Corvette ZR1 chief engineer Tadge Juechter recently sat down to participate in a live chat on GMNext to answer questions about Chevy’s new supercar, with topics ranging from fuel-economy to production numbers.

GM hasn’t run its fuel economy test yet, but in a previous release from the General, it expects the ZR1 to be the most fuel-efficient 600-hp vehicle on the market. Juechter did say that the ZR1, “will be somewhat less [fuel-efficient] than a Z06,” which is currently rated at 15/24 by the EPA, “and we expect a small gas-guzzler tax [on the ZR1].” Production will be limited to 2,000 units each year for worldwide consumption and pricing will be revealed sometime this month.

Juechter went on to say that ZR1 accessories wouldn’t be made available for lesser Corvette models, so buyers won’t be able to option up for carbon-ceramic brakes or Michelin tires on their Z06s. When asked if engineers considered all-wheel-drive for the ZR1, he emphasized that making the vehicle as lightweight as possible was a top priority and that an AWD system “would have added too much mass.” And on the topic of price gouging by dealers, Juechter said only one thing: “We’re strongly encouraging dealers to charge MSRP.” Good luck on that.

Earlier today we reported that Tesla Motors appaears to have discovered a solution for the transmission troubles that have delayed production of the Roadster so far. The California-based all-electric automaker has now confirmed to Inside Line that it will begin production of its first batch of roadsters on March 17, though they’ll be fitted with temporary two-speed single-speed transmissions and retrofitted later with what the company calls DriveTrain 1.5. Production of the EV Roadster, however, will take a while to gear up: initially the company will build just one vehicle per week, getting into the full swing of 40 cars per week by the end of the year.
Observers also recently noticed a banner reading “Coming Spring 2008″ that was hanging in front of Tesla’s dealership in Los Angeles has disappeared. With Tesla Motors being so much in the spotlight, some speculated that the Roadsters arrival had been delayed again. The company’s spokesman, Joe Powers, has revealed that the banner merely blew off and hasn’t been re-hung yet. It just goes to show how interested and impatient people are for the Tesla Roadster to finally arrive.

Alright, we get it. SED actually is not the wave of the future for televisions, but OLED most probably is. At present, we’ve got Sony, Toshiba, Samsung and LG Display (among others) all vying for your future dollars, and since competition in the HDTV space is so grand for consumers, we won’t be kvetching too much about yet another entrant. DigiTimes has it that Matsushita (parent company of Panasonic) is looking to begin production of OLED displays “in the future.” That’s it. No juicy clues as to when, no inside information about panel sizes — nothing. Just enough to tease you and leave you in a state of panic for the foreseeable future.

Oh yeah, we’re mildly excited that LG Display should be able to start cranking out product from its 8G LCD plant earlier than expected, but the real kicker here is the outfit’s outlook on OLED. Merely two days after hearing that Samsung was hoping to dish out affordable medium-to-large OLED displays in 2009 / 2010, we’re now getting word that LG Display is looking to offer up a 32-incher the year after. And we’re talking “volume production,” no less. Makes holding off on that XEL-1 that much easier, doesn’t it? Nah, we didn’t really think so.

Autoweek and Fourtitude were able to enjoy some seat time in the Audi R8 V12 TDI LeMans concept before its official unveiling in Geneva last week. Their drive was short (about an hour with a 50 mph speed limit imposed by Audi’s boffins), but their time at the airport adjacent to Sebring International Raceway has made an impression.

The crimson beast we saw in Geneva was the same concept that was displayed in Detroit, simply sporting a new paint job, but spending quality time with the R8 V12 TDI revealed a few interesting tidbits about the concept. First, the firewall behind the driver and passenger had to be extended by some six-inches to accommodate the oilburner and although claimed torque output is somewhere in the 737 lb.-ft. range, the few journos asked to take part only got to experience 442 lb.-ft. of twist – a good thing considering that the transmission mated to the engine is an A4 case with modified internals.

While the performance was impressive, the short gearing and shorter redline (not disclosed) seemed to make all that grunt superfluous in first and second, but Audi is expecting the R8 V12 TDI to return around 24 mpg and meet the 2014 Euro 6 emissions standards if, and when, it goes on sale.

While the Autoweek piece only provided the “50/50″ quote in the title, the Fourtitude article is far more entertaining and informative — well worth a read.
