As part of Caddy's V-series, the CTS-V Sport Wagon is lugged around by the 6.2-liter supercharged V8 engine found in all the other CTS-V models. It wasn't detuned or tamed down to fall inline with its more domestic body type. It still pushes out 556hp (and 551 lb-ft of torque) to the rear wheels. That massive figure is thanks in part to the intercooled Eaton Twin Vortices Series. It's a high-tech system that delivers more efficient and smoother airflow to the engine for better power delivery and gas mileage.
