2023 Volvo V90 Cross Country

Drive-E

2.0L Twin-Charged I4

A supercharger fills in low-rpm boost while the turbocharger takes over up top, eliminating lag and giving roughly 300+ hp from just two liters with seamless, V6-like thrust. The twin-charging makes a small four feel far larger than its displacement.

This twincharged T6 is part of Volvo's Drive-E / Volvo Engine Architecture family, conceived from 2007 as Volvo's break from Ford-derived engines and built around a common 0.5-liter-per-cylinder module. It powers the S90 and V90 flagships.

• The supercharger is clutched and bypassed via a butterfly valve at around 3,500 rpm, then declutched entirely so it stops sapping power once the turbo is in charge.
• Its specific output rivals exotic machinery, prompting comparisons to Ferrari on a power-per-liter basis.
• The whole Drive-E family, from a 1.5-liter triple to 2.0-liter fours, shares the same modular cylinder dimensions and common components.
