Since the recent Tata-funded Jaguar Land Rover (JLR) rebirth, Jaguar has had its chance to shine with XE, XF and F-Pace; Range Rover had its starring role with both Range Rover and Range Rover Sport SUVs; and now its Land Rover's turn with the all-new much light, tech laden and more luxurious Discovery.
The 2017 Land Rover Discovery is being hailed for its sleek design and what’s under the hood, but its major accomplishments—shedding 1,000 pounds and becoming more aerodynamic—wouldn’t have been possible without serious horsepower in the form of virtual testing and simulation.

If Tesla wants its planned electric truck to come with enough range that is 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.

At the 2016 Paris Motor Show, Jaguar Land Rover (JLR) showcased its new Discovery – a seven-seater SUV that will go on sale in spring 2017. It includes a number of striking design choices, like the lightweight aluminium construction that saves 480kg and is a key contributor in reducing CO2 emissions by 22% compared to the previous generation.

This year’s Paris Motor Show was full of superfast concept cars and innovative technology, but the Land Rover Discovery was still one of the most important cars unveiled in the French capital last week. Although it looks pretty conventional on the outside, it was developed using sophisticated simulation technology that you’d usually associate with F1.
In the past, cars were built almost by a process of trial and error. You built a prototype, then tested it to find out what worked and what didn't. Nowadays, much of this work is done by computers.
Theo Leggett has been talking to Stephen Remondi, chief executive of Exa Corporation, to see how 3D simulations are being used by designers to refine their work in the virtual world before a single car panel has been built in the real one.
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.
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.
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.

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.
"Second quarter revenue was within our guidance range, reflecting the predictability of our licensing model. In addition, profitability exceeded our guidance range as we continue to realize the leverage in our operating model," said Stephen Remondi, President and Chief Executive Officer of Exa. "We believe that our focus on license revenue, as we continue the conversion of project-based customers to ExaCLOUD-based recurring license customers, will drive stronger year-over-year revenue growth in the second half of the year.
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.
