Gazoo heads to the N"urburgring with Lexus LFA Code X

You'd be forgiven for thinking just because the Lexus LFA has ended its production run (it's been over a year now) that Toyota would have ceased its development. You'd be forgiven, but Gazoo Racing is here to tell you you'd still be wrong.
One of Toyota's many works racing teams, Gazoo is returning to the 24-hour endurance race at the Nürburgring this year with a trio of entries. One is based on the Toyota GT86 (which we know as the Scion FR-S), and one is essentially the same LFA that it's entered in years past. But the third vehicle is dubbed Code X.
It's also based on the LFA, but its 4.8-liter V10 engine has been bored out to 5.3 liters, raising its output to untold levels. It's got a full carbon-fiber chassis and a range of other enhancements that Gazoo isn't telling us about just yet, but they should turn the LFA Code X from a road-going supercar beyond a racecar and into a rolling research lab. Considering that Gazoo has been racing at the 'Ring since 2007 and fielding versions of the LFA there since 2008, it'll be interesting to see how the Code X version fares.

Toyota recalls 337,000 RAV4s and HS250h models for tie rod failure

UPDATE: The post has been updated with additional information from NHTSA. The Basics: Toyota is recalling 337,000 2006-2011 model year Toyota RAV4 crossovers built between October 31, 2005 and September 7, 2010 as well as 2010 model year Lexus HS250h cars built between July 6, 2009 and August 26, 2010. The Problem: When either an affected RAV4 or HS250h is given an alignment and the tie rod adjustment nut on the rear control arm isn't tightened properly, the threads on the tie rod can start to rust. If this happens, the nut may break off and throw off the alignment drastically and suddenly. This isn't a case of the car simply pulling to one side, either. This would seriously upset the balance of the car and could cause the driver to lose control and crash. This is also the third time these vehicles have been recalled for the same issue. Injuries/Deaths: It's unknown if this control arm issue has resulted in any injuries or deaths. Autoblog reached out to Toyota for more information, but a company representative told us that the company isn't able to discuss injuries or deaths caused by this issue (if any) at this time. Based on information from NHTSA documents, it does not appear that any crashes, injuries or deaths have been attributed to the defect addressed in the current recall. The Fix: The dealer will completely replace the rear suspension assemblies at no cost to the owner. The tie rods and nuts will also be coated in epoxy to prevent future rusting from occurring. According to Car and Driver, the previous recalls involved tightening nuts, coating decent tie rods in epoxy and completely replacing rusted ones. The car magazine reports that further complaints were filed and the company is now replacing all components regardless of condition. If you own one: Toyota will notify owners of affected cars by mail. Owners can also check whether their cars are affected by entering the VIN at safercar.gov/vin. Owners with questions can also reach Toyota customer service at 1-800-331-4331 or Lexus customer service at 1-800-255-3987.

Toyota R&D shows off free piston engine linear generator for future EVs

We often hear how an electric vehicle powertrain architecture allows vehicle designers much more freedom than a traditional ICE powertrain does. With differently shaped battery modules and small electric motors, there are lots of way to put the pieces together. With today's plug-in hybrid technology, engineers still need to put a decent-sized ICE somewhere, but new technology from Toyota could free up the gas-electric vehicle designers of the future. Presented at the recent SAE World Congress in Detroit, the idea from Toyota Central R&D Labs Inc. and involves what is called a Free Piston Engine Linear Generator (FPEG). Think of it as a sort of one-cylinder, two-stroke mini-engine that can work either as a generator (thank to magnets and a linear coil) or to directly drive a vehicle. The current prototype is a 10-kW unit that Toyota say would provide enough power to get a B- or C-segment electric vehicle up to highway speeds (75 miles per hour) when paired up to offer 20 kW. Pairing the FPEGs is also important to minimize vibrations. One system tested by Toyota had a 42 percent thermal efficiency, but the engineers are working to improve the overall efficiency even further. You can watch an animated video of the piston in action here (click on "Outline") and see the SAE papers here and here. More technical details are available at Green Car Congress.
