Hitting a genuine 100 mph in a radio-controlled car is a different universe from bashing a toy around a parking lot. The machines that actually get there run on high-voltage LiPo batteries, use brushless motors rated for serious power, and demand a wide, smooth stretch of ground — plus a driver with the reflexes to keep them straight. This guide breaks down the two very different ways to approach that speed: a dedicated, track-bred speed machine versus a tougher, more forgiving 4×4 truck that can step up into the 100 mph class.
I’m Min — the founder and writer behind Gadgets Feed. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Whether you crave an 8S aero-tuned rocket or a brushless 4×4 that survives the jumps, here is how to choose the right 100 mph rc car for your skill level and your driving surface.
Our Picks at a Glance
How To Choose The Best 100 MPH RC Car
Hitting 100 mph demands more than a big motor. Battery voltage, gearing, tires, and aerodynamics must work together, and your skill level must match the platform.
Match the platform to your skill level
A speed machine is twitchy and unforgiving; a 4×4 truck is far more stable for beginners. New drivers should start with the tougher 4×4.
Understand what “RTR” really means
RTR models arrive assembled but often require a separate battery and charger. Budget for those extras, as high-voltage packs are a significant cost.

In‑Depth Reviews
1. ARRMA RC Race Car 1/7 Limitless 120 8S BLX Speed Machine RTR w AVC
The pure speed weapon: a 120+ mph machine built for one job, and one job only.
If your goal is to see a triple-digit number on your speed gun, this is the car. The ARRMA Limitless is rated for 120+ mph and runs on up to 8S LiPo packs — the highest-voltage, most extreme setup in this comparison. That 8S capability is the whole point: more cells mean more voltage, and more voltage is what pushes a car past the century mark.
Being “ready to run” means the assembly is done for you — you supply the battery and charger. The factory-finished low-drag body and the tunable aero package (parts you adjust to balance downforce against speed) are included. It spans 36 x 15 x 9.25 inches and tips the scales at 17.9 pounds, so it is a large, dense machine that needs serious open space; a neighborhood sidewalk will not do.
Owners consistently praise the build quality as beautifully crafted. Buyers report: “This car is incredibly fast, beautifully crafted and handles amazingly if experienced enough to handle it.” That last clause is the honest warning — this is emphatically not an entry-level car, and a few new owners hit controller-pairing trouble right from the start.
The verdict: The thing everyone raves about is the quality and the sheer speed potential. This is the crowd favorite for serious speed runners — 4.3 stars across 30+ owners.
Reach for it if: you already know how to handle a fast hobby car and want the real 100 mph experience.
Look elsewhere if: you are new to RC — the sensitivity at this speed will frustrate more than it thrills.
2. Hosim 1/10 RC Truck 4WD Brushless Buggy Cars, MAZEK RTR 62+ MPH
A 4×4 basher that hits 62+ mph from the start and steps into the 100 mph class on 4S.
This Hosim takes the opposite road to speed: it is a tougher, more forgiving 4×4 truck rather than a fragile speed bullet. Its 3670 2850KV brushless motor and 100A ESC (the controller that manages power to the motor, pre-fitted with an aluminum heatsink and cooling fan) deliver 62+ mph on the included 3S pack — that is a 1.9x gap versus the ARRMA’s 120+ mph figure. Slot in a 4S battery, sold separately, and the manufacturer says you open up a true 100 mph class experience.
The included 5000mAh 11.1V 3S battery gives 25+ minutes of runtime, extendable beyond 50 minutes with a spare. Its upgrades over plastic toy trucks are real: an upgraded nylon chassis, CNC-milled metal links, and a chromium steel spiral differential all point to a drivetrain meant to survive big jumps and hard landings on sand, grass, mud, and 45° rock climbs. At 22.83 x 11.81 x 8.26 inches, it is 58% more compact than the ARRMA — far easier to store and toss in a trunk.
Buyers love the speed and value, with steady praise for quality and fun. The honest caveat is durability: it is the most-discussed topic, and the reviews split on it. Owners mention: “Front drive shaft joint broke within the first 5 minutes.” That points to the real trade-off — a few units arrive with a weak spot, and replacement parts are not always quick to get.
What Owners Love
- Genuinely fast and fun from the start on 3S
- Tough metal drivetrain with oil-filled shocks
- Strong value for a hobby-grade 4×4
The Reality Check
- Durability gets mixed feedback — the shaft joint is a known weak point
- Parts availability can be slow, so keep spares on hand
- Large batteries may need mounting mods to fit
Pick this if: you want one truck that bashes hard on 3S today and can chase the 100 mph class on 4S later.
Think twice if: you expect flawless durability or will be upset by the occasional broken part; stick to the ARRMA for pure speed purity.
Understanding the Specs
Battery Voltage (S-Count)
The “S” number tells you how many cells are wired in series inside a LiPo pack, and each cell adds about 3.7 volts. More cells mean more voltage, and more voltage is the fastest path to a higher top speed. The ARRMA runs up to 8S; the Hosim ships on 3S and is rated for 4S.
Brushless Motor KV Rating
KV measures roughly how many RPM the motor spins per volt. A higher KV like 2850KV wants lower voltage; pairing it with the right battery keeps the drivetrain from being overstressed. It is the balance between motor, voltage, and gearing that decides your real top speed.

Final Thoughts: The Verdict
For most users chasing a true 100 MPH RC Car, the winner is the ARRMA Limitless 120 because it is the only one rated for 120+ mph outright on an 8S pack, with the aero tuning and build quality that serious speed runners expect. If you want a tougher, more versatile machine that bashes off-road today and can reach the 100 mph class later, grab the Hosim MAZEK M23. And if you are still learning, the Hosim’s forgiving 4×4 chassis is the one to reach for before you ever strap in an 8S rocket.
