Audi twists e-tron 3319 lb-ft torque rating

When introduced at the Frankfurt Motor Show in September, Audi boasted its all-electric e-tron was fitted with four electric motors producing "230 kW (313 hp) and 4,500 Nm (3,319.03 lb-ft) of torque." While the e-tron's styling may have raised a few eyebrows, we were notably moved by the quoted torque figure - especially when we considered that the twin-turbocharged Mercedes-Benz SL65 AMG, one of the most powerful vehicles on the road, makes 738 lb-ft in comparison. We were stupefied by the number, and it set off more than a few debates among our group, but Audi made no attempt to clarify...

The team at Automobile Magazine, initially duped like everyone else, has recognized that Audi was quoting torque measured at the wheels, not at the output shaft - the industry standard. Measuring torque at the wheels takes the multiplication effect of the transmission and final drive gears into account. The resulting figures are generally ten-fold of what they would be at the crank (meaning cars like a 3.6-liter Chevrolet Malibu packs a similar 3,115 lb-ft of torque). Audi's e-tron torque figures are not exactly dishonest, but they are using a completely different evaluation without making mention of it in the press release. Long story short, Automobile estimates the e-tron makes about 252 lb-ft of torque. That is a bit less than the Tesla Roadster's 273 lb-ft.

LA 2009: Audi e-tron, orange you terribly sad it was repainted

We weren't exactly electrified by Audi's e-tron concept when it debuted at the Frankfurt Motor Show in blazing red paint this past September, but we did like the color. So, when the e-tron reappeared at the LA Auto Show this week wearing orange... bummer.

As a refresh, the e-tron concept uses four electric motors with a combined output of 313 horsepower (and a mind-boggling 3,319 lb-ft of torque) to move its 3,527-pound mass to 62 mph in 4.8 seconds. More impressive is its rolling acceleration from 37-75 mph in just 4.1 seconds. The top speed is electronically-limited to 124 mph. According to Audi, we'll see a production version in 2012.

STUDY: Cash for Clunkers helped Japanese way more than Detroit 3

While there is no question that Obama's Cash-for-Clunkers program accelerated vehicle sales this summer, a new report by the University of Michigan's Transportation Research Institute shows the big winners were from Japan, not Detroit.

According to the study, nearly 85 percent of the trade-ins were from General Motors, Ford, and Chrysler, yet they only sold 39 percent of the new cars moved off the lots. On the other hand, eight percent of the trade-ins came from Toyota, Honda, and Nissan, manufacturers who accounted for 41 percent of new car purchases.

While these numbers may be justified by the large quantity of inefficient domestic trucks and SUVs that were deemed clunkers, customer loyalty also seems to have taken a big shift. About 68 percent of owners who traded in Toyota, Honda, or Nissan vehicles replaced them with another from one of those Japanese brands, while only 43 percent of consumers who traded in Detroit steel purchased another General Motors, Ford, or Chrysler product. The program cost the U.S. taxpayers about $3 billion.

Follow-up: Toyota may not produce hybrid Yaris after all

2009 Toyota Yaris - Click above for high-res image gallery

A Toyota insider is countering yesterday's report that the automaker is planning a Yaris-based hybrid to be built in France. Such a vehicle would be unnecessary, according to the unnamed source.

Today's Toyota Yaris is already a fuel miser. The European variant is currently quipped with a 1.33-liter dual VVT-i engine with start-stop technology allowing the compact runabout to earn an impressive 55.4 mpg (European) combined fuel economy (in the States, we get a 1.5-liter Yaris that is rated at 29/36 in EPA testing). While dropping a hybrid powerplant into a larger vehicle pays back significantly, the gains realized by building a hybrid Yaris would be negligible.

Down the road, it may be a different story as battery technology (one limiting factor) is improving quickly. The advent of lithium ion batteries will boost the case for compact and subcompact hybrid vehicles as the bantam-weight cars benefit from the lighter and more compact power sources.

REPORT: Tata Nano passes European crash testing

The Tata Nano, the diminutive Indian four-door econobox rumored to eventually arrive in U.S. showrooms, has reportedly passed current European impact testing. According to Autocar, the offset front and side impact tests took place at the MIRA test center last week under supervision by an inspector from Britain's Vehicle Certification Authority. A spokesperson for Tata said the company is "delighted but not surprised" with the results, as the car had already been tested in India.

Sold only in its homeland right now, Tata seems determined to expand its passenger vehicle business to Europe and North America. With that in mind, the automaker is working to upgrade the Nano to ensure the Lilliputian meets "Westernized" crash standards, including the European NCAP tests, and our own NHTSA requirements.
