2018 Lexus LS First Drive | Luxury, performance and the puzzling parts

When one imagines the enormous executive sedan that might be driven by a wealthy lawyer or banker (or their chauffeur), the mind naturally goes to the Mercedes S-Class or the BMW 7-Series. Venerable, enormous and expensive. But for those wanting to keep their driveway a little more understated, we also have the Lexus LS. Sure, it's not as ostentatious as the big saloons from Munich and Stuttgart, but it has a dignified elegance all its own. For nearly three decades, the LS has been a discrete and dependable Japanese luxury sedan. The new 2018 LS, perhaps thankfully, is a bit less discrete. We saw the new-look LS when it was introduced earlier this year in Detroit. Now we know how it drives. We put the 2018 LS through its paces on the traffic-clogged streets of San Francisco and over the Golden Gate Bridge to the twisty B-roads around Marin County and the legendary Skywalker Ranch, where we stopped for lunch. Unfortunately, all in attendance were sworn to secrecy about the details of Skywalker Ranch, but we're free to tell you all about the LS. Here's our one-sentence summary, which can be used to describe many cars to bear the Lexus badge: It's excellent in many respects, odd in a few, and incredibly, massively frustrating in one very important area. Lexus has a brand new 3.5-liter twin-turbocharged V6 paired with a 10-speed automatic transmission, a first for a premium passenger car. It produces 416 horsepower and 442 pound-feet of torque, up from 386 hp and 367 lb-ft from the outgoing naturally aspirated 4.6-liter V8. Lexus engineers are extremely proud of the fuel efficiency of the new engine, which required some clever technical innovations (a longer bore stroke and increased valve angle) as well as tech borrowed from Formula One, including a "laser clad valve seat" that allows for a more direct flow of air into the combustion chamber and a high "tumble ratio." In other words, Lexus figured out how to get more bang out of each gasoline-powered buck. Fuel economy numbers are 19 city, 29 highway, and 23 combined for the RWD version and 18/27/21 for AWD, with the highway numbers particularly helped along by the 10-speed gearbox. It's a torque converter unit, but Lexus promises shift times that rival its dual-clutch-wielding competitors. The LS is no slouch, either. In RWD trim, the nearly 5,000-pound car hustles from 0-60 mph in 4.6 seconds, according to Lexus' reckoning.

2022 Lexus NX gets new chassis, engines and even a PHEV

The Lexus NX is one of the more recent additions to the Lexus lineup, having made its debut for the 2015 model year. In that time, it's only received a couple of facelifts. Now, the small crossover is getting its first full redesign in the form of the 2022 Lexus NX. And while it may look evolutionary, it offers a load of new and welcome features. The new NX is now built on the TNGA-K platform, which also underpins the Toyota RAV4 and Camry and the Lexus ES among other small to midsize models. Lexus says it's structurally more rigid and offers a lower center of gravity. Fitted to this platform is a plethora of powertrains. The NX 250 gets a naturally aspirated 2.5-liter four-cylinder making 203 horsepower and 184 pound-feet of torque. It's available with front- or all-wheel drive. The NX 350h hybrid gets the same engine but with a couple of electric motors. That gives it all-wheel drive as well as 239 horsepower. The regular NX 350 gets a turbocharged 2.4-liter four-cylinder making 275 horsepower and 317 pound-feet of torque, plus all-wheel drive. Topping the range is the NX 450h+ with the RAV4 Prime's 2.5-liter four-cylinder and larger electric motors making 302 horsepower. It's also only available with all-wheel drive and has a 36-mile electric range. The non-hybrid powertrains now come with an eight-speed automatic, but the hybrids continue to use CVTs. All of these new mechanical updates fit under a fresh but familiar-looking shell. It's short and taut with many curves and creases, but it's generally smoothed and softened compared to the previous model. The most distinct change is at the rear where the NX adopts a full-width taillight like the IS and UX. It also features the brand's name spelled out in letters just below the taillight. The inside is more significantly updated, and the focal point is undoubtedly the new infotainment system. The old touchpad and mouse designs are dead, and the NX will be the first to use this new touchscreen system. It was developed by a division at Toyota's North American headquarters, and seems much more intuitive, though we'll have to reserve final judgment until we try it ourselves. It uses either a 9.8-inch screen or optional 14-inch unit. The latter incorporates dedicated touch buttons for comfort controls and physical temperature dials blended into it. The smaller screen uses all physical controls for comfort functions. Both have a physical volume knob, too.

Toyota Camry, Lexus RX to get aluminum parts

Ah, aluminum. The lightweight, strong material has long held a following within the premium ranks, but as Ford prepares to launch an aluminum F-150, the material is gaining acceptance among more mainstream automakers. Toyota is one such brand, with a new report indicating that the Japanese giant will add aluminum bits and bobs to some of its upcoming vehicles.
These won't be full, aluminum-intensive treatments like the F-150, however. Automotive News reports that an aluminum hood and liftgate will be coming to the 2016 Lexus RX, and following that, the Camry will get a bonnet built from Element 13 for model year 2018.
As AN points out, Toyota is no stranger to aluminum, using it in Japanese-built models like the Prius and Scion FR-S. The RX and Camry, though, will mark the first time the company's North American factories will use the material, and they'll do so on a significantly larger scale, owing to the higher volumes that the Camry and RX represent.
