Quick Answer: Racing Master 26S1 SEA launched February 2026, featuring the Bugatti Chiron 2015 (966 rating, Extreme class) and Lamborghini Aventador SVJ as the season's top gem targets. The Car Renewal Plan Extreme Group costs 3,000–5,000 gems. The best-value bundle is 1,000+50 Gems at S$13.72 (24.9% discount). Chiron ECU max upgrade requires 1,000 Diamonds and 100 Stage 04 ECU Blueprints.
Why 26S1 SEA Is a Critical Gem Window
Three major events share the same hard deadline — February 5, 2026:
Speed Era Limited Expo — January 1 to February 5, 2026
Aventador SVJ acquisition event — December 18, 2025 to February 5, 2026
Car Renewal Plan — December 25, 2025 to February 5, 2026
Miss that cutoff and you lose every gem-efficient acquisition path for both cars. Blueprint draws, Expo packs, and discounted renewal bundles all disappear — with no guaranteed rerun.
Why Chiron 2015 and SVJ Are the Top Targets
The Bugatti Chiron 2015 sits at a 966 performance rating (Extreme class), producing 1,603 HP and 1,600 Nm from its WR16 8.0L turbocharged engine. At MAX tuning: 1,922 HP at 1,868 kg curb weight — top-tier 26S1 numbers.
The Lamborghini Aventador SVJ (LB834 2019) also occupies Extreme class, making it the second essential Extreme-tier asset this season.
Both cars are irreplaceable in Knockout Mode, where 32-player eliminations narrow to 8-player finals and raw performance ratings directly influence bracket outcomes.
Racing Master 26S1 SEA Gem Economy: The Foundation
How Gems Are Spent
Gems fund everything simultaneously:
Car unlocks via Expo packs and blueprint draws
Car Renewal Plan tiers
Fuel refills (50–100 gems each)
Tuning upgrades
The Renewal Plan has three tiers:
Standard Group: 800–1,500 gems
Sports Group: 1,500–2,500 gems
Extreme Group: 3,000–5,000 gems
Targeting both Chiron and SVJ means operating exclusively in the Extreme Group bracket. Map your total budget against the 5,000-gem ceiling plus tuning reserves before spending a single gem.
Best Gem Bundles for SEA Players
70+4 Gems — S$1.08 (standard S$1.26), ~USD 0.84
350+18 Gems — S$5.52 (standard S$6.34)
1,000+50 Gems — S$13.72 (standard S$18.42) — 24.9% discount, best value
Weekly Card — S$1.05–S$1.26 for daily gem drip
Monthly Card — S$2.43–S$2.91 for sustained passive accumulation
The 1,000+50 bundle is the clear efficiency winner. Three bundles = 3,150 gems at S$41.16 — enough to enter the Extreme Group floor with gems left for fuel and minor upgrades.

Bugatti Chiron 2015: Full Gem Cost Analysis
Unlock Paths
The primary path runs through the RM Auto Expo Bugatti Chiron Blueprint draw system. Expo packs purchased with gems yield Gold keys for blueprint draws. This is generally more gem-efficient than direct unlock for players who commit to consistent draws during the Speed Era Limited Expo (January 1 to February 5, 2026).
The Car Renewal Plan Extreme Group (3,000–5,000 gems) is the alternative structured path — ideal for players who've accumulated free event blueprints and need to close the gap before the deadline.
Total Gem Budget: Chiron 2015 Unlock + Full Tuning
Extreme Group Car Renewal Plan: 3,000–5,000 gems
ECU max upgrade: 1,000 Diamonds
Stage 04 ECU Blueprints: 100 required
Fuel refills during grind phases: 300–500 gems
Expo pack draw reserve: 500–1,000 gems
Estimated total: 4,000–6,500 gems for a fully competitive Chiron 2015 build.
Chiron 2015 Tuning Priority Order
Don't skip ahead to Gold enhancements — it's the most common gem-wasting mistake in 26S1 SEA.
ECU upgrade to maximum — 1,000 Diamonds unlocks the full WR16 power ceiling
Stage 04 ECU Blueprints — 100 blueprints required; complete before any cosmetic upgrades
Suspension calibration — Turbo pressure 1.10 atm, camber -4.5° front / +0.5° rear
Brake and tire setup — 70% brake balance pressure, 33 PSI front tire, 28 PSI rear
Gold enhancements — Apply only after core mechanical upgrades are complete
Lamborghini Aventador SVJ: Full Gem Cost Analysis
Unlock Paths
The SVJ event ran December 18, 2025 to February 5, 2026. Gems purchase Expo packs → Gold keys → blueprint draws targeting the SVJ. Players who joined from December 18 have a significant blueprint head start.
Late entrants: the Car Renewal Plan Extreme Group (3,000–5,000 gems) is the most reliable completion path before February 5.
Total Gem Budget: SVJ Unlock + Competitive Tuning
Expo pack draws (Gold key acquisition): 1,000–2,000 gems (draw-dependent)
Car Renewal Plan Extreme Group (if needed): 3,000–5,000 gems
Tuning upgrades post-unlock: 500–1,000 gems
Fuel refills during event grind: 300–500 gems
Estimated total: 3,500–6,000 gems for a competition-ready SVJ.
Aventador SVJ Tuning Priority
Engine upgrades first — maximize base power before addressing handling
Aerodynamics second — critical for high-speed stability in Knockout Mode finals
Nitro system third — timing and capacity upgrades deliver the most consistent lap time gains
Suspension last — fine-tune after core performance parts are locked in
Chiron 2015 vs. Aventador SVJ: Which Gets Gems First?
The Chiron 2015 holds a clear statistical edge: 966 rating, 1,603 HP base, 1,922 HP at MAX. On high-speed circuits and straight-line dominant tracks, it's the stronger investment.
The SVJ offers a more accessible acquisition path through its dedicated event structure. For limited gem budgets, the SVJ event may deliver a competitive Extreme-class car at lower total gem cost than a full Chiron build.
Verdict:
Prioritize Chiron 2015 — if you compete in Knockout Mode and high-speed circuits where the 966 rating and 1,922 MAX HP create decisive advantages
Prioritize Aventador SVJ — if you joined the December 18 event early and have accumulated blueprints; completing it first costs fewer additional gems
Two-car players — allocate gems to whichever car is closest to unlock threshold first, then redirect remaining budget to the second

