JaguarLandRover engineers continue to achieve significant vehicle mass reductions, this time with the new generation Land Rover Discovery. Shifting to aluminum construction for the bodyshell instead of steel and complemented by an intensive light weighting program for the whole car, has yielded a remarkable 480 kg (1,058 lb) saved compared with the previous model. This exceeds even the 420kg (925 lb) reduction of the Range Rover in 2012 when it was switched to an aluminum-intensive architecture.
Reinventing the wheels: Tesla Model 3
The wheels on the forthcoming electric sports sedan direct air under the body. Tesla uses aero simulation tools from Boston-based Exa, and the computer-aided wheel design would reduce the need for expensive active aero devices, thus cutting costs.
Onroak Automotive a dévoilé ce vendredi à Spa la Ligier JS P217 qui arpentera les circuits du monde entier dès la saison 2017.
Le prototype français propulsé par le moteur V8 de chez Gibson sera éligible en FIA WEC, en ELMS, en IMSA WeatherTech SportsCar Championship ainsi qu’en Asian Le Mans Series. Le châssis de Onroak Automotive fait partie des quatre sélectionnés par l’ACO, la FIA et l’IMSA répondant au nouveau règlement de la catégorie LMP2 qui entrera en vigueur en 2017.
Moving from wind tunnel testing of physical prototypes to simulation-driven design processes can offer typical automotive OEMs more than 500% ROI (return on investment), according to research from Tufts University’s Gordon Institute for engineering management.
Platooning improves fuel economy by at least 10% and Exa simulations calculate optimum distance as 30 feet, with added potential new economy available by booking best slot in platoon.
If Tesla wants its planned electric truck to come with enough range acceptable to haulage fleets, it might need to accelerate research into platooning. Platooning is when smart trucks connect digitally to travel in close convoy, in order to improve overall fuel economy.
Infotainmentsysteme erfordern im Hinblick auf das Wärmemanagement besonderen Testaufwand. Als Alternative zu den üblichen Klimawindkanaltests könnte eine entwickelte Simulationsmethodik auf Basis der Software von Exa dienen.
“If Tesla wants its planned electric truck to come with enough range acceptable to haulage fleets, it might need to accelerate research into platooning. Platooning is when smart trucks connect digitally to travel in close convoy, in order to improve overall fuel economy.
Erstmals simuliert ein OEM zusammen mit dem Softwareanbieter Exa das Verhalten des Infotainmentsystems bei extremen Umgebungsbedingungen. So kann schon früh die am besten zu kühlende Position gefunden und das Packaging entsprechend angepasst werden.
Das heutige Infotainmentsystem ist das Gehirn eines modernen Fahrzeugs, das dem Fahrer wichtige Informationen über den Betriebszustand und das Umfeld zur Verfügung stellt. Es hilft dem Fahrer, ans gewünschte Ziel zu navigieren und dabei das Fahrzeug sicher zu bewegen. Aufgrund des hohen Kühlungsbedarfs, den die komplexe Elektronik insbesondere in heißen Klimazonen hat, erfordert dieses kritische System zusätzliche Aufmerksamkeit im Hinblick auf das Wärmemanagement.

Kevin Golsch, technical director of Exa Corporation, said the benefits of drafting in this manner have been proven. In April this year, a fleet of trucks from all of the major European manufacturers linked via Wi-Fi to take part in a Dutch-organised transcontinental drive.
Just what would a Tesla electric freight truck look like? It's a question that many in the auto industry have been asking after the latest visionary bulletin (Master Plan, Part Deux) from Tesla founder and talisman Elon Musk.
Tesla CEO Elon Musk wrote in his Master Plan, Part Deux, that future electric models from Tesla will include a full-sized truck. He promised that it would "deliver a substantial reduction in the cost of cargo transport" as well as being safer and "really fun to operate".
Ales Alajbegovic, VP Ground Transportation at EXA is in a position to have some inkling of the design that may be coming down the Tesla CV line (and unveiled as early as next year). EXA already works with Tesla to reduce aerodynamic drag on its passenger vehicles, as well as truck firms and semi-trailer makers to help reduce air drag and cut down on the substantial fuel costs.
We’ve all experienced turbulence on an airplane, but back on terra firma, those troublesome, swirling pockets of air can have just as great an impact on how a car moves along the road and how much fuel it spends. And for automakers, the ability to accurately simulate turbulence helps to create quieter, slipperier, and more fuel-efficient vehicles.
This follows the September 2015 launch of new facilities at Halewood and Elmdon near Birmingham, U.K., the start of operations for IAC Itatiaia in Brazil and a growing footprint in China: It opened its 16th location in China last October – a new manufacturing facility in Tianjin.
So, as you hurriedly raise the window while yelling at your friend to just ask when they are feeling too hot next time, you wonder, “What the heck was that noise?”
That noise is known as Helmholtz resonance, or more colloquially, “wind throb.” Putting it simply, the noise is generated in the same way you make noise by blowing across the mouth of a soda bottle.
Exa® Corporation (Nasdaq:EXA), a global innovator in simulation software for product engineering, announced the appointment of Suresh Sundaram as Senior Vice President, Products and Marketing effective today. In this role, Dr. Sundaram will report to the Chief Executive Officer, Stephen Remondi, and be responsible for the company’s product management and marketing activities.
From sports cars to sedans, drivers battle the ‘wub wub wub’; not a flat
Charles Brownstein’s annoyance with the “throbbing noise” that invades the cockpit of his Porsche 911 at high speeds became so intense that he turned to an orange juice bottle for relief.
Exa® Corporation (NASDAQ:EXA), a global innovator in simulation software for product engineering, today announced that its Chief Executive Officer, Stephen Remondi and Chief Financial Officer, Richard Gilbody are scheduled to present at the upcoming Canaccord Genuity 36th Annual Growth Conference to be held in Boston.

Challenging emissions and fuel economy targets are being set worldwide. In this exclusive Automotive World report, leading truck OEMs and suppliers provide insight into how they plan to meet these future targets.
Exa Corp., a global innovator in simulation software for product engineering, and DENSO Corp. have announced a new collaborative partnership that will transform the way carmakers have traditionally interacted with suppliers. The partnership enhances the product development process by moving key engineering and design work from automotive suppliers to a certified simulation-driven process that can be done much earlier in the development process, reducing the number of late-stage vehicle design changes.
Tesla Motors named after Nikola Tesla, an extraordinary scientist, is becoming a household name in electric cars.
The company came up with their first vehicle Tesla Roadster in 2006, followed by Model S and Model X. Model 3, was recently unveiled in March 2016 and received more than 325,000 reservations within a week.
Using simulation tools from an early phase of vehicle design can reduce time to market and eliminate the need for costly prototyping. As a result, companies that specialise in providing the software for automotive applications believe that simulation will play an increasingly important role in vehicle design as OEMs look for competitive advantages across every aspect of development.
As part of a new collaborative partnership, Exa Corporation and Denso Corporation will transform the way car makers interact with suppliers. This will be done by enhancing the product development process through moving key engineering and design work from automotive suppliers to a certified simulation-driven process that can be done much earlier in the development process, and therefore reduces the number of late-stage vehicle design changes.
