Tier 1 suppliers call GM the worst OEM to work with

Among automakers with a big US presence, General Motors is the worst to work for, according to a new survey from Tier 1 automotive suppliers, conducted by Planning Perspectives, Inc.
The Detroit-based manufacturer, which has been under fire following the ignition switch recall and its accompanying scandal, finished behind six other automakers with big US manufacturing operations. Suppliers had issues with trust and communications, as well as intellectual property protection. GM was also the least likely to allow suppliers to raise their prices in the face of unexpected increases in material cost, all of which contributed to 55 percent of suppliers saying their relationship with GM was "poor to very poor."
GM's cross-town competitors didn't fare much better. Chrysler finished in fifth place, ahead of GM and behind Dearborn-based Ford, which was passed for third place this year by Nissan. Toyota took the top marks, while Honda captured second place.

TMG's super Lexus LS Sports 650 gets track tested

The people at Toyota Motorsport GmbH have been responsible for the Japanese automaker's motorsports efforts since the 1970s, but since Toyota pulled out of Formula One after the 2009 season, the tuning shop has been developing a super sedan based on the Lexus LS called the Sports 650. Details on TMG's first road car have been scarce, but XCAR was recently invited to drive the 641-horsepower Lexus on track.
Here's what we know: the Sports 650 has enough power to sprint to 60 miles per hour in under four seconds, tops out at 199 mph, weighs over two tons and utilizes LFA brakes. Oh, and its twin-turbo V8 bellows like an AMG V8. That last part isn't surprising when considering TMG could become Toyota's in-house tuning arm - like AMG is to Mercedes-Benz. As for the bespoke body kit, fender flares and stacked exhaust pipes? They fit the car well and even remind us a bit of Lexus' other high-performance sedan, the IS F. Currently there are no plans for the Sports 650 to be made into a production car, but we doubt TMG is devoting this much effort developing the LS into a road-rocket for nothing.
Check out XCAR's video below to see the AMG-fighter wrung out on track, and then ponder what could be if TMG were let loose to fiddle with other cars in Lexus' lineup. Now that's something we could get used to!

Toyota reveals Tokyo Motor Show concepts

Toyota is getting ready for the Tokyo Motor Show later this month, and to tease us, the Japanese automaker has released photos and information about the concept vehicles it'll be bringing to the show. In all, there'll be five world premieres from Toyota (six if you split the Voxy and Noah minivan concepts), including some vehicles that'll be released in the near future, and others that need more time to incubate.
Let's get the world premieres out first. Toyota is a pioneer of gasoline-electric hybrids, but it's also pursuing hydrogen fuel cell-powered vehicles. The clearest indication of this is the FCV concept, a hydrogen-powered sedan in the same vein as the the FCV-R that will bow at the auto show. (Read more about the FCV, here.)
Other world debuts include the FV2 concept (pictured), a unique, one-seat future vehicle that emphasizes the "Fun to Drive" philosophy; the JPN TAXI concept, a next-generation taxi concept designed with Japanese hospitality in mind; and the Voxy and Noah concepts, next-generation minivans that differ most in exterior design cues and are scheduled to launch in the Japanese market in early 2014.
