Yes—a three-cylinder car can be genuinely fun to drive. The Ford Fiesta ST and Toyota GR Yaris show why cylinder count alone says little about performance: turbo response, gearing, chassis, weight and driven wheels matter just as much. One prioritizes a lively, usable front-wheel-drive package; the other pairs its three-cylinder engine with more power and four-wheel drive for stronger acceleration and traction.
What makes a three-cylinder car fun?
A three-cylinder engine is a layout, not a verdict on a car’s character. Small displacement can be paired with turbocharging to produce strong output, while the transmission, chassis and tires determine how that power reaches the road. The experience also depends on response and sound: in Auto Express’s road test, the Fiesta ST Edition’s engine pulled strongly from low speeds with minimal turbo lag, and its three-cylinder note was described as bassy. Those are impressions of that car, not qualities guaranteed by every three-cylinder engine.
Ford’s 2017 launch announcement for the next-generation Fiesta ST specified a 1.5-litre turbocharged three-cylinder EcoBoost producing 200 PS and 290 Nm, with 0–100 km/h anticipated in 6.7 seconds. Those were manufacturer launch figures, not results from the later comparison with the GR Yaris. Ford described the engine as combining port and direct fuel injection, turbocharging and variable cam timing. It also said that, under light demand, cylinder deactivation could stop fuel delivery and valve operation for one cylinder, with disengagement or re-engagement in 14 milliseconds. These are Ford’s descriptions of its technology, not independently measured economy results. Ford’s 2017 Fiesta ST announcement also describes selectable Normal, Sport and Track settings that alter engine, steering and stability-control behavior.
Fiesta ST and GR Yaris: two different performance packages
Auto Express compared the Fiesta ST Edition with the GR Yaris and listed their specifications as follows. The figures belong to that comparison; they are not a direct comparison with Ford’s earlier anticipated 0–100 km/h launch time.

| In the Auto Express comparison | Ford Fiesta ST Edition | Toyota GR Yaris |
|---|---|---|
| Engine | 1.5-litre turbocharged three-cylinder | 1.6-litre turbocharged three-cylinder |
| Listed power | 197 bhp | 257 bhp |
| Listed 0–62 mph time | 6.5 seconds | 5.5 seconds |
| Driven wheels | Front-wheel drive | Four-wheel drive |
| Fuel economy in that test | 33.8 mpg | 29.9 mpg |
Auto Express found the Toyota accelerated more strongly and had greater traction when exiting corners. Its four-wheel-drive system helps put power down, while the Fiesta’s front wheels handle both steering and acceleration. In the same comparison, the Fiesta was judged more practical, with more boot capacity and rear-seat space. The result is a useful contrast: the GR Yaris emphasizes pace and traction, while the Fiesta balances brisk performance with everyday usability.
The fuel-economy figures are results from this one comparison, not guaranteed owner figures. Driving style and use can change real-world consumption, and the two cars differ in output and driven wheels; a smaller engine alone does not establish that a car will use less fuel. See Auto Express’s GR Yaris and Fiesta ST Edition comparison for its road-test judgments and specifications.

What the standard Yaris platform can—and cannot—tell you
Toyota’s 2019 announcement about the new standard Yaris is useful context for the broader point that an engine is only part of a car. Toyota described a 1.5-litre inline three-cylinder Dynamic Force engine and said the GA-B platform was 50 kg lighter, at least 30 percent more torsionally rigid and had a center of gravity 15 mm lower than the preceding model. Those are Toyota’s claims for the standard Yaris and its platform, not GR Yaris test results or proof that every Yaris derivative shares the same engine.
Toyota said the standard Yaris engine used high-speed combustion technology to target low fuel consumption and high output. Chief engineer Yasunori Suezawa described pleasurable driving as a development priority alongside efficiency and safety. That statement explains Toyota’s intent; it does not establish an independently verified efficiency ranking. Toyota’s 2019 new-Yaris announcement gives the original platform and engine context.

Which approach suits your kind of driving?
Choose the Fiesta ST character for a usable hot hatch
The Fiesta makes a case for fun that includes ordinary journeys. Auto Express’s test impression of strong low-speed pull and minimal turbo lag points to accessible response, while its reported extra rear-seat and boot space makes it the more practical of the two in that comparison. Its front-wheel-drive layout is a different traction compromise from the Toyota’s four-wheel drive, not evidence that a three-cylinder engine cannot deliver engaging performance.
Choose the GR Yaris character for pace and traction
The GR Yaris’s comparison figures show the quicker car in a straight line, and Auto Express also found it stronger accelerating out of corners. Its higher listed power and four-wheel drive suit a driver who values acceleration and traction over the Fiesta’s reported space advantage. That performance comes with the lower fuel-economy result in this particular test, not a universal ownership forecast.

Are three-cylinder engines powerful enough for a hot hatch?
These examples show that they can be. In Auto Express’s comparison, both cars used turbocharged three-cylinder engines, and the GR Yaris was listed at 257 bhp while the Fiesta ST Edition was listed at 197 bhp. Those numbers describe these specific models; they are not a limit or typical output for three-cylinder cars generally. The broader lesson is that output matters, but so do delivery, traction, gearing, chassis behavior and the car’s intended use.
Availability: the Fiesta ST is now a used-car choice
The Fiesta ST discussed here is not a universally available new-car option. Top Gear says Fiesta production had ended by July 2023 and describes the 2018–2023 ST on the used market. New-car availability varies by market and date, so check local listings rather than assuming a new Fiesta ST can be ordered. Top Gear’s 2018–2023 Fiesta ST review covers that model generation.
