Toyota twin-turbo V8 patent unearthed

An unremarkable patent focusing on a minor engine part has revealed that Toyota is at least considering a twin-turbo V8. While the filing is most likely just a large company protecting its intellectual property, it could also be a small glimmer of hope that Toyota, a storied company that's made some glaring missteps with enthusiasts in recent years, can leave the ICE party with a bang for the ages. The patent for a secondary PCV separator, whose function is to isolate exhaust gas from lubricating oil, was discovered by a member of the GR86 forum. In this case, it's not engine oil that's the culprit, but turbocharger oil. From a twin-turbo V8. The patent starts out with an almost embarrassingly hilarious stick figure drawing of a car and where said engine would be located (in the front, under the hood, duh). It has the words "Internal Combustion Engine" printed on a rectangle in case there was any doubt. However, the second figure shows a dual turbo setup nestled in the valley of a V8. It's a prime location for reducing turbo lag and optimizing throttle response (and should necessitate a substantial hood bulge as well). Now, interestingly, the forum member believes this engine will be installed in the next Tundra (and presumably Sequoia), but our own research indicates that the pickup will have a 3.5-liter twin-turbo V6 under the hood. With all due respect to the GR86 members, we're going to stand by that assertion and cross our fingers that the patent hints at something even better. That would be a high-performance Lexus, possibly an IS F or, if the ICE gods will allow it, an LC F. After all, we have had reports from Japan that a trio of F-cars were coming, including a LS F. It would explain why the 472-horsepower, V8-powered IS 500 was called the Sport Performance instead of full-on IS F. In fact, Lexus reps have promised that the F label would become even more performance oriented. A proper IS F would be a fitting sendoff to Toyota's high-performance V8, but the tested, then reportedly canceled, then reportedly revived LC F would be an even more melodious swan song. The flagship grand tourer could very well allow loyalists to forgive the aforementioned gaffes. Toyota president and noted car guy Akio Toyoda has taken heat for questioning the coming outright ban of ICE sales in his home country of Japan. Perhaps this engine is one of the reasons he's objecting.

Lexus LS mid-cycle refresh to restore V8-powered LS 600h hybrid?

When Lexus launched the fifth-generation LS at the end of 2017, the Japanese luxury maker predicted its once-brand-defining sedan would sell 12,000 units per year in the U.S., a threshold the model hadn't reached since 2010. The LS managed 9,301 transactions here in 2018, its first full year on sale, falling back to 5,528 units in 2019. Through the first three coronavirus-affected months of this year, Lexus dealers have sold 801 LS sedans, compared to 1,404 units in Q1 2019. There's a mid-cycle refresh supposedly due for release in the fall of 2021, and the June issue of Japanese magazine Mag-X (translated), via Lexus Enthusiast, claims we're due for a couple of big surprises that could jolt the sales figures. The first shock is that Lexus is supposedly bringing back the LS 600h moniker for an LS with a V8 hybrid powertrain.  Lexus debuted the LS 600h L in 2007 for the 2008 model year, retiring the hybrid trim in 2016. Its heart was a 5.0-liter naturally aspirated V8, and when combined with an electric motor, combined output came to 439 horsepower and 385 pound-feet of torque. The fifth generation introduced the LS 500h that switched to a naturally aspirated 3.5-liter V6, producing a combined 354 hp and 369 lb-ft., taking second place in output to the twin-turbo V6 in the non-hybrid LS 500 with 416 hp and 442 lb-ft. If Lexus were to double back to a V8 after experimenting with a V6 hybrid for four years, some question which V8 would get the nod. The old V8, codenamed 2UR-FSE and still in use in the Lexus LC as the 2UR-GSE, dates back 14 years and is scheduled to retire in two years when the LC-F introduces Lexus' new twin-turbo V8. According to leaked dealer information, that's the same year Toyota and Lexus will stop offering V8 engines in any model with an MSRP under $90,000. Toyota has shied away from turbocharged hybrids, but the next-generation Tundra could change that if rumors of the 3.5-liter twin-turbo V6 i-Force Max engine come true. A twin-turbo V8 LS hybrid would rocket the model back to the top of the range in performance and price, and we could see it breaking the "F" seal on the LS lineup, since it would run counter to everything the German competitors are doing with their standard flagship sedans. Or Lexus could remove the turbos for a better compromise of potency and frugality.

Lexus still planning seven-seat crossover

In case you're thinking, "But Lexus already has a seven-seat crossover in the GX 460," that's actually a proper SUV - the body-on-frame kind with the massive footprint and floaty handling. A report in Automotive News says that Lexus is trying to figure out how to produce a true crossover with space for seven humans, with the options narrowed down to growing the RX (pictured) or sorting out a brand new model.
How badly does the brand want it? Its chief told AN that another row is first on the list of dealer requests, that the offering could be worth 35,000 more sales per year and they don't care if it eats into five-seater RX sales - "We want it." But hey, when 40 percent of monthly sales are made up of the RX, and Lexus moved more than 103,000 of them in 2013, it's understandable that the company wouldn't mind risking a small hit for the chance to increase sales by a third of their current levels.
Toyota applied to trademark the name TX and that's already been mooted in reports as a replacement for the GX, said to end its life in 2016. The latest report, however, suggests that the GX might not go away since it's "highly profitable for the automaker, even at low volumes," and that "TX coding could merely be for a seven-seat variant of the RX 350." AN also wonders if this larger hauler would stay on the recently lengthened Toyota Highlander platform, which offers meager third-row seating, or switch to the rear-wheel-drive platform used by the IS and GS for tauter responsiveness. With Lexus saying it will be at least two years before it could be brought to market, we have a while to wait yet to find out.
