Daimler consulting with Ford about 3-cylinder engines

Soon enough, Ford will offer its 1.0-liter EcoBoost three-cylinder engine under the hood of the Fiesta here in the United States, building on the success of the small powerplant overseas. In fact, this success has caused other automakers to take notice, and according to Automotive News Europe, Daimler is now talking to Ford about this engine for use in its own products.
In other markets, Ford offers the 1.0-liter mill under the hood of the Focus (we had the chance to sample this package on our home turf), as well as the B-Max MPV. For this new collaboration, Daimler would use the turbo-three in the next-generation Smart ForTwo, as well as the Renault Twingo, which the German automaker will be collaborating on as part of its alliance with Renault-Nissan. Speaking to AN, a Mercedes-Benz engineer called the 1.0-liter mill an "interesting and impressive engine."
In exchange for details about the EcoBoost inline-three, Daimler will supply Ford with information regarding its Euro6 stratified lean-burn gasoline engine, which is found in the new E-Class sedan.

Infiniti installs Taisuke Nakamura as new design chief

The cubicles and corner offices at Infiniti HQ in Japan continue to change hands. Infiniti Global Design Chief Karim Habib, only in that position for about two years since leaving BMW in 2017, has left the Japanese luxury brand "to pursue other opportunities." In his place, Nissan has elevated Taisuke Nakamura, a 26-year company veteran who is currently Nissan's program design director responsible for global design strategy, and concept car and production vehicle design. Nakamura has a stout design resume in service to both Nissan and Infiniti, having worked on the Qs Inspiration sedan concept (above) shown at the Shanghai Motor Show in April, the QX Inspiration crossover concept shown at the Detroit Auto Show this year (below), and the Prototype 10 speedster concept revealed at Pebble Beach last year (bottom). All of those were electric concepts, making Nakamura the point man for Infiniti's push into electric vehicles and hybrids, and the carmaker's introduction of a new design language. Last year, Infiniti said it would have a new EV on the market in 2021, as well as "e-Power" series hybrids with small battery packs charged by gas-powered generators.   Those EVs should fully embody the brand's new design DNA, seen initially in the recent concepts. The automaker said around the Qs reveal that the new "aesthetics are underpinned by Infiniti's desire to challenge convention and design cars which are engaging, enriching, enabling and enchanting – what the company calls its ‘4ENÂ’ approach to design." At the QX reveal in January, Habib said that as engineers made a "shift towards smarter, more compact and less intrusive powertrains, we were able to create an alternative form with flowing gestures, more engaging in character and more enriching in experience. With its long cabin, balanced proportions and muscular stance, the concept heralds in a new era for Infiniti models.” Infiniti said Nakamura takes up his post next week, Sept. 1, and will report to the same boss he has now, Alfonso Albaisa, Nissan's global design head. Aside from Habib, other top non-Japanese Nissan executives such as Daniele Schillaci, Jose Munoz and Trevor Mann have left the Japanese automaker in the recent past, since the arrest of Carlos Ghosn. The former chairman, who faces charges of fraud and misconduct, is awaiting trial in Japan over charges including enriching himself at a cost of $5 million to Nissan, Japan's No. 2 automaker.

Is the skill of rev matching being lost to computers?

If the ability to drive a vehicle equipped with a manual gearbox is becoming a lost art, then the skill of being able to match revs on downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. The usefulness of rev matching in street driving is limited most of the time – aside from sounding cool and impressing your friends. But out on a race track or the occasional fast, windy road, its benefits are abundantly clear. While in motion, the engine speed and wheel speed of a vehicle with a manual transmission are kept in sync when the clutch is engaged (i.e. when the clutch pedal is not being pressed down). However, when changing gear, that mechanical link is severed briefly, and the synchronization between the motor and wheels is broken. When upshifting during acceleration, this isn't much of an issue, as there's typically not a huge disparity between engine speed and wheel speed as a car accelerates. Rev-matching downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. But when slowing down and downshifting – as you might do when approaching a corner at a high rate of speed – that gap of time caused by the disengagement of the clutch from the engine causes the revs to drop. Without bringing up the revs somehow to help the engine speed match the wheel speed in the gear you're about to use, you'll typically get a sudden jolt when re-engaging the clutch as physics brings everything back into sync. That jolt can be a big problem when you're moving along swiftly, causing instability or even a loss of traction, particularly in rear-wheel-drive cars. So the point of rev matching is to blip the throttle simultaneously as you downshift gears in order to bring the engine speed to a closer match with the wheel speed before you re-engage the clutch in that lower gear, in turn providing a much smoother downshift. When braking is thrown in, you get heel-toe downshifting, which involves some dexterity to use all three pedals at the same time with just two feet – clutch in, slow the car while revving, clutch out. However, even if you're aware of heel-toe technique and the basic elements of how to perform a rev match, perfecting it to the point of making it useful can be difficult.
