Lexus teases new F Sport engine cover

Lexus has teased a new F Sport model by revealing just the engine cover. It could point to a new performance version of the 2021 Lexus IS, and a potential successor to the dearly departed IS F. The image was obtained by Lexus Enthusiast, which pointed out that the carbon-fiber pattern cover is exactly the same shape as the one found shrouding the 5.0-liter V8 that powers the GS F and RC F. Good for 467 horsepower and 389 lb-ft of torque and a symphonic revving sound, the 2UR-GSE has traditionally been the heart of Lexus's F performance line. The teased cover, however, shows an "F Sport" badge where the GS F and RC F's "F" badge once resided. That implies a car with stiffer sport suspension along with some of the styling of a full-blown F model, but not the full stable of horses under the hood. Recently, Best Car magazine reported that Lexus was about to come out with a trio of F models. We think this engine cover is unlikely to preview an LC F, as the LC 500 is already powered by the 2UR-GSE, and wears a completely different engine cover. Also, an LC F would likely be turbocharged and thus don a different cover altogether. While it's possible that Lexus would drop the more powerful 2UR-GSE into the LS to give it a 73-horsepower bump over its current 394, that would imply an LS F model, not a simple F Sport. And besides, the LS already has an F Sport variant. The Best Car report also indicated that the LS F in the works, if it happens at all — and that's a big "if" — would be propelled by a twin-turbo V8.  That leaves the new IS, which in its most powerful guise has a 3.5-liter V6 generating 311 horses and 280 lb-ft of torque. It's possible that rather the teased engine cover is foreshadowing an IS 500, a conclusion that Lexus Enthusiast also draws, albeit with slightly different reasoning. An IS 500 would be one way for Lexus to squeeze as much use out of its marvelous 2UR-GSE before the V8 goes the way of the dodo, but without having to develop an all-out F model. The original IS F had, among other things, wider body panels, six-pot front brake calipers with cross-drilled rotors, and a Torsen LSD. By not calling an IS F, Lexus could be lowering expectations for enthusiasts of the original who would expect those performance features. Or, if the V8 gods are listening, perhaps Lexus is saving the true F badge for an IS with the rumored twin-turbo powering the LC F. One can hope, right? Related Video:

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 LC 500 stands apart from the go-fast sport luxury crowd

We at Autoblog, by and large, love the LC 500. For its concept-car looks, derived almost verbatim from the 2012 LF-LC concept. And for the charming V8, which growls and burbles appropriately but doesn't subscribe to the faux-backfire trend. Our Editor-in-Chief, Greg Migliore, perfectly summarized the LC 500's appeal when he drove it recently: "Evening walkers cast curious glances. A guy in an old pickup almost sideswiped me as he gawked while taking the corner fast. It's a celebrity car. It also sounds good; the 5.0-liter V8 growls and rumbles. Style and muscle. An excellent execution." I just spent a week in it, my first encounter with the car, and it made me think most about how it's positioned in the Lexus lineup. Notably, it's not positioned as the performance extreme. This is refreshing, because not every car needs to attempt a Nurburgring time. If you want to hunt road-course records in this day and age, it takes massive power and massive traction. We're getting to the point, perhaps well beyond it, where that is doing the stopwatch more favors than the driver. Part of this is decades of marketing putting the sportiest variant of a particular vehicle above the most luxurious in the pecking order of regular vehicles, which doesn't make a ton of sense if you think about it. In the 1960s, the ultimate Mercedes-Benz was the 600 Grosser limousine, which was built like a Rolex bank vault. It had a huge engine, but the point was to move the massive thing around, not for the sheer pleasure of it. Ironically, the Grosser's engine made its way later into the 300 SEL 6.3, turning a large and luxurious sedan into a surprisingly capable bruiser, and then into the Rote Sau race car. Arguably, this was an impetus for the sort of sporty arms race I'm decrying. (Now, when you talk about supercars, or ultimate luxury cars like a Bentley or Maybach, this distinction makes less sense. But let's limit our discussion to vehicles the well-heeled average consumer could actually purchase — things at the upper end of the ranges of normal car manufacturers.) This takes us to the Lexus LC 500. Unlike Mercedes, whose Mercedes-AMG cars are on top of the regular car pecking order, Audi's RS line, BMW's M Division, and Porsche's various Turbos, the LC 500 is simply a large, powerful car. It's comfortable, it looks interesting, and it has more than enough grunt to get out of its own way. There are Sport and Performance options packages, but there's no LC F or F-Line trim available.
