Watch an Aventador, Viper and LFA play the songs of their people

Our friends at Road & Track recently stopped by Cars and Coffee in Irvine, California, with the 2013 SRT Viper and found themselves a place to park between a Lamborghini Aventador and a Lexus LFA. Those machines might as well be the three musketeers of ludicrous exhaust notes, and rather than keep those 24 raging cylinders muffled, R&T set about conducting an orchestra of internal combustion. On seeing these three lined up, we were more than prepared to call the Viper victorious when it came to tickling our ear drums, but the latest domestic V10 sounds down right civilized in this company.
If we're picking favorites, we have to say the LFA takes the cake. There's something about the noise of a street-legal V10 that can wrap it's tachometer all the way to 9,000 rpm that turns our knees to quivering dollops of jelly. Check out the clip below for a listen. We shouldn't need to tell you to get frisky with the volume.

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.

Is now the time to snap up a Lexus LFA?

If you missed out on getting a Lexus LFA when it was new, the time might be near to start looking for a less expensive used one. Listings indicate that the cost for the Japanese supercar is finally starting to drop below the original $375,000 sale price. Lexus built just 500 units of the LFA between 2010 and 2012, and around 200 of them came to the US. The supercar's major highlight was the 4.8-liter V10 with 552 horsepower and a 9,000-rpm redline. It's among the best sounding engines to ever hit the street. Since production stopped, LFA prices have generally remained higher than the original $375,000, but as CarBuzz recently found that trend has shown signs of changing. The site discovered a black 2012 example on Craigslist with 2,797 miles for sale in the San Francisco for $369,000. It's quite a beauty, too. Further research shows you can find an LFA even cheaper. AutoTrader currently lists eight of the supercars for sale, including the one in San Francisco. However, another black 2012 example in Florida is just $349,000 with 2,005 miles on it. If you wait around for the right auction, there are even better deals out there. Sportscar Market reported that a White Pearl 2012 LFA went for $335,000 at a Russo and Steele auction in California in June 2015. The buyer got quite a deal because the Japanese supercar had a mere 140 miles on it. Buying a vehicle for over $300,000 is still well out of the reach for most customers, but these listings hint that LFA prices are beginning to fall. The Lexus will never be at the neighborhood used car lot, but if this trend continues, it could make for some interesting shopping. For instance, if the Japanese supercar drops into the $250,000-range, would people consider spending a little more to buy one instead of a well-optioned new Acura NSX? The Lexus' engine certainly sounds better, and the company has no plans for another supercar of that caliber. Related Video:
