Japanese automakers welcome North American trade deal, fear what's next

TOKYO — Toyota, Nissan and Mazda welcomed on Tuesday the revised North America trade deal that left Japanese automakers unscathed, but they may face a bumpy ride when Washington and Tokyo hold new talks on over $40 billion of annual U.S. auto imports from Japan. The United States and Canada reached an agreement on Sunday to update the 1994 North American Free Trade Agreement after Washington had forged a separate trade deal with Mexico in August. The updated deal effectively maintains the auto industry's current footprint in North America, and spares Canada and Mexico from the prospect of U.S. national security tariffs on their vehicles. Mazda, which ships cars to the United States from Mexico and Japan, called the deal a "big step forward". Nissan, which makes the cars it sells in the United States locally as well as in Mexico, Japan and other countries, said it was "encouraged" by the agreement. Toyota, Japan's biggest automaker, said it was "pleased" that a basic deal was reached. Other automakers were not immediately available for comment. While the deal has removed the risk that the disintegration of the pact would have posed to automakers, bigger risks loom large for Japanese firms as a chunk of the roughly 7 million cars they sold in the U.S. last year were shipped from Japan, and a trade deal between Washington and Tokyo has yet to be agreed. The United States and Japan last week agreed to begin fresh trade talks, with U.S. President Donald Trump seeking to address Japan's $69 billion trade surplus, of which nearly two-thirds comes from auto exports. Washington is also investigating the possibility of slapping 25 percent tariffs on auto imports on national security grounds, although it has agreed with Japan to put any new tariffs on hold during the talks. Analysts say the United States may take a tougher stance on auto imports from Japan than from its neighbors. "If Japan requests an exemption from the 25 percent tariffs under consideration, Washington could propose a more strict cap on imports than it agreed to with Mexico and Canada," said Koji Endo, senior analyst at SBI Securities. "That would be a risk." This could be a big blow to Japan, as the United States is a key source of revenue for Japanese automakers including Toyota, Nissan and Honda. The U.S. market accounts for a quarter or more of their annual global vehicle sales, and of their total U.S.

Mazda patents show rotary engine for range-extended EV

Two years ago, Mazda introduced a fascinating range-extended electric car called the Mazda2 RE Range-Extender. It took an electric Mazda2, and dropped in an itty-bitty 330cc rotary engine. It wasn't the rotary-powered sports car we had hoped for, but it seemed like a unique way to keep the quirky engine alive and kicking. But not long after the car's reveal, it seemed to disappear. Now the basic idea has resurfaced with a few modern updates in a couple of US patents. The first patent is pretty straightforward and describes a range-extended EV similar to the BMW i3. At the front is an electric motor driving the front wheels. At the back is an internal combustion engine that powers an electric generator. In the middle is a lithium-ion battery for storing and delivering electricity. It's the same set-up as that Mazda2. The second patent is for an engine start-and-stop system, but specifically for rotary engines. The system is designed to shut off a rotary engine when not needed, much as modern piston engines do. It also stops the rotor in a position that closes the intake port to ensure no fuel or exhaust emissions slip out through the intake tract. This is necessary since there are no valves in a rotary, and air and exhaust come through ports that are "opened" and "closed" by the rotor itself. The patent also describes the possibility of firing a spark plug after the fuel has been cut to eliminate any leftover fuel emissions. This system would theoretically improve a rotary engine's fuel economy and emissions significantly, which would be a boon as those are two of the rotary's major weaknesses. The rotary-engine patent also includes the same range-extended powertrain drawing as the first patent. It's there as a description of a possible application. And in such an application, where the rotary wouldn't have to run all the time, the system could take advantage of the rotary's inherent strengths. Weight can be kept low thanks to the engine's small dimensions, which should help in keeping the car sprightly and efficient. Rotaries are renowned for smoothness, too, so it shouldn't need too much refining and sound deadening, the latter of which adds more weight. The small size would also help with packaging, leaving more space for people, cargo, or possibly batteries. And since it has been patented, the company may be looking to bring the system to market.

Huet Brothers working on new Miata-based retro coupe

Does the name Huet ring a bell? The Dutch brothers started out doing classic car tours in Europe before they started designed and building their own retro sports cars. The first was called the Huet Brothers Special. It was based on an old Triumph TR6 and surfaced back in 2009. But a few years later they started showing designs for a new coupe that called for a straight-six engine under a long bonnet with a fastback roofline, and started taking orders. Over the past two and a half years we didn't see anything materialize out of the Huet Brothers' plans, but word out of the Netherlands has it that the design is back on the table.
According to the Autovisie section of Dutch newspaper De Telegraaf, Tino and Paul Huet were planning on building their coupe on the base of the MX-5 Miata. But now that Mazda is preparing to launch an all-new model, the Huets have decided to wait until next year and build their dream car on the new Skyactiv roadster chassis.
Rather than trying to shoehorn in a bigger engine (or the subsequent diesel model that was set to follow), the Huets are reportedly prepared to stick with Mazda's four-pot, offering it in stock form and various states of upgraded tune.
