Regulatory requirements for emissions reduction are increasing the importance of vehicle aerodynamics. A further reduction in drag is key: it’s thought that most OEMs are targeting a drag coefficient (Cd) of 0.2, down from a best of around 0.24 currently, as achieved by Tesla with its all-electric Model S.
The eight-time winners of the American Solar Challenge, the University of Michigan (U-M), have unveiled the car they hope will propel them to a global win at the World Solar Challenge across Australia in October.
As an array of commercial vehicle manufacturers begin to focus on how to comply with the Phase 2 greenhouse gas (GHG) reduction mandates, more “virtual testing” of truck and trailer designs is expected to be deployed to reach the required fuel economy goals within the rules.
Carmakers spend a fortune on prototypes for new models. Such mock-ups are not seen by outsiders, unless photos dribble out on a motoring blog, but can each cost as much as $1m.
Now, however, these secret test bed vehicles could be on the endangered list as manufacturers shift towards digital simulation methods.
ANN ARBOR—With a car that seats the driver so far to the right they had to design an elbow bulge into the chassis, the nation's top-ranked solar car team today unveiled the vehicle it will race across Australia in the Bridgestone World Solar Challenge.
OEMs have always relied on wind tunnels to validate aerodynamic characteristics but now the benefits of virtual testing are increasingly hard to ignore.
Der französische Rennfahrzeugentwickler Onroak Automotive hat für den jüngsten Wurf seines LMP3-Rennwagens Simulationssoftware von Exa verwendet. In nur drei Monaten konnten die Ingenieure den Designprozess für die Aerodynamik und Kühlung abbilden.
With the unprecedented demands on today’s vehicle engineering organizations, automakers face a daunting challenge to reach their next targets for aerodynamics drag using traditional tools and methods. Trial-and-error development using wind tunnel testing achieved a coefficient of drag of 0.3. Introducing digital simulation to sequentially improve designs brought CD down to 0.24 for today’s best performing cars. But most companies have the next target set to 0.2.
BOSTON - The emergence of autonomous cars will present many interesting technical challenges, not the least vehicle aerodynamics. Due to the nature of the problem, many of the aerodynamics challenges will have to be addressed using simulations.
The new LMP3 class is beginning to take shape, with several chassis manufacturers getting in on the action. The latest is Ligier along with simulation softwarecompany Exa Corporation, which introduced its new JS P3 LMP3-class racer this week at Le Mans. Ligier adds its name to the roster of Ginetta and LAS Motorsport, who are among the manufacturers already committed to LMP3.
(Motorsport-Total.com) - Ginetta bekommt bald weitere Konkurrenz auf dem Markt für Fahrzeugeder neuen LMP3-Klasse. Zwei Tage nach der Vorstellung eines entsprechenden Projekts des Münchener Unternehmens Adess, hat nun Onroak ein fertig produziertes Auto in Le Mans präsentiert. Der neue Ligier JS P3, der unter anderem mit Hilfe der amerikanischen CFD-Spezialisten Exa entworfen wurde, soll in der kommenden Woche in ein intensives Testprogramm gehen.
The latest Ligier-branded sports prototype, the Ligier JS P3, has been revealed today at Le Mans.
Part of the ongoing partnership between Onroak Automotive and Ligier, the Ligier JS P3 will be eligible for the ACO’s cost-cutting LMP3 category.
Onroak Automotive president Jacques Nicolet and Ligier founder Guy Ligier were on hand to publicly present the first chassis at Circuit de la Sarthe.
Today, on the 11th of June 2015, in the heart of the paddock of the 24 Hours of Le Mans, Guy Ligier, founder of the Ligier brand, and Jacques Nicolet, President of Onroak Automotive, have unveiled the Ligier JS P3. This new LM P3 sport-prototype designed by the French manufacturer’s Design Office, doesn’t hide its kinship with the Ligier JS P2 and immediately seduced the wide audience of journalists and guests.
Exa® Corporation (Nasdaq:EXA), the leading innovator of simulation software for product design and engineering, and its customer in France, Onroak Automotive, unveiled an all-new LMP3 sports prototype racing car today (Thursday) at Le Mans.
Exa Corporation and Onroak Automotive, unveiled an all-new LMP3 sports prototype racing car at Le Mans. Ligier JS P3, the new LIGIER has been conceived to compete in the Automobile Club de l’Ouest’s new Le Mans Prototype 3 (LMP3) category which gives teams and drivers a new entry point into Le Mans-style endurance racing.The Ligier JS P3 was designed using Exa’s PowerFLOW simulation software to optimize its aerodynamics, as well as maximize cabin comfort and cool both the engine and brakes with new levels of efficiency.
With only one day left until the action finally gets underway at Circuit de la Sarthe in Le Mans, some manufacturers are looking to the future and take the opportunity to launch "innovative" LMP3 race cars. Of course, we're talking about Exa Works and Onroak Automotive.
Exa(R) Corporation of Burlington, MA and French client Onroak Automotive, unveiled their all-new LMP3 sports prototype racing car today at Le Mans. Dubber Ligier JS P3, the new LIGIER has been developed to compete in the Automobile Club de l'Ouest's new Le Mans Prototype 3 (LMP3) category which gives teams and drivers a new entry point into Le Mans-style endurance racing.
In February 2014, President Obama called for new heavy duty (HD) truck emissions standards. A draft of the proposed Phase II greenhouse gas (GHG) and fuel economy rule is expected to be published in June 2015. After a period of consultation, the final Phase II rule will be published in 2016.
Automotive World spoke to key truck industry stakeholders to gauge their views on the longer-term implications of a tightening of the current GHG standards.
Steve Remondi co-founded software simulation firm Exa in 1992 with a Massachusetts Institute of Technology professor on the premise that the historical way of building, testing and designing cars is flawed, notably when it comes to achieving superior aerodynamics, fluid flow and thermal efficiencies.
Exa® Corporation (Nasdaq:EXA) announces its newest release, PowerFLOW 5.1, offering up to a 300% speed up for complex transient cabin comfort simulations — allowing vehicle manufacturers an accurate, robust, and practical method of studying exceedingly complex thermal engineering problems.
Exa Corporation , the leading innovator of simulation software for product design and engineering, today launched an upgrade to its results generation, analysis and reporting program, PowerINSIGHT®. This completely revised software allows users to optimize product performance early in the development process by automating the analysis and sharing of simulation results — fostering improved collaboration between engineering and design teams.
One of the big draws of the 2014 Paris Motor Show was the unveiling of the Jaguar XE. Critically acclaimed, the compact executive sedan took centre stage on the Jaguar stand, lauded for it's design, fuel efficiency and its potential for the Jaguar brand
Compared to the current NEDC test, which was developed over 30 years ago, the importance of aerodynamics will rise with the new WLTP proposed for implementation from 2017. The WLTP will put more emphasis on real-world higher-speed driving in order to improve fuel economy. For truly accurate and insightful results, not all the work can be undertaken in a wind tunnel. Instead, aerodynamic modelling, like for the Jaguar XE, can be achieved entirely through simulation-driven design with CFD software tools from Exa Corporation.
