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.

Toyota announces new, more efficient powertrains for 60 percent of its vehicles by 2021

In the face of increasingly strict standards on fuel economy and CO2 emissions, Toyota announced today that it's introducing a new hybrid system, a new 2.5-liter direct-injection inline four-cylinder engine, and two new transmissions – an eight- and a 10-speed. The development of all of these components will be based around the Toyota New Global Architecture, or TNGA. Development of the systems has moved forward and the new powertrains will find their way into vehicles starting next year. TNGA, like Mazda's Skyactiv technology, is a complete design philosophy that focuses on more than just a clean or efficient engine. The first vehicle to deploy the TNGA platform was the current, fourth-generation Prius. With TNGA, Toyota focused on improving handling, ride, and braking performance. The new powertrains are meant to compliment this new platform by being both engaging to drive and fuel efficient. Since TNGA can be adapted for front-, rear-, or all-wheel-drive layouts, it's capable of underpinning a number of potential products. Toyota is arguably the leader in hybrid technology, and taking lessons learned in the development of the current Prius, the automaker has developed the new Toyota Hybrid System II, or THS-II, for rear-wheel-drive applications. Performance has improved versus the outgoing model, and Toyota says efficiency, especially at high speeds, has been improved. In addition, the system's use in plug-in vehicles has been improved. For the first time, the electric motor will be able to provide direct driving power, whereas before it simply acted as a generator. The new, naturally aspirated 2.5-liter four-cylinder, like the THS-II, has been designed around the TNGA platform. Most notably, the thermal efficiency of the engine has been improved. This means a higher output and improved exhaust and cooling. The new engine, which works in both traditional and hybrid applications, will proliferate through the Toyota and Lexus lineup. Toyota's two new automatic transmissions, like the new engines, are based on the TNGA system. That means a lighter and more compact design relative to similar transmissions. The 10-speed is intended for rear-wheel-drive Lexus products like the GS and LS. The tuning has been adjusted to improve response and smooth out shifts, though it's impossible to say how much it's been improved without getting behind the wheel.

Next Lexus LX 600 and LX 750h specs reportedly leaked

Specs for the next Lexus LX appear to have been leaked to a Japanese blog. The flagship luxury SUV will reportedly come in two flavors, and offer greater differentiation from its Land Cruiser cousin than ever before. One of those variants is, for the first time, a hybrid version. The Japanese site Creative Trend reported on the 300-series Land Cruiser specs before most, and aside from some small discrepancies in horsepower and torque numbers, was surprisingly accurate. They even called the existence of a GR Sport performance trim level. Now, they've turned their focus to the LX. As translated by Lexus Enthusiast, the entry spec will be called the LX 600, and will likely feature the Land Cruiser's 3.5-liter twin-turbo V6. That should be good for an identical 415 horsepower and 480 pound-feet of torque. Creative Trend adds that in the Middle East, the entry model will be called LX 500d, implying it'll be equipped with the Land Cruiser's turbodiesel 3.3-liter V6 generating 309 horses and 516 lb-ft.  The flagship model, however, is said to be the LX 750h, which adds a hybrid-electric system to the 3.5-liter petrol V6. Together, they'd make a potent 480 horsepower and 642 lb-ft of torque. This powertrain is not available on the Land Cruiser. In addition, the LX will have a more luxurious and high-tech interior, with a rumored version of the new Lexus Interface that appeared on the new Lexus NX. However, whereas the NX sports a 14-inch version of the screen, the LX will reportedly receive a 17-inch version. Incidentally, it seems the LX may have already been seen in the NX's reveal video, albeit under a white cloth. Additionally, we have it on good authority from friends in Japanese media that both the Land Cruiser and Lexus LX will, in Japan, feature a fingerprint recognition system on the engine start button. The off-roaders routinely top the stolen vehicles list in Japan, with about 5 out of every 100 registered vehicles stolen every year and rates increasing. Most of them end up being shipped overseas where Land Cruisers and Lexus LXes are seen as tough status symbols. Lastly, the report says Lexus Japan will start accepting pre-orders in September, with the LX itself debuting in December. While we are sadly not privy to the new Land Cruiser, it's likely the Lexus LX will arrive stateside. Whether these specs carry over remains to be seen.
