Lexus LFA prototype spied lapping the Nurburgring with new bodywork

The Lexus LFA was a real engineering tour de force. Sure, it was stuck in development hell for years, and the 4.8-liter V10's 552-horsepower output wasn't super impressive when it came out, but it integrated a ton of expertise Toyota gained from its F1 team in the early to mid 2000s. Unfortunately, it didn't sell well. Last year, we found there were a few new models sitting on dealer lots, five years after the 500-model run ended. Still, it looks like Toyota may not have given up on the idea of a race-derived flagship for Lexus, at least based on this prototype running around the Nurburgring this week. At first glance, the car pictured here looks like an LFA with the Nurburgring Package and some camouflage on the front and rear fenders. If you look closely, you can see that the fenders are significantly wider than on the standard LFA. Based on the license plate, this appears to be the same car with two different sets of wheels. Lexus may simply be swapping out worn tires, or they may be testing different wheel and tire combinations to fit the wider wheel wells. Anything beyond this is just speculation. There have been rumors of a new flagship Lexus sports car that sits atop the LC 500 and LC 500h. We saw the Toyota GR Super Sport Concept back in January, though that car looks nothing like what we see here. As much as we would love that sweet Yamaha co-developed V10 to carry over, we're not holding our breath. Some sort of hybrid powertrain is almost a certainty. Maybe Lexus and Toyota could pull some tech from its Le Mans-winning TS050 Hybrid race car. 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.

2020 Lexus RX350 and RX450h debut with refreshed styling and updated tech

The 2020 Lexus RX350 and 450h made their debuts late last night, refreshing the fourth-gen model that made its debut back in 2015. The luxury crossover gets a number of updates, with the changes mostly focused on styling, tech and safety. The new three-row model carries over, too, with the second row sporting a set of captain's chairs rather than a full bench. The 2020 RX is set to go on sale in the U.S. in late August 2019. The updated model doesn't look all that different than the 2019 model, especially from the profile. That said, the front and rear fascias have both been smoothed out, taking cues from the handsome LC coupe and LS sedan. All the lines look a bit more sleek, with thinner headlights and L-shaped blades in the taillights, again similar to the LC and LS. There's a sharp crease toward the bottom of the RX that carries across the grille, rocker panel and rear bumper. The grille itself gets a new mesh pattern. The interior is mostly unchanged, with changes mostly focused on comfort rather than design. Three-row models now have more adjustment in the back row, and the second row gets the aforementioned captain's chairs. The infotainment system gets a much-needed update. While the frustrating-at-best touchpad interface is still present, the RX now gets a touchscreen, hopefully improving one of our major complaints with the system. The RX also gets Apple CarPlay and Android Auto, something long missing from Toyota and Lexus vehicles. Voice control can be used through Lexus' own system or using Apple Siri or Google Assistant. There's also a new USB port and a phone holder to keep things in place. Underneath the skin, the 2020 RX gets a revised suspension setup and extra chassis stiffness, the latter thanks in part to new welds, high-strength adhesives and stiffer stabilizer bars. The RX has what Lexus calls Active Cornering Assist and a re-tuned stability control system to mitigate understeer mid-corner. The shocks, too, are revised to improve ride comfort and handling. Lexus says the suspension updates should improve steering feel, too. Finally, there's a few updates to the RX's safety systems. The crossover comes with the latest version Lexus Safety System +, a safety suite that includes features like pre-collision warning, adaptive cruise control, lane-keeping assist and traffic-sign recognition. The new headlights have Lexus' BladeScan Type Adaptive Headlight System, or AHS.
