Lexus to use BMW 3.0-liter straight-six in next-gen IS sedan?

Here's a rumor so wild it needs a U.S. Fish and Wildlife permit. Japan's Best Car magazine reports that the next-generation Lexus IS will offer BMW's B58 3.0-liter inline-six as one of four powertrain options. That's the same engine found in the new Toyota Supra with 335 horsepower and 365 pound-feet of torque. What's more, the fourth-gen IS will resurrect the IS F model gone AWOL during the current third generation, and do it with the twin-turbo V6 from the Lexus LS 500. The current TTV6 makes the same 416 hp in the LS 500 as the 5.0-liter V8 did in the first Lexus IS F 12 years ago. According to the magazine, the other engine options would be Toyota's 2.0-liter turbocharged four-cylinder, a 2.5-liter for a hybrid model, and a 2.4-liter turbo. We don't know where that last engine fits in. BMW doesn't make a 2.4-liter, and Toyota appears to have retired all of its 2.4-liter applications. Ignoring that, the 3.0-liter straight-six looks like it would replace the current 3.5-liter V6 rated at 311 hp and 280 lb-ft. This wouldn't be the first time the Supra's engine has been ported to the IS. Lexus mavens will remember that two years after the introduction of the original IS in 1998, Lexus put the Supra's 2JZ 3.0-liter straight-six engine in the IS 300 — without the turbochargers, thank you. But Best Car's prediction would have zero relation to history. Those were both Toyota engines back in 2000, and even ignoring the power differential, the IS didn't compete with the Supra. Putting BMW's 3.0-liter in the Z4 and the Supra works because they are the same car. And again, even ignoring the power differential, the more powerful Z4 doesn't compete with the Supra. Best Car's scenario has BMW selling one of its best engines for use in a direct competitor to the 3 Series. Lexus would need to design an engine bay long enough to swallow an inline-six, not a bread-and-butter engine for the brand, yet still be sensible for three more compact powerplants. Then, assuming BMW and Toyota made the same deal as with the Z4 and Supra, the Lexus would be down by a healthy double-digit horsepower margin on its German foe. The new Supra gives up 47 hp to the roadster. Where's the upside? It's said the trim sedan will stay about the same size, on a wheelbase roughly four centimeters longer, but lose a substantial chunk of weight.

Toyota shows a smoother autonomous Lexus for CES

Toyota is bringing a new research vehicle to CES. The TRI-P4 autonomous driving test vehicle, based on the Lexus LS500h, is a major step ahead, according to Toyota, as it has improved computing power and additional cameras for better reaction times. Earlier test mules have also used the LS as a basis, and the shift to the new, fifth generation LS brings chassis and steering-control benefits, so the vehicle's movements are smoother in automated mode. The camera tech has also been better integrated into the vehicle design, courtesy of CALTY in Ann Arbor, Michigan. Development has been swift, as the TRI's P2.1 car was unveiled in 2017. The P4 car will be used for Toyota Research Institute's Guardian and Chauffeur mode development. The two tiers differ somewhat, as TRI's Ryan Eustice explains: "Our Chauffeur development is focused on full autonomy, where the human is essentially removed from the driving equation, either completely in all environments, or within a restricted driving domain. Guardian, on the other hand, is being designed to amplify human performance behind the wheel, not replace it. The introduction of the new P4 platform will help us accelerate the development of both tracks when it joins our fleet this spring." The vehicle's situational awareness is boosted by two extra cameras facing on the sides, and a new imaging sensor both forward and rearward. Toyota says the P4's lidar setup is a carryover from the previous platform, but that its machine learning is much improved by its more powerful computer setup. The electricity required by the P4's computing power also comes from the hybrid battery, and as the computer "brain" is now housed vertically against the rear seat's backing, actual trunk space has been freed. More LS500hs will begin to be modified into TRI-P4 vehicles during spring 2019. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.

Lexus F label to become even more performance oriented

Lexus has plans to take its F performance label to even greater heights, according to officials. That's one of the key reasons the IS 500 F Sport Performance wasn't a full-blown IS F, Lexus executives said. Speaking before a gathering of Lexus enthusiasts at the IS 500 Launch Edition's, uh, launch at Sebring Raceway, group vice president and general manager of the Lexus division Andrew Gilleland reaffirmed that the IS 500 F Sport Performance is the first in a line of high-performance but sub-F cars (at 5:11 in the video below). "There will definitely be more vehicles. There's a lot more coming where this came from," Gilleland said, eliciting cheers from the gathered crowd of enthusiasts.

Gilleland then pointed at Lexus product planner Cooper Erickson and told the fans, many of whom had brought their own tuned F cars to the event, "If you want to see more of this," gesturing to the IS 500, "Go bug the s--t out of him." Erickson himself then took to the stage and discussed how the IS 500 came to be and the future of the F designation (at 6:17 in the video). First, he acknowledged that sedan sales are challenging. He also described the 2021 IS's chassis as a combination of the GS and RC platforms, which grew the track 1.4 inches wider. "If it's part GS and part RC, then why can't we drop a big-ass V8 in it?" Erickson wanted to know. "Nobody's doing that. But, we can," Erickson continued, "Because we do an amazing job with our hybrid products. So from a CAFE, greenhouse gas and emissions standpoint, we can manage having a V8 in a car like this when nobody else can." However, it still required approval from the mothership in Toyota City. So during an event at Pebble Beach, Erickson told Lexus chief engineer Koji Sato that he wanted to bring back the IS F. "Let's put the V8 in it, Let's do an IS F," he told Sato. At first, Sato's reply seemed like a no. "We have new plans for F," he explained. "F will be higher. Only Akio [Toyoda] can approve F [cars]." The CEO is known for being one of the few carmaker heads that actually moonlights as a racing driver. Erickson said that even if the IS F was off the table, he still wanted a V8-powered IS. "So what if we call it IS 500 F Sport? Who can approve that?" Sato's reply: "Cooper-san, I can approve that." Apparently the rest is history. This content is hosted by a third party.
