Cafe racer motorbikes storm Japan

Japan may be best known, at least among motorcycle enthusiasts, for its sport bikes. But as we found at the Tokyo Motor Show this year, Japanese motorcycle manufacturers are capable of producing all kinds of motorbikes. And to our delight, that includes cafe racers.
Along with the myriad electric bikes, dirt bikes, crotch rockets and scooters, the halls of Tokyo's Big Site convention center this year were full of the retro-infused rides we love. Chief among them was the Bolt (shown above) which Yamaha exhibited alongside their various electric two-wheelers, sporting a delicious metallic blue paintjob, inverted handlebars and hanging mirrors, machined metal bits, blacked-out trim and saddle brown leatherwork.
Honda was also on hand with a new EX version of its '70s-style CB1100 retro roadster in sinister and low-key matte black. And this was our first chance to check out BMW Motorrad's new birthday present to its 90-year-old self, the R NineT, a model recently unveiled at the EICMA motorcycle show in Milan. But one of the most amusing retro rides we came across was the Honda Monkey Limited, a mini bike that makes the new 125cc Grom (which was displayed alongside it) look positively gigantic.

BMW reveals M4 safety car with innovating water injection system [w/video]

Racing series don't just pick their safety cars at random, or use just whatever car is lying around. These days the car that sets the pace at the front of the pack is typically provided through consideration by a sponsor. In the MotoGP series, that's BMW and its M division, which have served up the Official Car of MotoGP since 1999. What you're looking at is the latest, and it packs some innovative technology on board. Aside from the matte black wrap with BMW's iconic striped livery, upgraded aero kit, retrofitted interior and emergency equipment, this BMW M4 coupe packs a new injection system under the hood. Only instead of injecting fuel, it injects water into the combustion chamber – something that wouldn't usually be recommended, but BMW insists actually aids in the combustion process. The idea is that the temperature of the air being mixed with the fuel inside the engine is usually hotter than ideal, so the system injects a fine mist of water into the collector in order to reduce the air's temperature... sort of like one of those hydrating misters at an amusement park or outdoor mall, but in an even hotter environment. The system brings the temperature of the air down to a more optimal temperature, helping it combust better. The process is said to yield a number of positive effects. For one, it reduces knocking. For another, it can make more out of lower-octane fuel where higher octane isn't available. It also can control the adverse effects of higher ambient temperature on the combustion process. But most of all, it increases output and reduce fuel consumption by around eight percent. Whether that eight percent is worth the added weight of the system – particularly with water pump and a 1.3-gallon tank in the trunk – is up for debate. But we'd imagine that the Bavarian engineers have weighed very carefully. Of course there's also the matter of refilling the water tank, which BMW says would be carried out whenever the safety car is refueled, but in real-world conditions would only necessitate attention once every five top-ups at the gas station. By now you might have guessed that BMW probably didn't develop this system just for the MotoGP safety car, and isn't planning on keeping it confined to the racetrack. Instead it's being tested and demonstrated on the safety car before being rolled out on production models in the future.

Car technology I'm thankful and unthankful for

The past few years have seen a surge of tech features in new vehicles — everything from cloud-based content to semi-autonomous driving. While some of it makes the driving experience better, not all tech is useful or well thought out. Automakers who are adept at drivetrains, ride quality and in-cabin comforts often fail at infotainment interfaces and connectivity. From testing dozens of vehicles each year and in the spirit of gratitude, here are three car tech features I'm thankful — and a trio I could live without. Thanks Connected search: This seems like a no-brainer since everyone already has it on their smartphones, but not all automakers include it in the dashboard and as part of their nav systems. The best ones, such as Toyota Entune, leverage a driver's connected device to search for a range of services and don't charge a subscription or require a separate data plan for the car. I also like how systems like Chrysler Uconnect use Yelp or other apps to find everything from coffee to gas stations and allow searching via voice recognition. Apple CarPlay and Android Auto: It took two of the largest tech companies to get in-dash infotainment right. While they have their disadvantages (you're forced to use Apple Maps with CarPlay, for example), the two smartphone-integration platforms make it easier and safer to use their respective native apps for phoning, messaging, music and more behind the wheel by transferring a familiar UI to the dashboard — with no subscription required. Heated seats and steering wheels: I really appreciate these simple but pleasant features come wintertime. It's easy to get spoiled by bun-warmers on frosty mornings and using a heated steering wheel to warm the cold hands. I recently tested a 2018 Mercedes-Benz E400 Coupe that also had heated armrest that added to a cozy luxury experience. Bonus points for brands like Buick that allow setting seat heaters to turn on when the engine is remotely started. No thanks Automaker infotainment systems: Automakers have probably poured millions into creating their own infotainment systems, with the result largely being frustration on the part of most car owners. And Apple CarPlay and Android Auto coming along to make them obsolete. While some automaker systems, such as Toyota Entune and FCA's Uconnect, are easy and intuitive to use, it seems that high-end systems (I'm looking at you BMW iDrive and Mercedes-Benz COMAND) are the most difficult.
