IIHS Top Safety Pick and Top Safety Pick+ awards get tougher: Here are the latest winners

Automakers love to trumpet the accolades from the Insurance Institute for Highway Safety, but the agency keeps making its best grades harder to achieve. For 2020, it is raising the bar again, requiring a better score in the passenger-side small-overlap crash test, wider availability of top-performing headlights, and automatic emergency braking systems that effectively avoid collisions with pedestrians, in addition to its previous benchmarks. Why the 2020 criteria is harder: To be named either a Top Safety Pick or Top Safety Pick+, the required performance in the passenger-side small-overlap crash test has been raised from Acceptable to Good, meaning that the model must achieve Good ratings in all crash tests. The Nissan Rogue, for example, scored an Acceptable in the passenger-side small overlap crash, and so it loses its Top Safety Pick rating for 2020. To achieve either of the top ratings, a vehicle's automatic emergency braking system must effectively avoid hitting pedestrians as well as other vehicles. (The automatic emergency braking system can be optional, but then the award applies to the model only when so equipped.) Any vehicle whose automatic emergency braking system does not include pedestrian detection would lose its TSP or TSP+ rating for 2020, the Ram 1500 being one example. To be named a Top Safety Pick+, the model can have no variant with headlights that achieve less than an Acceptable rating (most new cars have different headlights — often LEDs — that are exclusive to upper trim levels).

2016 Mazda MX-5 Miata Launch Edition now available for pre-order

Want to be one of the first to buy the fantastic new 2016 Mazda MX-5 Miata? Now's your chance.

All of the MX-5 Miata Launch Edition cars come painted in Soul Red with a Sport Tan leather interior, an exclusive combination for this special run. Buyers only need to choose between the six-speed manual transmission (the obvious choice), or a six-speed automatic. Pricing is set at $30,495 if you want the stick-shift, and $31,570 if you prefer the auto. So, want one? Of course you do. Head over to Mazda's pre-order site and place a $500 deposit toward the purchase of your car. Better act fast, though. When Mazda offered its 25th Anniversary MX-5 Miata via pre-order, all 100 of those cars sold out in just ten minutes.

Mazda files patent applications for inline-six technology, new transmission

We've known for some time that Mazda is one of the OEMs getting back on the inline-six engine bandwagon, and a report from Japan gives us a glimpse of some of the automaker's plans. Mazda has filed patent applications for both new exhaust components (depicted with an inline-six) and a new eight-speed automatic transmission.  The news comes from a blog called T's Media (fire up Google Translate), which located the new hardware in two separate fillings, one for exhaust system components and one for the new transmission.  Mazda's lineup has been exclusively powered by four-cylinder engines since the demise of the last-generation CX-9, which utilized a 3.7-liter V6 sourced from Ford. Since, Mazda has relied on turbocharging to get more power out of its SkyActiv four-pots, but changes may be coming. Prior reports have indicated that Mazda wants a new, larger engine architecture to power vehicles built on a new, larger platform. This new chassis is expected to accommodate longitudinal, rear-wheel drive powertrains, which could spawn larger crossovers and SUVs. It could also potentially underpin a new rear-wheel drive coupe, if Mazda decides to go that route.  While the inline engine itself is not news, what we're seeing here might actually be hints as to Mazda's approach to the next generation of its SkyActiv engine architecture. Mazda's exhaust patent seems to describe a scalable — perhaps even modular — setup intended to be used with inline and potentially even V-engines.  "Provided is an engine exhaust structure capable of securing exhaust efficiency while reducing the size of the engine by changing the structure of an exhaust port," a translation of the patent application's introduction says. "[T]here has been proposed a technique for collecting exhaust gas discharged from each cylinder inside a cylinder head without using a separate exhaust manifold with the aim of downsizing the engine." In other words, Mazda is looking for ways to make its future engines more compact, and the strategy detailed here is the use of an integrated exhaust manifold, similar to what other automakers (such as Honda and Ford) have utilized on their smaller-displacement turbocharged engines. The sketch above of an inline-six engine with just two exhaust ports illustrates this concept.  The eight-speed transmission, while noteworthy in its own right as Mazda currently relies on aging six-speeds, doesn't seem to offer us anything particularly game-changing.  Related Video:
