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 RC 200t Quick Spin

Cars like the BMW 4 Series, Cadillac ATS coupe, and Audi A5 exist not as volume cars, but as aspirational products designed to draw in the young and the young at heart. The humble four-cylinder turbo, offered in each car listed above, provides an accessible point of entry for lifestyle buyers that want the statement of a sporty coupe without the eagerness, fuel inefficiency, or cost of a big six-cylinder engine. Now, Lexus is throwing its hat in the ring with a turbocharged version of its polarizing RC coupe. We took the new RC 200t out for a day on the winding roads of the Pines to Palms Highway near Palm Springs, CA, and found that while Lexus' new engine will draw new customers, they probably won't like what they find. Driving Notes The RC joins the IS, GS, and NX as members of Lexus' four-cylinder turbo clan. There's 241 horsepower and 258 pound-feet of torque on offer here, numbers that compare favorably with the BMW 428i (240 hp and 260 lb-ft) and Audi A5 (220 hp and 258 lb-ft). None of that matters, though, because the turbocharged RC is easily the slowest car in its class. You'll struggle to keep pace with stuff like the Hyundai Veloster Turbo. The RC 200t somehow takes 7.3 seconds to get to 60 miles per hour. That's a second slower than the A5, and over half a second slower than the 4 Series or Cadillac ATS. You can't drive a car that looks as wild as this and take that long to get to 60. Blame it on the RC's 3,737-pound weight. Lexus only saved 11 pounds by switching out a 3.5-liter V6 for the 2.0-liter turbo. The BMW and Cadillac both weigh well under 3,500 pounds. Even the RC's four-door fraternal twin, the IS 200t, is 150 pounds lighter (and only takes 6.9 seconds to get to 60). The RC needs a diet, plain and simple. If Lexus truly wants to compete against the Germans and Cadillac, a snappier transmission is in order. Like the GS we talked about yesterday, the Aisin eight-speed is fine on upshifts – it's still not as fast as the 4 Series' ZF eight-speed auto – but it suffers when it's time to change down. Around town, it's less of a problem, but on the twisty mountain roads outside of Palm Springs and on the freeways, the RC's gearbox kept tripping over itself. We'd love to see what the 2.0-liter turbo engine could do in a lighter car, because it's a real charmer. The broad 1,650-to-4,400-rpm torque peak gives drivers a lot of space to play, although the RC does feel flat-footed as you crest 5,000 rpm.

The new 2018 Lexus LS 500h hybrid V6 makes V8 power

With hybrids en vogue in Geneva, Lexus has taken the opportunity to debut the all-new 2018 Lexus LS 500h. The V6 is paired to two electric motors for a healthy total of 354 horsepower, just not far off the a V8-powered LS 460. It is down quite a bit from the outgoing 438-horsepower LS 600h but still enough to send the LS 500h to 60 miles per hour in 5.4 seconds. The hybrid system is similar to the one in the new LC 500h coupe, which combines the traditional Toyota hybrid two-motor CVT with a 4-speed automatic for better responsiveness, less of the "rubber band" CVT sensation, and (of course) greater efficiency. It should also help keep the LS 500h relatively quiet at full bore, keeping it in line with the "whisper quiet" mantra of the new LS. The new lithium-ion battery pack is 20 percent smaller than the outgoing nickel-metal battery, though Lexus claims power density has been improved. Styling changes to the hybrid are minor. It still features the love-it-or-hate-it spindle grille that's permeated throughout the Lexus lineup, but other than a handful of hybrid badges and the typical blue ring around the badge, it's hard to spot the difference between the models. The interior appears to have a few minor trim changes, including some new reptile scale-like door panels. While fuel economy hasn't been announced, expect improvements over the outgoing model's 19 city/23 highway rating. Look for more news on fuel economy and pricing in the next few months. Related Video:
