Exa recently worked with Laydon Composites on a trailer skirt solution that explored which design would provide optimum results. The result of extensive simulation was a 9.3% improvement in fuel economy, and achieving U.S. EPA SmartWay Elite status without a boat tail. (pages 32-33)
BURLINGTON, Mass. and YOKOHAMA, Japan, Sept. 1, 2015 (GLOBE NEWSWIRE) -- Exa Corporation (Nasdaq:EXA), a global innovator of simulation software for product engineering, recently announced its customer, Mitsubishi Motors Corporation's (MMC), revealed PowerFLOW® helped them achieve a remarkable 25 percent downforce improvement for its record-breaking electric racecar, the MiEV Evolution III.
If you’ve ever submitted a batch job to a remote computer across a building or across the country, you’ve worked with a variation of cloud computing. Shared hardware has made sense for more than 50 years and it still does; we have moved well past the why and onto exploring the how, but sometimes the “how” can seem dull. Is the decision now more like choosing between cable or dish TV? Are cloud resources just repackaging or is there really value added?
There is more pressure than ever on heavy-truck engineers to find and create significant improvements in fuel economy and reduce tailpipe greenhouse gas (GHG) emissions. This is being driven primarily by two factors. First, customers are looking for ways to improve their business model by reducing fuel consumption. Diesel fuel prices in the past few years have been volatile, ranging from $2.931/gal (Sept. 6, 2010) up to $4.159 (Feb. 25, 2013) and back down to $2.561 (Aug. 24, 2015), according to U.S.
Is this the first sports car to be designed in software like a PCB or chip?
The Ligier JS P3 sports prototype racing car was designed using simulation software to optimise its aerodynamics an for thermal design of the engine and brakes.
US-based Exa is the EDA company behind the PowerFLOW simulation software.
The software is used by many major passenger-car manufacturers around the world, but French sports car maker Onroak Automotive has taken this to a new level with its simulation of the design of the Ligier JS P3 racer.
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.
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.
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.
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.
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.
(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.
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.
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 , 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.
