Lexus looking for performance with 600-hp LF-LC?

Lexus has been keeping development of the production version of its LF-LC concept tightly under wraps. Last we heard, that halo GT car had received the green light for production, but that was over a year ago. Since then, things have been pretty silent. Finally though, fresh rumors about the luxury coupe are starting to leak out, pointing toward the model's powertrain lineup.
According to unnamed sources speaking to Motor Trend, the production LF-LC will eventually sport three very intriguing engine options. The base model will reportedly use a naturally aspirated V8 providing around 450 horsepower - very similar specs to the upcoming RC F. The next step up will allegedly be the upcoming hybrid powertrain shared between BMW and Toyota pumping things up to around 500 hp. Finally, a top-of-the-heap F version will use a twin-turbocharged version of the RC F's 5.0-liter V8 to bring output to 600 hp. The insiders even claim that the hybrid and the twin-turbo V8 could find their way into other Lexus products like the LS and possibly even a more beastly RC.
None of this speculation sounds too outlandish. Lexus could get more capacity out of the RC F's tuned V8 by shoving it into other models, and rumors are flying about performance cars spawned from BMW and Toyota's partnership. Given Lexus' recent embrace of turbocharging, even the twin-turbo V8 doesn't seem too dubious. That said, with no hard facts to back up the rumormill, we'll have to keep waiting to see what the LF-LC shows up with.

BMW-Toyota partnership to spawn hybrid supercar

BMW and Toyota inked a partnership some time ago to develop green technology, and while we were excited by the idea of a reborn Supra with BMW's carbon fiber reinforced plastic slashing the curb weight or an ultra-efficient, hybridized 1 Series, the joint efforts have been rather limited. That's set to change, though, according to a report from Australia.
Motoring reports that the partners have come to terms on a sports car. And not just any sports car, but a lightweight, hybridized model, with a six-figure price tag. Lending a bit of street cred to that idea is the site's claim that Toyota is currently carrying out durability testing on the BMW i8. According to the site, the new model will slot into the spot left by the Lexus LFA, although based on the language used, it's unclear if this is the Tokyo-bound vehicle we mentioned several months ago.
Details on this potential car are limited, although Motoring claims it will use a Toyota hybrid system mated up to a BMW gas engine - likely the 4.4-liter, twin-turbo V8 found in the M5 and M6. That sounds pretty amazing to us, but we'd still advise taking this with a grain of salt. What would you like to see out of a joint-venture supercar from Toyota and BMW? Let us know in Comments, and have your say on the prospects of a hybridized, twin-turbocharged V8.

NHTSA may investigate new Toyota unintended acceleration case

After paying a $1.2-billion settlement to the US government last year, Toyota largely put the unintended acceleration recall behind it. Although, there were still some civil lawsuits to handle. A new case where the owner of a 2009 Lexus ES350 is petitioning the National Highway Traffic Safety Administration to open another analysis could draw the issue back to the forefront. Investigators are still deciding whether to research these claims further, though. According to this petition, the owner's wife was driving the ES350 in February 2015. While pulling into a parking space, the sedan allegedly surged forward, and there was a low-speed accident. The claim asserts there are at least two other similar cases in NHTSA's database: one in a 2009 Camry in 2009 and another in a 2010 Corolla in 2014. Specifically, this person wants an "investigation into low-speed surging in different models of Toyota automobiles in which the car starts accelerating and the engine RPM increases even when the accelerator pedal is not depressed," according to the agency. NHTSA will do further research into this person's claim and will decide whether to conduct a full investigation into the alleged issue. This won't be the first reappraisal of unintended acceleration in Toyotas by the agency in recent months, though. Between September 2014 and May 2015, NHTSA evaluated a similar petition with allegations covering 2006-2010 Corollas, and the government body decided to deny that one because the problem couldn't be replicated.

The petition was prompted by a February 2015 crash involving a model year (MY) 2009 Lexus ES350, which allegedly surged as the petitioner's wife was pulling into a parking spot.
