When you think of the humble (Thai and Indian market) Honda City, images of efficient urban commuting or standard one-make control racing usually come to mind. But at the recent Songkhla Grand Prix, the engineering minds at TTR (Terra Engineering) and Grand Prix Motorsport completely rewrote the rulebook.
Unveiled as a prototype during the event’s time attack sessions, this heavily modified 2026 Honda City is essentially a TCR-style touring car on absolute steroids. Far from a basic track-day special, this wild machine previews the aggressive next-generation evolution of Honda’s one-make racing series.
At the heart of it is a production-based 1.0-litre turbocharged three-cylinder engine. While standard control cars make do with modest power, this prototype is dialled up to a staggering (for a 1.0L) 209kW. Even more impressive is the target weight.
While the current manual-transmission race cars hover around 1100 kg, this project is aiming for a feather-light 950 to 980kg. Paired with the power bump, the power-to-weight ratio transforms the mild-mannered sedan into a genuine circuit weapon.
The exterior styling immediately draws attention, featuring a proper widebody setup that pushes the stance out by up to 5cm on each side, with lightweight 17-inch racing rims wrapped in 225/45 tyres. High-performance Neotech brake calipers sit behind the rims with vented and slotted discs.
Up front, a motorsport-grade splitter with integrated anti-dive plates dominates the lower fascia. However, the visual standout is the cut steel bonnet housing a custom aluminium cooling exit, funnelling heat straight off the massive front-mounted intercooler setup.
Inside, the cabin has been stripped bare to accommodate a custom-built roll cage, an F1-style carbon steering wheel with paddle shifters, a MaxxECU setup, and a Sparco racing bucket seat. For motorsport fans craving the return of open-class development, this wild Honda City prototype is a welcome dose of insanity. Check out the video below for more.
