The latest update has given players plenty of reasons to revisit their garages in Forza Horizon 6. Update 6 introduces new engine swaps for several existing vehicles, opening up fresh tuning possibilities and making previously overlooked cars more competitive. For players looking to improve their collections and experiment with different builds, understanding these changes can make Forza Horizon 6 Credits more valuable when deciding which vehicles and upgrades deserve investment. Beyond the officially announced additions, there are also hidden customization changes that could influence how players approach online racing.

Mazda 787B and Furai: Unusual Engine Swaps Deliver Surprising Results

One of the most interesting aspects of Update 6 is the new engine-swap options for the Mazda 787B and Mazda Furai. At first glance, these swaps seem counterintuitive because they can reduce a vehicle's power and Performance Index (PI). However, lowering a car's performance rating can create opportunities to build a more competitive setup within a specific class.

The Mazda 787B demonstrates this approach particularly well. By installing the alternative engine, players can reduce its power and then adjust the drivetrain and tires to bring the vehicle into a more suitable class. Adding all-wheel drive and experimenting with tire compounds can produce a dramatically different result from the original configuration.

The centrifugal supercharger is another important part of the equation. In one tested configuration, it adds approximately 64 horsepower without increasing torque, while adding a small amount of weight and changing the vehicle's PI. Although more horsepower does not automatically translate into faster lap times, the combination of engine choice, drivetrain, tires, and performance rating can create a powerful racing build.

The Mazda Furai follows a similar principle but offers exciting possibilities in the S2 class. Its V6 engine swap, combined with a centrifugal supercharger and high-grip tires, can deliver impressive performance. Early testing suggests that both Mazdas can challenge established competitors, although their ultimate positions in the competitive meta still require further testing.

Ginetta Models Remain Fast but Require a Different Driving Style

The Ginetta lineup is another major part of the current racing discussion. These vehicles offer tremendous grip and stability, allowing drivers to maintain high speeds through many corners. However, that stability comes with a trade-off: some setups feel less agile and may experience understeer in tighter sections.

For drivers who prefer responsive cars that rotate quickly through corners, the Ginetta may take some adjustment. Its strong grip encourages early acceleration, but pushing too aggressively in the wrong corner can expose its handling limitations.

Despite these drawbacks, Ginetta vehicles remain highly competitive in S1 and S2. Their performance illustrates why vehicle balance cannot be measured by horsepower alone. Tire width, weight, handling characteristics, and the ability to maintain speed through corners all contribute to a successful build.

Nissan VQ Engine Swaps Give the GT-R New Potential

Update 6 also introduces Nissan VQ engine options for several Nissan vehicles and certain Lexus models. These additions could be particularly significant for players who have struggled to make some Nissan cars competitive in previous configurations.

The Nissan GT-R is a notable example. Historically, some GT-R builds have struggled to compete with stronger alternatives in Horizon racing. The new engine options provide another way to lower its class rating and rebuild its performance around a different combination of power, tires, and drivetrain upgrades.

Testing against a Chevrolet Camaro suggests that the GT-R can be surprisingly effective. Its braking and cornering performance can help it gain an advantage through technical sections, although the car may feel slippery and less forgiving than some rivals. Drivers will need to learn its handling characteristics rather than assuming that its increased performance will make every race easy.

The broader lesson is that engine swaps can make previously overlooked vehicles worth reconsidering. Instead of relying on a small group of familiar cars, players may now have more opportunities to develop competitive builds around their personal favorites.

Hidden Tire Upgrades Expand Customization Options

Not every change introduced with Update 6 appears in the official patch notes. Several vehicles have reportedly received additional tire options, including the Hennessey Venom, Ferrari SF90, and Lamborghini Centenario.

Depending on the vehicle, players may find alternatives such as semi-slick tires, racing slicks, or softer-compound tires. These options can improve grip and provide more flexibility when tuning a car for particular racing conditions.

However, additional grip does not always mean a better overall build. Some tire compounds are less efficient in terms of Performance Index, meaning the improvement in cornering ability may come at the expense of other performance advantages. Players should compare different configurations instead of automatically selecting the tire with the highest grip.

These discoveries also highlight the value of exploring customization menus after major updates. Even small changes to available parts can open up new tuning strategies, particularly for players who enjoy experimenting beyond the most obvious upgrades.

The Jeep Gladiator Becomes an Unexpected Contender

Perhaps the most surprising example is the Jeep Gladiator. With the Dodge Viper's V10 engine swap, a centrifugal supercharger, off-road tires, and all-wheel drive, the truck can become a formidable performer despite its considerable weight.

One tested configuration reaches approximately 880 horsepower. The V10 provides a substantial power increase, while the supercharger adds even more performance for a relatively modest PI cost. Its low rev limit remains a disadvantage, but the Gladiator's stability and traction help compensate for its weaknesses.

A vehicle that previously struggled to compete can now deliver respectable results in suitable conditions. This transformation demonstrates how much a carefully chosen engine swap can change a car's identity and practical usefulness.

Better Balance Matters More Than Simply Adding Cars

The biggest takeaway from Update 6 is not that the Mazda 787B, Furai, Nissan GT-R, or Jeep Gladiator has definitively become the best car in its class. The update is still relatively new, and competitive players need more time to test these configurations across different tracks and racing conditions.

Instead, the changes appear to be expanding the number of viable choices. Rather than allowing one vehicle to dominate every event, the game now offers more potential contenders with different strengths and weaknesses. That variety can make online racing more interesting because success depends on vehicle selection, tuning knowledge, and driving skill.

For the long-term health of Forza Horizon 6, improvements to online balance and the introduction of ranked racing could be more valuable than simply adding more vehicles or cosmetic body kits. Players who enjoy competitive racing need meaningful reasons to experiment and improve, not just a larger garage. Exploring these new builds and making smart upgrade decisions can also help players get more from FH6 Boosting for sale as they work toward a more competitive online experience.
