New Toyota Supra may get a twin-turbo Lexus V6

We've heard endless rumors that a successor to the much loved and much missed Toyota Supra is in the works. Toyota hasn't done much to deny these conversations. On the contrary, the FT-1 concept from two years ago and the partnership with BMW have only fueled the fire. Now, talk of a new Lexus engine has led to speculation about the supposed Supra's powertrain. To be clear, this is mostly heresay. Few things have actually been confirmed, but based on what we know a few conclusions can be drawn. We know that BMW and Toyota are working on a joint product. We've seen mules testing out in the wild. In BMW guise, the possibly Austrian-built car will more than likely powered by turbocharged inline four and six-cylinder engines. Unless Toyota wants to use Bimmer power, they'll need to shoehorn one of their own under the hood. That leads us to this rumor of a twin-turbocharged V6 that will presumably power the new Lexus GS and LS. Japanese automotive publication Mag-X first reported on this engine. It was then picked up by YouWheel and Car Keys. Mag-X cites Toyota insiders and even gives an engine code, 943F. This engine allegedly will make more than 400 horsepower and more than 300 lb-ft of torque. While unconfirmed, this makes sense for Lexus. Nearly every luxury competitor has a six-cylinder engine with forced induction. While Toyota has previously had turbocharged inline-sixes, they've never produced a factory turbo V6. Every automaker is downsizing engines in an effort to meet fuel economy and emissions regulations. Toyota and Lexus will follow suit. Taking that V6 and tuning it for a performance application is a solid, if unverified, possibility. Related Video:

2016 Lexus GS F First Drive [w/video]

Performance cars used to be about horsepower and chassis tuning. Lately the question isn't so much what's under the hood, but how many buttons are on the console. We're overwhelmed with individual settings for engine response, transmission, exhaust, steering, and ride. When did these cars turn into a choose your own tuning adventure? The Lexus GS F represents an attempt to step back from this over-adjustable madness and return to more bygone sports car values. It has a special engine, unique bodywork, and a chassis tuned for high performance. There are only two settings you need to play with. The first setting is the Drive Mode Select dial on the center console, which mainly controls the response of 5.0-liter V8 engine and the shift behavior of the eight-speed automatic. The engine is the same V8 found in the RC F, making the same 467 horsepower and 389 pound-feet of torque. New this year are small balancing weights on the crankshaft pulley that cut down on internal vibration. Drive Mode Select also changes the electronic power steering, air conditioning, and stability control (you can also turn it all the way off via a separate button). The engine is the same V8 found in the RC F, making the same 467 horsepower and 389 pound-feet of torque. You will use two settings in the GS F: Eco when you want to get somewhere, Sport S+ when you want to get somewhere fast. Normal and Sport S modes offer intermediate steps you don't really need. Eco mode softens the throttle and reduces the use of air conditioning for slightly better fuel economy. It also makes the center-mounted tachometer switch into an eco-driving gauge. S+ puts everything into sport mode, including a heavier steering weight and a higher stability control threshold. While Sport S mode shifts the noon position of the tachometer to just below the horsepower peak of 7,000 rpm, S+ goes a step further and turns the rev indicator into a solid bar that grows around the edge of the display. It also adds oil and coolant temperature to the readout. And how could we fail to mention G-Force Artificial Intelligence (or grin at such an overwrought name)? That's the shift logic the transmission uses in Sport S+. It's designed to hold revs in corners and downshift during hard braking. "Our goal with F is to make a driver's car, not a drag race winner." The other button in the Lexus GS F that you need to pay attention to is next to the Drive Mode Select knob, labeled TVD for Torque Vectoring Differential.

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.
