Based on the HQ revision of the second generation Monaro, the GTS 350 was designated as the top-of-the-line model with a 350 ci (7.0 litre) V8 engine.
The HQ Monaro is considered one of the most attractive body designs to ever come from Australian manufacturer Holden. American muscle car enthusiasts may even mistake the Monaro for a Pontiac GTO. While there may be similarities, the Monaro is unique to the island continent. As the moniker suggests, a GTS 350 has a 350-cubic-inch Chevrolet V8 under the hood. The HQ was something of a last gasp for the muscle car status the Monaro had attained. The HQ’s bold striping spoke to an aggressive nature that was all-too-short lived. In later years, Holden would de-emphasize performance, eliminate the availability of a manual transmission, and, eventually, discontinue the 350. Still, in its time, the GTS 350 was one of the kings of the Australian road.
The GTS 350 is based on a somewhat front-heavy rear-wheel drive platform that weighs 3150 lb (1429 kg). With a 275 hp (205 kW) 5.7 litre V8 engine and 4-speed manual transmission, it is able to reach 135 mph (218 km/h) as top speed.

The 5.7 litre V8 engine gives the GTS 350 decent acceleration, although it does suffer from its long 4th gear when going uphill. Due to a slow steering and sluggish suspension, the GTS 350 may prove to be handful in corners.
With the S1 upgrade preset, the GTS 350 receives a significant power bump from a 6.2 litre V8 engine that produces 1014 hp (756 kW) and 841 ft·lb (1140 N·m) of torque. As a result, its rear tyres often become overwhelmed by the excessive torque output. Neverthless, the GTS 350 does feature strong grip performance that can only be achieved with proper throttle management.
In Forza Horizon 3, the GTS 350 reaches S1 as its maximum performance class with the auto-upgrade feature, but is able to reach S2 with conversion upgrades.
