELR uses a Watt’s link design to center the car’s rear axle during turns to provide a more balanced driving experience. When cornering, the Watt’s link provides greater lateral stiffness that results in more positive vehicle response to steering inputs and helps keep the rear suspension aligned with the front suspension. When the ELR is traveling on a straightaway, the Watt’s link allows the suspension to travel up and down freely to make the ride more comfortable.

ELR’s premium electric power steering system is designed to provide excellent feedback while saving fuel. The rack-mounted, dual-pinion system – one for steering and one for power assist – consumes energy only when the vehicle is actively steered. A combined electric motor and sensing unit monitors steering angle and delivers appropriate assist to the steering gear at all times, correcting for crowned road surfaces and cross-winds. This helps reduce driver fatigue.

In driver-selectable Sport mode, ELR’s steering gear provides increased on-center sharpness and steering sensitivity for dynamic steering. In the more relaxed Tour mode, it allows precise control with less driver steering efforts.

ELR’s continuous damping control monitors sensors throughout the vehicle, vehicle speed and the driver’s input, and adjusts damping accordingly for each 20-inch wheel every two milliseconds to maintain optimal vehicle ride control over varying road surfaces and profiles. This reduces and controls vehicle roll, pitch and vertical motions for a flat “sky-hook” ride performance, and instantly responds to cornering maneuvers by automatically adjusting the dampers to a firmer level for superior handling and stability. When driving on smooth roads, the dampers are automatically adjusted to the softest setting to provide increased isolation and ride comfort.

An isolated four-mount front cradle contributes to the ELR’s overall quietness, noise and vibration performance, and ride-and-handling dynamics. Specifically tuned mounts are tailored to the engine’s inherent torque axis, decreasing the transfer of vibration and noise into the cabin.

Now in its final months of pre-launch engineering testing, the ELR is slated to reach showrooms in the U.S. by early 2014. ELR is the first car by a full-line luxury brand to offer Extended Range Electric Vehicle technology. The EREV propulsion technology provides full driving range exceeding 300 miles (480 km), combining pure electric driving and an efficient, range-extending generator.

Four time World Solar Challenge winners unveil – Nuna 7

The team that won the World Solar Challenge four times consecutively between 2001 and 2007 have unveiled their latest solar racer.

The Nuna7 solar-powered vehicle – which features pioneering pore-filling technology – will take part in the competition in Australia in October, representing the fourth time that the Nuon Solar Team from the Technical University in Delft and Sikkens paint experts from the company's Automotive and Aerospace Coatings business have worked together.

This year, however, will be the first time that the Nuna has used the new composite pinhole filler Aerowave 2501, which has already been used on commercial aircraft.

"When the carbon fiber shell of the Nuna is manufactured, the process creates pinholes that must be filled with putty and then sanded, often multiple times," explained John Grevers, AkzoNobel's Technical Coordinator for Benelux and Sikkens project leader for the Nuna.

"Our water-based pinhole filler replaces much of the putty and doesn't require sanding, because it can be easily wiped away. Which means it also adds less weight to the car than traditional fillers."

As well as the new pinhole filler, the Nuna 7 also features an aerodynamically advanced Sikkens coatings system designed to reduce wind drag and cut down on preparation time. Products used include Colorbuild Plus, Autocryl Plus LV, and Autoclear LV Superior.

"AkzoNobel is helping us a lot in terms of making sure that we have the best possible aerodynamics thanks to the finish they provide," said Leslie Nooteboom, the Delft team's Public Relations manager. "We feel that the company is playing a very important role in our chances of winning the race in Australia."

Added Grevers: "It has been a valuable experience for us to develop coatings that not only provide advanced aerodynamics, but can also perform well under the extreme temperatures of solar car racing. And it’s always good to work with students because they bring a fresh vision."

The team hopes to go one better than 2011, when the Nuna 6 finished second in the 11th World Solar Challenge. The biennial event – which aims to promote research on solar-powered cars – attracts teams from across the globe. The 2013 race will be staged from October 6 to 13.

Toyota Sells Three Millionth Prius

Toyota Prius has passed a significant milestone with the sale of the three-millionth car. The total includes more than 1.3 million deliveries in North America, a similar number in Japan, 260,000 in Europe and almost 80,000 in the rest of the world.

Australians have bought more than 18,300 Prius since its launch in this country in October 2001. Prius was first launched in Japan late in 1997 and is now sold in 60 countries and regions. The second generation followed in 2003 and the third generation in 2009.

Annual sales exceeded 100,000 for the first time in 2004 and cumulative sales reached one million in 2008, with the two millionth being sold in September 2010. Since then, Toyota has expanded Prius into a family of vehicles. Including the Prius c city car and Prius v seven-seater, cumulative global sales of the Prius family have now reached 3.8 million.

Total global sales of all Toyota and Lexus hybrids exceed 5.3 million units.

In 2012, the company sold more than one million hybrid vehicles in a calendar year for the first time. From the first to third generation, Toyota Motor Corporation (TMC) reduced the cost of the hybrid system by two-thirds and improved fuel efficiency. In addition, TMC applied for 1,261 patents relating to the third-generation Prius, achieving progress worthy of the Prius name (derived from a Latin word meaning "to go before").

Since the development of the first-generation Prius, TMC has positioned hybrid technology as a core technology required for the development of various types of environment-friendly vehicles. TMC has also placed emphasis on the development and production of core components such as motors, inverters, batteries and electronic control units, giving rise to substantial investment. TMC will continue to conduct R&D and invest in facilities for the development of hybrid and other cutting-edge technologies and achieve sustainable growth by deploying these technologies across the globe.

In the fiscal year ending March 2014, TMC expects to spend 790 billion yen (A$8.6 billion)* - a year on year increase of 11 per cent - on environmental technology development, as well as on strengthening new platform and major component development. In the same period, TMC also plans to make consolidated capital expenditure investments of 910 billion yen (up seven per cent year on year).
