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:

Japan could consolidate to three automakers by 2020

Sergio Marchionne might see his dream of big mergers in the auto industry become a reality, and an analyst thinks Japan is a likely place for consolidation to happen. Takaki Nakanishi from Jefferies Group LLC tells Bloomberg the country's car market could combine to just three or fewer major players by 2020, from seven today. "To have one or two carmakers in a country is not only natural, but also helpful to their competitiveness," Nakanishi told Bloomberg. "Japan has just too many and the resources have been too spread out. It's a natural trend to consolidate and reduce some of the wasted resources." Nakanishi's argument echoes Marchionne's reasons to push for a merger between FCA and General Motors. Automakers spend billions on research and development, but their competitors also invest money to create the same solutions. Consolidating could conceivably put that R&D money into new avenues. "In today's global marketplace, it is increasingly difficult for automakers to compete in lower volume segments like sports cars, hydrogen fuel cells, or electrified vehicles on their own," Ed Kim, vice president of Industry Analysis at AutoPacific, told Autoblog. Even without mergers, these are the areas where Japanese automakers already have partners for development. Kim cited examples like Toyota and Subaru's work on the BRZ and FR-S and its collaboration with BMW on a forthcoming sports car. Honda and GM have also reportedly deepened their cooperation on green car tech. After Toyota's recent buyout of previous partner Daihatsu, Nakanishi agrees with rumors that the automotive giant could next pursue Suzuki. He sees them like a courting couple. "For Suzuki, it's like they're just starting to exchange diaries and have yet to hold hands. When Toyota's starts to hold 5 percent of Suzuki's shares, this will be like finally touching fingertips," Nakanishi told Bloomberg. "I absolutely do believe that we are not finished seeing consolidation in Japan," Kim told Autoblog. Rising development costs to meet tougher emissions regulations make it hard for minor players in the market to remain competitive. "The smaller automakers like Suzuki, Mazda, and Mitsubishi are challenged to make it on their own in the global marketplace. Consolidation for them may be inevitable." Related Video:

Next Toyota Prius may get optional all-wheel drive

We've been hearing rumors about the next generation of the Toyota Prius for the last couple of years on a pretty regular basis. From the expectation of lithium-ion battery packs with more capacity for electric-only miles to wireless charging and more emotional styling, there's been no shortage of talking points for the car that's expected to see its first light of day at the very end of 2015 (we hope). But one thing we've yet to hear about, until now that is, is all-wheel drive. According to a report from Automotive News, Koei Saga, senior managing officer in charge of powertrain development of the Prius, said in an interview last week, "I think we will possibly do [all-wheel drive]" for the car's next generation. There isn't any further indication on how the AWD system would work, but we'd put our money on something similar, at least in principle, to the E-Four system that just debuted on the 2015 Lexus NX 300h, which uses an electric motor mounted at the rear to power the car's back wheels when the front wheels lose traction. The AN report also repeats a rumor we've heard before – that Toyota may offer two different battery pack options in its next Prius, one using lithium-ion chemistry and one using the nickel metal hydride technology that the Prius has featured from its very beginning. While the automaker has yet to talk efficiency, it's natural to expect more capacity for EV driving from newer lithium-based technology over that of nickel-based packs to go along with what we'd also expect would be a somewhat higher price. We're sure you're just as curious about the next Prius as much as we are, and so we'll leave you with these words, again from Saga: "The batteries will be renewed. Everything will be revised. And I think we will come up with a fuel economy that will surprise everyone."
