Automotive World - US Truck Industry Prepares for GHG Phase II: Automotive Megatrends -subscriber only access

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.

Exa Helps Clients Gain Powerful Design Insights from Big Data

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.

CFD Optimization for Efficient Aerodynamics and More Beautiful Styling

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.

Automotive News - Designers Use New Tricks, and the Wind Tunnel

Ford's big, bruising Atlas Concept pickup displayed at the 2013 Detroit auto show showcased advanced aerodynamic features. 

Its active wheel shutters closed at highway speeds to seal gaps between spokes, reducing wind turbulence around the wheels and tires. And its front air dam raised and lowered at different speeds to improve underbody airflow.

GOEVGO - See a Tesla Model S rendered in a ‘digital wind tunnel’ (w/videos)

The Tesla Model S electric car has one of the lowest drag coefficients of any vehicle currently in production, which helps it make the most of each battery charge.

Part of what allowed engineers pull that off is a rendering program called PowerFLOW, made by Exa Corporation. According to Teslarati, the software essentially creates a “digital wind tunnel” that allows engineers to see airflow and make adjustments more easily.

Design Engineering - Exa Corporation Announces ExaCLOUD

Exa Corporation a provider of simulation software, has released the ExaCLOUD, providing customers access to the company’s full suite of simulation software through a Web interface.

This new product, according to the company, offers a scalable, high-performance computing environment. It also provides a way for engineering teams and companies to handle outstanding simulation needs without investing in infrastructure.

Hometown Life - Livonia Company Shows off Aerodynamic Simulations

When it comes to building aerodynamic vehicles, most car companies have needed to build several models to test in wind tunnels and other conditions. But using technology from one company located in Livonia may make those test models less needed.

Exa, a company headquartered in Burlington, Mass., and which has an office in Livonia, demonstrated its cloud-based technology this week at the North American International Auto Show at Cobo Center in Detroit.

Embraer Adopts Exa PowerFLOW to Study Noise Sources Earlier in the Design Process

Exa® Corporation, a global innovator of fluids simulation (CAE/CFD) solutions for product engineering, today announced that Embraer, the world's third largest commercial aircraft company, is significantly expanding its usage of Exa's PowerFLOW® software. PowerFLOW will be used to help improve the aerodynamic and aeroacoustic performance of its new products. 

Automotive News Europe - New CO2 Rules May Benefit Car Design

Proposed changes to how fuel economy and emissions are measured could mean the end of useful-but-ugly side mirrors and other design changes on cars.

Steve Remondi, CEO of U.S.-based aerodynamic modeling software firm Exa, told me that EU and the U.S safety regulations have been adapted so that side mirrors can be replaced by cameras that feed the information to screens inside the car.

Reuters - Renault Aims to Reclaim Lost Ground with Minivan Turned SUV

The minivan is dead, long live the SUVan. Renault has revamped the elderly Espace people carrier as a crossover sport utility vehicle as it seeks to relive the marque's past glories.

Illustrating a market shift to more rugged-looking vehicles, the fifth Espace - smaller than its predecessors but still gargantuan by European standards - made its debut at the Paris auto show on Thursday, 30 years after the first model was unleashed on European consumers who hadn't yet realized they wanted one.


Aerodynamically Optimized with Exa PowerFLOW, Mitsubishi Motors' Electric Racecar Wins Pikes Peak

Exa® Japan Inc., a subsidiary of Exa Corporation (Nasdaq:EXA), a simulation solutions provider for product engineering, announced that Exa PowerFLOW® was chosen for the aerodynamic development of Mitsubishi Motor Corporation's electric racecar, the MiEV Evolution III. Mitsubishi's new racecar won its premiere motorsports event at the 2014 Pikes Peak International Hill Climb, held in Colorado, USA.

Exa PowerDELTA 2.1 Release Enables Optimization and Design Space Exploration

Exa® Corporation (Nasdaq:EXA), a global innovator of fluids simulation solutions for product engineering, today announced the release of PowerDELTA® 2.1. Simulation-based design has created a strong demand for automated design studies and optimization and this latest release offers innovative new features that enable automated generation of the many design variations needed with this powerful technique.
