Reliability and practicality that can be used as everyday feet │ Reassess Porsche "Nanasan" Carrera

This article isRe-evaluating "Nanasan" Carrera│Where is the source of its charm?It is a continuation of.

The 6-cylinder engine for the Carrera RS, which was expanded from 2.4 liters to 2.7 liters, generated 210ps/6300rpm and 255Nm [26.0kgm]/5100rpm. The Nikasil [compound of nickel and silicon carbide] plated cylinder, which was used in place of the conventional steel liner, is a diversion of racing technology.

After that, depending on the model, Arsyl [aluminum/silicon] cylinders were sometimes used, but Porsche has long been active in introducing cutting-edge materials. The high-performance 2.4S before that also produced 190ps, so the increase in power was not so remarkable, but the flexibility was further increased by increasing the torque by increasing the displacement. The manufacturer's nominal maximum speed was 240 km/h, 0-100 km/h acceleration was less than 6 seconds, which was amazingly fast at that time, but it blew up sharply like a razor, but it was a cumbersome flat six engine, peaky and nervous. The public opinion of handling is perhaps, or in my experience, an almost urban legendary misconception.

Both the 911 and the previous 356, the Porsche is a practical sports car and a GT car that can withstand long-distance travel. High performance but practicality is important, and a feature that is crucially different from many sports cars of the same age. It is not a weekend sports car that pulls out of the garage a little on a sunny day, skips the mountain road and releases stress. That is why even in modern Japan, it has the reliability and practicality to be used as a daily foot without problems.

From the modern point of view, the maximum output of 210ps is negligible. However, at that time the body size of the 911 Carrera RS was less than 4.2 m in overall length and 1.66 m in width, and it was compact and lightweight enough to fit in the 5 number size excluding displacement. It is said that the Carrera RS had a touring specification of 1075kg and a sports version of 100kg. It's a bit rough, but imagine a car with a more powerful engine on the current Mazda Roadster. Moreover, the Carrera RS [as well as other 911] was not a so-called "instantaneous wind speed", it was a sports car that could maintain high performance. For example, there were few sports cars at that time that could keep running at 200km/h.

Recently, I have seen some cars that have tuned up RS2.7 and modified to race Carrera RSR specifications that have swept the world's circuits, but the standard Carrera RS is actually an easy-to-use car. If you get used to it, you can even start moving while idling. The reliability is also outstanding. A well-maintained car in good condition will not cause any problems during the summer traffic in Tokyo. An optional cooler was also available, but I have never been in a bad mood even in the heat of human beings making the sound first.

Even after more than 45 years, the Carrera RS2.7 has a solid body without losing its rigidity, direct and rigid, sharp throttle response and highly stable handling, and reliability and toughness that can be used on a daily basis. , Maybe for the first time now it has been legitimately reassessed.
