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.

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.

Updated Lexus CT200h coming next year, new variants reported

Lexus has had a minor success on its hands with the CT200h, a funky, five-door, sport-luxury hybrid that burst onto the scene in 2011, and managed just over 17,000 US sales in 2012. Worked out to a monthly average, that's nearly 50 percent more units per month than Lexus initially targeted when the car went on sale.
Though it's done well, the CT has been left behind while designers and engineers have reworked the rest of the Lexus lineup, bringing out fully revamped versions of the GS, IS and LS over the past few years. According to a report from Down Under, though, the little CT will get some attention soon.
Speaking to Sean Hanley, boss of Lexus Australia, Aussie site The Motor Report picked up a telling quote about the execs affections for the CT, when he said, "We see the CT200h as our greatest opportunity." Hanley added that a refresh of the CT could happen early in 2014, while a clean-sheet reworking would happen around 2016.
