The raceway inSonomatoday unveiled a Sustainable Performance Ranking Metric that should aid consumers when purchasing a new vehicle.

The unveiling of the metric was part of a news-filled day at the 2nd annual Accelerating Sustainable Performance Summit.

The summit, which explores prospects for sustainable automotive development and performance, was attended by 200 people from the business, motor sports, engineering, research and media communities.

The metric is a collaboration between the raceway and DominicanUniversityof California’s Green MBA Program. The metric, which is a beta-version, boasts a new rating system for vehicles that combines the factors most closely associated with both sustainability AND performance.

“We had a terrific lineup for our second ASPSummit, and it was a great event,” said Steve Page, raceway president and general manager. “We really moved our effort in a much more substantive and practical direction this year and we look forward to the nextSummitin 2013.”

Factors taken into account in establishing the metric included miles per gallon, emissions, horsepower, torque and power/weight ratio.

The long-term goal is to establish a simple automobile ranking system that demonstrates which vehicles optimize both sustainability AND performance. The hope is that this metric stimulates dialogue and inspires other potential partners to work with the raceway andDominicanUniversity on creating a national standard.

Some of the top performers in the metric included:

  • Ford Mustang (sedans/coupes, under $60,000 and under $30,000)
  • Toyota Highlander Hybrid (SUVs/trucks, under $60,000)
  • Ford Edge (SUVs/trucks, under $30,000)
  • Chevrolet Volt Plug-In Hybrid (hatchback/wagons, under $60,000)
  • Toyota Prius Hybrid (hatchback/wagons, under $30,000)

The metric has undergone preliminary vetting in both the industry and academic communities and is based on a listing of the top 100 selling consumer vehicles, as well as popular hybrid and alternative-fuel models.

The metric is an attempt to begin dialogue on a final metric that can be used as the national standard. The goal is to demonstrate that you do not have to sacrifice performance for sustainability.

“The vision of the Sustainable Performance metric is to create a new standard in vehicle excellence that values both sustainability and performance and to empower consumers to choose vehicles that balance sustainability and performance,” said Joey Shepp, Sustainable Programs Director atDominicanUniversityofCalifornia. “It is also to incentivize automotive manufacturers to optimize sustainable performance technologies."

The day also included KleenSpeed establishing the initial track record for electric vehicles. Its KleenSpeed EVX-11 toured the 12-turn, 2.52-mile road course in 1 minute, 35.99 seconds (93.75 mph). The EVX-11 took first place in the Electric Vehicle Prototype Time Trials in 2009,  2010 and 2011 and can run in excess of 100 mph.

The summit also featured a panel discussion on the State of Sustainable Racing, as well as on-track demonstrations by a variety of high-performance sustainable vehicles, including Fisker. Yokohama Tire Corporation also had a demonstration of their orange-oil technology using two vehicles fitted with the company’s orange-oil infused tires: the 150kW (201 hp and 220 N-m torque) electric-powered AC Propulsion eBox Scion xB fitted with the Yokohama AVID Ascend® and a Porsche 911 GT3 Cup race car with the Yokohama ADVAN® ENV-R2™ race slicks. The ENV-R2 is the official spec tire of the 2012 IMSA GT3 Cup Challenge by Yokohama and GTC Class of the ALMS (American Le Mans Series).

Partners on the program include Amyris, Panasonic, PG&E, Safety-Kleen,Yokohama, Fuel 21, KleenSpeed andDominicanUniversity’s Green MBA program.
