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:

2019 BMW M850i xDrive: How it compares on paper with other GT coupes

Although the hot new vehicles for the rich seem to mainly comprise SUVs and supercars, the neglected luxury GT coupe segment is starting to see some life again. The latest to add a spark to this set is the 2019 BMW M850i xDrive. It goes on sale later this year, and revives the 8 Series that's been dead since the 1990s. The first version available to Americans will be one with a twin-turbo 4.4-liter V8, with other versions likely following. Before it launches, we wanted to get a lay of the grand-touring land and see how the new BMW stacks up to the competition in performance, practicality and price. While some of these models have higher-performance or more-affordable iterations, we picked the versions that would be the closest match to this 8 Series model. They include the 2019 Lexus LC 500, 2018 Mercedes-Benz SL 550, 2018 Mercedes-Benz S 560 Coupe and the 2018 Maserati GranTurismo. We will also provide some short summaries on our experiences with these cars, but to get a full picture of each model, be sure to check out their full reviews. And if you want to compare any of these cars with models you don't see here, be sure to try out our car comparison tool. Engines, transmissions and performance On paper, the BMW M850i xDrive is clearly the performer of the group. It has the most power and torque at 523 horsepower and 553 pound-feet. Coupled with all-wheel-drive and an eight-speed automatic, the car is able to overcome its relatively portly 4,478-pound curb weight to hit 60 mph in a scant 3.6 seconds. That's more than half a second quicker than the lightest car in the group, the Mercedes-Benz SL550, which weighs 4,012 pounds. The other three vehicles are in the low- to mid-4-second range to 60 mph. Though the Maserati is the slowest to 60 mph, it does boast the highest top speed of 186 mph. The M850i and SL 550 are electronically limited to 155 mph, while the Lexus is limited to 168 mph. The Mercedes S 560 has the lowest top speed at an electronically limited 130 mph. View 52 Photos Of interest is that there's a 50/50 split among these cars between using a pair of turbos, and having none at all. The BMW and Mercedes resort to forced induction, whereas the Lexus and Maserati choose to stay naturally aspirated. This is likely why the Germans break 500 pound-feet of torque, while the others don't make it to 400. Also interesting is the spread of gear quantity. The Maserati has just six ratios to choose from, and the Lexus has a whopping 10.

Toyota reveals latest autonomous tech test bed

Toyota revealed its latest autonomous technology effort Friday, a sophisticated Lexus LS 600hL prototype that showcases its plans to advance in the emerging field. The Lexus is the first developed entirely by the company's in-house Toyota Research Institute and it will focus on the car's ability to learn and see behavior on the road. Toyota is showing the car at the Prius Challenge event at Sonoma Raceway. The Lexus uses Lidar, radar, and sensors, which potentially reduce reliance on mapping. The prototype advances Toyota's last concept vehicle shown at the Consumer Electronics Show in 2013. This one is said to be more flexible and it will focus on Toyota's two autonomous tech pillars, called Guardian and Chauffeur. Guardian is meant to improve safety features, while Chauffeur moves toward full autonomy. "We believe Guardian can probably be deployed sooner and more widely than Chauffeur, providing high-level driver-assist features capable of helping mitigate collisions and save lives, sooner rather than later," Toyota Research Institute Gill Pratt said in a statement.
