Did Lexus make a BMW? Or did BMW make a Lexus? This and other 2017 surprises

It's that time of year again. The calendar is about to reach its end, Star Trek Cats 2018 is about to take its place, and I'm reflecting about all the cars that graced my driveway this year or summoned me to exotic places. You know, like Stuttgart or Phoenix. In 2017, I drove at least 57, and as I perused the list of them, I started to notice a common refrain: "This car surprised me." Most were pleasant surprises, but there were a few head scratchers and facepalms for good measure. In both cases, it was generally the result of car companies seemingly trying to break out of an existing mold. Nowhere was that more apparent than the pair of Lexuses slathered in Infrared paint: The LS 500 that left me this week and the LC 500 that was my favorite car of 2017. Though Lexus has been trying to shake its crusty, gold-packaged reputation for some time now, its efforts always seemed like an old man choosing Hollister to redo his wardrobe after realizing it hasn't been updated since 1987. I fell in love with the LC, genuinely floored by its near-perfect take on the GT. It's characterful in sound, appearance and tactility. It was at home in the city, in the mountain and on the open road. It was both comfortable and thrilling, and after driving the mechanically related LS 500, I can report that the LC's talents aren't an outlier. The LS 500's turbo V6 may make different noises than the LC's naturally aspirated V8, but it nevertheless invigorates the cabin when the car is placed in Sport+ mode. The steering is truly communicative, body motions are kept in miraculous check, and I absolutely forgot I was in an enormous luxury limo ... and a Lexus one at that. It was everything that the BMW 530e was not. I drove that on the exact same roads and was utterly bored the entire time. Generally doughy, lifeless steering, more distant than Planet 9. And no, the plug-in hybrid powertrain had nothing to do with that. At least it shouldn't. The Porsche Panamera S e-Hybrid I also drove this year proves that, as do the Hyundai Ioniqs, which are surprisingly adept and fun little cars regardless of what powers their wheels (Hyundai + hybrid = fun really blew me away). I would drive that Lexus LS F Sport over the BMW 5 Series any day of the week, which seems like a shocking thing to say in relation to either car. While Lexus is seemingly breaking out of its old crusty mold, BMW seems to be climbing into one.

Toyota finds 10% MPG improvement in hybrid PCU

Keeping up its from-all-angles approach to efficiency, Toyota has found yet another way to eke out up to ten percent more precious MPGs in its hybrid vehicles, this time electronically. The automaker has announced the development of new silicon carbide (SiC) power semiconductors for use in power control units, which it will begin testing on Japanese roads within the next year. The PCU using the silicon carbide compound offers less electrical resistance, which improves efficiency when passing current between the battery and electric motor. It also loses less power after shutting off, and can operate at a higher frequency. The net power loss of the new PCU is just one-tenth of the current silicone-only version (the latter accounting for 20 percent of total electrical power loss in today's hybrids). The result, so far, is a claimed five-percent improvement in fuel economy in test vehicles, with the potential of ten percent by the time the new SiC power semiconductor comes to market. Additionally, the carbide wafers allow for smaller a power module, coil and capacitor, thus allowing the entire PCU to be 80 percent smaller (see the side-by-side comparison in the accompanying photo, which you can click to enlarge). We've got a while to wait before we start to see the carbide technology to start making a real-world impact. Toyota aims to begin using the SiC units in 2020. By then, with improvements in the company's other key efficiency factors - engine technology and aerodynamics - cars like the Prius will likely see significant gains in fuel economy. Read more in the press release below. Toyota Develops 'Diamond-like' Computer Chips to Boost Hybrid Mileage May 20, 2014 Toyota City, Japan – Toyota is using one of the hardest materials in nature after diamonds to develop a semiconductor chip it hopes will improve the fuel efficiency of its hybrids, such as the Prius, by as much at 10 percent. The company and its partners announced today that they have developed a silicon carbide (SiC) power semiconductor for use in automotive power control units. Toyota plans to begin test-driving vehicles with the technology on public roads in Japan within a year. The chips, made from carbide - one of the hardest materials in nature, theoretically have superior characteristics such as one-tenth the electrical power loss and 10 times the drive frequency. Toyota said the chips would also allow it to reduce the size of current automotive power control units by 80 percent.

Toyota Recalling 1.67 Million Vehicles Worldwide

UPDATE: Toyota is now announcing specifically which models are covered under its fuel pipe recall in the US. The company is repairing about 423,000 Lexus models that include the 2007-2010 LS, 2006-2011 GS, 2006-2011 IS, 2010 IS C and 2008-2010 IS-F. The automaker says that it isn't aware of any fires, crashes, injuries or fatalities caused by this problem. According to Toyota, the recall is because it's possible for the fuel delivery pipes and the fuel pressure sensor to form a bad seal with the gasket between them because of a protective coating protecting against corrosion on the pipes. It's possible for this to eventually cause a fuel leak, and obviously in a hot engine bay that's a potential fire risk. To fix the problem, dealers will replace the gasket and repair the gasket seating surface between the fuel delivery pipe and the fuel pressure sensor. The company will begin notifying owners soon. You can find the official press release, below. Toyota is issuing three separate recalls covering 1.67 million vehicles worldwide with most of those models in Japan. It looks like the campaigns' impact on the US may be smaller, though. According to Reuters, Toyota isn't aware of any accidents, injuries or fatalities affecting the models. Some yet-unnamed Lexus models might also be affected. The largest of the campaigns does not currently affect any US-market vehicles. About 802,000 units of the Toyota Crown Majesta, Crown, Noah and Voxy in Japan are being repaired to replace a seal that could leak in the brake master cylinder. Those already leaking get a new brake booster, as well, according to Reuters. The only recall currently believed to affect the US is due to a problem covering approximately 759,000 vehicles with 423,000 of them here. The repair is to fix a faulty fuel delivery pipe that could cause a fire if the fuel leaks out. Unfortunately, we don't know which models it covers. Autoblog spoke to Toyota spokesperson Mona Richard and was told the information was still "under embargo." When exactly that embargo will lift isn't yet known, but we're on the case. Finally, Toyota is recalling 190,000 Corolla Rumion and Auris models in Japan for a faulty evaporative emission control unit. Autoblog is in contact with Toyota, and we'll update this story as soon as we know more about its affect on the US market.
