About

Drag Race Sim

Read full description

Drag Race Sim puts you in the rhythm of real drag racing: burnout, pre-stage, bump in, watch the tree, hit your shift points, and run the stripe. Build your garage from a basic starter car into a serious drag racing machine. Tune gearing, tires, power, suspension, and launch setup, then decide how hard to push based on track prep and weather. Every pass gives you a timeslip. Take on a six-chapter career with 36 headline meets, from local race weekends to a national title campaign. Earn licenses, qualify for bigger fields, build sponsor and crew support, and face persistent rivals as the stakes rise. Features: - Real bracket racing flow with dial-ins, reaction time, breakout rules, and win-margin logic - Test passes, qualifying, eliminations, and bracket or heads-up championship routes - A 36-meet career, plus the eight-event short championship - Sponsors, crew, team cars, optional development challenges, and recovery events - Garage progression with parts, dyno feedback, tuning, and car setup choices - Track conditions and weather that matter from pass to pass - Run logs and timeslips for reviewing every pass - Portrait and landscape support outside the race, with racing optimized for landscape This is a racing strategy game as much as a reflex game. The fastest car does not always win. The driver who reads the track, stages clean, cuts a light, and runs the number is the one who survives.

Features
Read full description

Build an engine, bring it to life and keep it in your own pixel-art workshop. Model Engine Builder combines hands-on assembly challenges with engine inspections and an untimed Free Run. BUILD IN FOUR STAGES Fit the parts, tighten the bolts, adjust the setup and time the ignition. Your four stage scores make a build total from 0 to 1000, with online leaderboards. RUN YOUR OWN ENGINE After building, select your engine in the workshop and try Free Run. Control the throttle and engine load, start or stop the engine, and watch its revs, heat and vibration without a time limit. Control and Response inspections are separate scored tests: pass all their segments to earn shelf stamps. Test results and Free Run do not change your build score. 12 ENGINES, 4 READY TO PLAY Four engines start unlocked, including the inline two-stroke twin. The other eight, including the V12, can each be unlocked on this device by completing an optional rewarded ad when available. A one-time, non-consumable Remove Ads purchase unlocks all 12 engines and removes ads. It is not a subscription. Build and run unlocked engines offline without a separate game account. Ads, purchases and online leaderboards require an internet connection; leaderboards may require platform sign-in. Progress is stored on your device. Engine behavior and displayed readings are game approximations, not real engineering measurements.

Verdict

The call

The clearest difference is in-app purchases: Drag Race Sim at none against Model Engine Builder's 1. Drag Race Sim also leads on ads (none vs shown). Model Engine Builder's advantage is update cadence (every 5 days vs every 5 weeks) and iOS requirement (15.6 vs 17.0). On price and device support there is nothing between them.