Smart Gem Allocation: Avoiding Waste in 26S1 SEA
Two-Car Budget Framework
Combined gem budget for both cars: 7,500–12,500 gems (both Extreme Group Renewal Plans + tuning + fuel reserves). At S$13.72 per 1,000+50 bundle, that's approximately S$96–S$165 at maximum efficiency.
Supplement top-up spending with every free gem source available:
New Year's Top-up Bonus (January 1–18, 2026) — bonus gems on qualifying top-ups
Gem 10-draw Snowfall Memories (January 2–29, 2026) — draw-based gem rewards
Champion Driver ranked rewards — minimum 1,200 points earns 200-point reset reduction
Ace Driver tier — minimum 1,000 points with 200-point reset reduction
5 Gem-Wasting Mistakes to Avoid
Spending on non-Extreme class cars first — Standard and Sports Group cars don't compete in the same ranked brackets
Buying 70+4 bundles repeatedly instead of 1,000+50 — smaller bundles cost proportionally more per gem
Maxing Gold enhancements before ECU — ECU delivers larger performance gains per gem spent
Ignoring fuel refill costs — unplanned refills at 50–100 gems each can consume 500+ gems from your tuning budget
Waiting until the final week — early starts statistically reduce total blueprint acquisition cost via draw RNG
Blueprint Farming to Cut Costs
Active participation in the Speed Era Limited Expo (January 1 to February 5, 2026) generates blueprint draws without direct gem expenditure. Every free blueprint acquired reduces paid Expo pack draws needed — directly lowering total gem investment for both cars.
Frequently Asked Questions
How many gems do I need for both Chiron 2015 and Aventador SVJ in 26S1 SEA? Plan for 7,500–12,500 gems total — covering both Extreme Group Renewal Plans (3,000–5,000 gems each) plus tuning and fuel reserves. The 1,000+50 bundle at S$13.72 is the most cost-efficient accumulation method.

Is the Aventador SVJ worth unlocking with gems in 26S1 SEA? Yes. It's Extreme class with a dedicated event path until February 5, 2026. Players who started December 18 can complete it at lower gem cost than a full Chiron build — strong secondary target.
How do I top up Racing Master SEA gems safely via BitTopup? Tap Avatar in-game → find Role ID → select bundle on BitTopup → enter Role ID → complete payment → check in-game mail within 60 seconds. Gems arrive in 10–30 seconds. No account credentials required.
Should I prioritize ECU or Gold enhancements first for the Chiron 2015? Always max ECU first. It requires 1,000 Diamonds and 100 Stage 04 ECU Blueprints, and unlocks the full 1,922 HP ceiling. Gold enhancements before ECU completion deliver significantly lower performance returns per gem spent.
Can I still unlock the Aventador SVJ after February 5, 2026? The confirmed event window closes February 5, 2026. Post-deadline availability is unconfirmed — future reruns aren't guaranteed. Complete acquisition before the deadline.
