How Turbocharging changed Porsche forever

The naturally aspirated flat-six has always had a special place in the hearts of Porsche purists. If the engine is cooled by God’s good air, then it is even more heartwarming. The connection between man and machine is just more pure without forced induction.

To fully understand what has led to the latest turbocharged Porsches, you have to go all the way back to the late ’60s.

Turbos Give Small Car Engines a Big Boost

Turbochargers have been used on race cars for decades. They’re also commonly used on heavy-duty trucks to improve operating efficiency and on sports cars to add extra power.

But, turbochargers are starting to appear under the hood of more mundane passenger cars. That’s because the devices are a cost-effective way to improve fuel efficiency. Turbos can help a four-cylinder engine produce as much power as their bigger V-6 counterparts.

It’s part of an ongoing trend toward engine downsizing. Automotive engineers are eager to harness the advantages of turbo technology to improve fuel efficiency and reduce emissions.

Why Cars Are Moving to 48-Volt Electrical Systems

Many cars will soon have 48-volt electrical systems. They’ll power stop-start motors, hybrid motors, and turbochargers, allowing for smaller engines with better fuel economy and performance.

They’ll handle accessories ranging from mechanical or hydraulic power to electric power such as power steering, power brakes, water pump, radiator cooling, and air conditioning.

These will be combination 12- and 48-volt systems with 12 volts for traditional lighting and infotainment, 48 volts for more power-hungry components.
