Jaguar solution to keyless start could save lives

UPDATED: An earlier version of this story indicated the Jaguar keyless start function was meant as a safety feature, when in fact, it is meant as a convenience one and will not work as described if automatic stop/start is not engaged. Today, The New York Times published an article about more than two dozen deaths related to drivers accidentally leaving their cars running, closing their garages and later succumbing to carbon monoxide that flooded their homes. The reason has been identified as "keyless start" features, or proximity entry and push-button start, where owners don't need to physically handle a key or fob to gain entry into the vehicle or start it. It is the latest, and deadliest, issue raised with this system after those related to security and simple inconvenience (for instance, leaving the car at a valet or car wash with the fob in your pocket). From my personal perspective, The New York Times had a rather harsh "evil carmakers" tone throughout the article. This is not a matter of a known faulty component, as with the GM ignition switch recall. This has as much to do with user error where people leave their car without pressing the "off" button and without noticing the engine is still running. About half of the cars in question are produced by Toyota and Lexus, brands that have offered keyless start longer than most. They are also brands with high rates of elderly owners, who seemingly made up a majority of reported deaths and injuries. One fire department in Florida even started a campaign alerting those in the area of the dangers of leaving your car running when it noticed a correlation between an increase in cars equipped with keyless start and calls related to carbon monoxide poisoning. I see several contributing issues at play, most of which go well beyond this particular issue. First is insufficient training of owners by dealers and/or owners not paying close enough attention during this training. Cars are complicated, but you should at least know how basic functions work. Second, woefully inadequate driver training in this country. Third, and with apologies to the AARP, insufficient testing of elderly drivers and/or insufficiently low standards for elderly drivers. If you don't know you have to shut the car off or cannot hear that an engine is running, perhaps you shouldn't be driving. Fourth, re-examining keyless start systems.

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.

Best compact SUVs of 2022

Compact SUVs are now the go-to choice for family transportation. Actually, considering how popular they are, they have clearly moved beyond only family duty. With such popularity, though, comes an awful lot of competitors, and it can be difficult to figure out which one might be the best compact SUV for you.  It's important to note that by "compact SUV" we're talking about a specific segment. As we describe in our more comprehensive "Best small SUVs" list, there are also subcompact SUVs that vary widely in size amongst themselves, but are clearly smaller than the SUVs below. Frankly, today's segment of compact SUVs isn't exactly compact — some have more cargo space than vehicles that are considered midsize based on their exterior dimensions. They've all grown considerably over the years. While many lists out there just rattle off every vehicle available in a segment, we thought we'd be a bit more helpful and curate your shopping a bit with the top-recommended choices reviewed by Autoblog. We've included both mainstream and compact luxury SUV choices. Best compact SUVs of 2023 and 2024 2024 Honda CR-V Why it stands out: Best-in-class space; excellent hybrid powertrain; sharp interior style; Honda dependabilityCould be better: No lower-price base trim levels; no sporty or off-road niche models; no plug-in hybrid Read our full 2024 Honda CR-V Review Consider the CR-V the baseline for any compact SUV search, and look extra closely at the superb CR-V Hybrid option. Objectively speaking, it's tough to beat due to its massive cargo capacity, voluminous back seat, strong-yet-efficient engines, well-balanced driving dynamics, competitive pricing and features,  and well-regarded reliability. It's easy to see why it continues to be such a best-seller: for the vast majority of compact SUV buyers, and especially families, it checks every box. That's been the case for many years now, however. The all-new 2023 Honda CR-V changes things up by adding a bit more style and character, particularly in terms of its interior design and how surprisingly enjoyable the Sport and Sport Touring hybrid trim levels are to drive.
