American tuner APR has revealed its latest performance upgrades for the seventh-generation Volkswagen Golf GTI, handing the German hot hatch a substantial increase in power and a soundtrack to match.

Churning out 169 kW and 350 N.m of torque as standard, 2,0-litre turbocharged four-banger has been tweaked to send a whopping 296 kW and 546 N.m to the front axle via its six-speed dual-clutch transmission. That's 83 kW and 176 N.m more than the Golf GTI TCR (which has been confirmed for local shores) and 68 kW and 146 N.m more than the four-wheel-drive Golf R, which we tested earlier in 2019.

The aforementioned package does, however, require the use of 104 octane fuel. Fortunately, a 295 kW and 522 N.m version is also on offer, which is perfectly happy running on 93 unleaded.

According to APR, the substantial power increase has been achieved by equipping the hot hatch with an uprated turbocharger with a new intake, as well as a revised intercooler and a catback exhaust. As an option, the latter can be specified with three sound modes for “more aggressive pops and bangs” than the stock set-up.

In addition, the firm has fitted a Kistler in-cylinder pressure transducer system, which improves combustion efficiency and reduces in-cylinder combustion pressure. It has also remapped throttle response for a more linear power delivery and, thanks to special software, wheel spin has apparently been reduced.

The Alabama-based company has yet to announce what influence these modifications have on the GTi's top speed and its 0-100 km/h sprint time.
