Why doesn't Yamaha produce cars?

[TheoFitz]

Yamaha has not ventured into the automotive industry primarily due to Toyota Motor Corporation, its second-largest shareholder. In the early days, as Toyota continuously invested in Yamaha, Yamaha stated that it would not genuinely enter the automotive sector. To avoid commercial conflicts, Toyota required Yamaha to sign an agreement long ago, prohibiting Yamaha from entering the car manufacturing industry, or else face substantial penalty fees. Here are some cars equipped with Yamaha engines: 1. Toyota AE86: The AE86 was powered by a 1.6L naturally aspirated engine, model 4A-GE, which was designed by Yamaha. This 1.6L engine could deliver a maximum power of 121kW and a peak torque of 165Nm, with a peak engine speed of up to 8000 rpm. Later, a 20-valve (5 valves per cylinder) racing version of the 4A-GE was developed, which was the engine replaced after Takumi's first engine blowout in "Initial D." This engine's peak speed reached a staggering 12000 rpm. 2. First-generation Ford Taurus-SHO: The late 1980s Taurus-SHO was equipped with a 3.0L naturally aspirated V6 engine, model SHOV-6. This engine, capable of producing 164kW maximum power at 6200 rpm, brought a fresh breeze to the American performance car scene at the time.
