Is the 2013 BMW 328i twin turbo?

The 2013 BMW 328i is turbocharged, but it does not use two separate turbochargers. It employs a single turbocharger with a twin-scroll design, BMW’s TwinPower Turbo branding, delivering about 240 horsepower and 260 lb-ft of torque.

Engine and turbo architecture

Under the hood, the 328i is powered by the N20 2.0-liter inline-4 turbo engine. The turbo is a single unit with twin-scroll technology, which helps shorten turbo lag and improve efficiency compared with older, single-entry turbo designs. This setup is marketed by BMW as TwinPower Turbo rather than as a true twin-turbo system.

Key specifications of the N20 engine

• Displacement: 2.0 liters


• Configuration: Inline-4


• Turbocharger: Single turbo with twin-scroll design


• Power output: 240 hp


• Torque: 260 lb-ft


• Fuel system: Direct injection


• Transmissions: 6-speed manual or 8-speed automatic


• Drivetrain options: Rear-wheel drive standard, optional xDrive all-wheel drive

BMW’s branding calling this setup “TwinPower Turbo” refers to the turbocharging technology and coil-on-plug efficiency enhancements, not to a system with two separate turbochargers.

How it compares to other 3-series turbo configurations

For context, the 3-series lineup around this era offered different turbo configurations. Here’s a brief comparison to help distinguish them:

• N20 2.0L turbo inline-4 (328i) — single turbo with twin-scroll, 240 hp.


• N55 3.0L turbo inline-6 (335i) — single turbo with twin-scroll, typically around 300 hp; still marketed as TwinPower Turbo.


• N54 3.0L turbo inline-6 (older 335i, prior to N55) — twin-turbo (two turbos) configuration, around 300 hp.


• B58 3.0L turbo inline-6 (later models like 340i) — single turbo with twin-scroll, higher output in later years.

In short, if you’re specifically asking about two separate turbochargers, the 2013 328i does not use a twin-turbo setup. It uses a single turbocharger with a twin-scroll design, grouped under BMW’s TwinPower Turbo branding.

Bottom line

Yes to turbocharging, no to two turbos. The 2013 BMW 328i relies on a single twin-scroll turbocharger (N20) rather than a pair of turbochargers, and BMW markets this as TwinPower Turbo.

Summary

The 2013 328i employs a 2.0-liter inline-4 turbo engine with a single twin-scroll turbocharger, producing about 240 hp and 260 lb-ft of torque. It offers RWD as standard with optional xDrive and transmissions including a 6-speed manual or an 8-speed automatic. This setup is distinct from true twin-turbo configurations found in some earlier models, and BMW’s branding emphasizes turbocharging technology rather than the number of turbo units.
