Bottom line up front: buy the Porsche 918 Spyder '15 or Koenigsegg Agera RS '15 before February 5, 2026. Both sit at the 977 rating ceiling, cost 3,000–5,000 Gems each, and are the confirmed open-class PvP meta heading into April. Every other class falls at least 49 rating points below — and that gap doesn't close through tuning. The window is open now. It won't stay that way.
What Actually Changed in v1.6.0 (March 2026)
The update consolidates the Car Renewal Plan event structure and tightens the competitive bracket entering Season 7. No pity mechanic, no RNG, no duplicate refunds — you see the car, pay the price, own it. That transparency makes gem planning straightforward.
The Car Renewal Plan direct-purchase shop runs December 25, 2025 through February 5, 2026 (4:59 AM UTC+8).

What Changed Competitively
The 918 Spyder and Agera RS are untouched — no nerfs, no adjustments. Their dominance is structural: the 49-point gap between the top Sports tier (928 rating) and the Extreme floor (977) can't be bridged through tuning alone.
The Bugatti Chiron has been effectively nerfed by context, not code. Its 966 rating sits 11 points below the ceiling, it costs more gems than either 977-rated car, and it loses in open-class matchmaking to both. The 1,603 HP looks impressive. Community consensus is clear: it's a trap pick.
No official nerfs to specific cars are confirmed in v1.6.0 patch notes at time of writing.
Physics and Track Meta
v1.6.0 reinforces a track-type split that's been building for months. Technical circuits with tight corners reward high-torque platforms — that's where the 918 Spyder's 1,280 Nm becomes decisive. Straight-heavy tracks flip toward the Agera RS and its 277.87 mph top speed. Running the wrong car on the wrong track type costs ranked points even when you're both at 977 rating.
Gem Economy System Notes
Two details matter for planning. First, unspent Gems and ECU upgrades carry over post-event — no penalty for banking gems. Second, event-limited cars do not carry over. No confirmed return date exists for the 918 Spyder or Agera RS after February 5. The New Year's Top-Up Bonus Event (best per-gem value this cycle) ended January 18, 2026 — that window is gone.
The April 2026 Season: What You're Preparing For
Season 7 launches with soft demotion mechanics that punish players entering without competitive hardware.
Season 7 Demotion Table
Running a 928-rated Sports car against 977-rated Extreme opponents in open class isn't a recovery strategy — the rating gap compounds the demotion pressure from week one.
Stats That Actually Drive April Outcomes
Three stats determine open-class results: rating (matchmaking bracket), torque (mid-corner stability on technical layouts), top speed (straight-line dominance). HP alone is not a reliable predictor — the Chiron's 1,603 HP is the clearest example of a misleading headline stat.
Based on Season 6 Mayhem Series patterns, April is expected to mix technical circuits with straight-heavy segments. That's exactly why community consensus favors owning both the 918 Spyder and Agera RS — they cover opposite ends of the track spectrum.
Tier List: Best Cars Worth Gems Before April
S-Tier: Buy Before February 5
Porsche 918 Spyder '15 — 977 rating, 882 HP, 1,280 Nm torque, 3,000–5,000 Gems.
The best technical circuit car in the current meta. That 1,280 Nm torque enables mid-corner stability that turbocharged competitors can't match at equivalent rating. If April features tight layouts — and historical patterns suggest it will — this is the highest-priority purchase.
Koenigsegg Agera RS '15 — 977 rating, 1,161 HP, 1,000 Nm torque, 277.87 mph top speed, 3,000–5,000 Gems.
The straight-line king. Less forgiving on technical layouts than the 918 Spyder — it punishes mid-corner errors and rewards precise throttle control. On the right tracks, it's dominant. Experienced players who can manage it will find it decisive.
Owning both costs 7,500–12,500 Gems combined. That's the complete April preparation package.
A-Tier: Strong Value for Class-Restricted Events
McLaren 570S Coupe 2016 — Sports, 909 rating, 570 HP, 600 Nm, 1,500–2,500 Gems.
The top Sports-class pick. Its documented tuning ceiling is well-established: ECU 23332, rev limiter 8,750 RPM, final drive 4.75, brakes 70% balance at 140% pressure, tires 33 PSI front / 28 PSI rear. A fully tuned 570S in a Sports-restricted bracket is genuinely competitive. Don't run it in open class against 977-rated opponents expecting results.
B-Tier: Situational
Lamborghini Aventador SVJ '19 — Extreme, 760 HP, LB834 engine, 3,500–6,000 Gems. Rating unconfirmed at 977. Gem cost overlaps with the 918 Spyder at the high end. Community data is thinner than the flagship pair. Hard to justify as a primary purchase when the 918 Spyder exists at potentially the same price.
Lamborghini Gallardo LP570-4 '11 — Sports, 897 rating, 562 HP, 540 Nm, 1,500–2,500 Gems. Lowest Sports-class rating in the pool. The McLaren 570S outperforms it at the same gem cost. Skip unless you specifically need a second Sports-class car.
Skip List
Bugatti Chiron 2015 — 966 rating, 4,000–6,500 Gems. You're paying a premium to be at a structural disadvantage. Community consensus is unanimous.
Nissan Skyline GT-R R32 '89 — Standard, 802 rating, 800–1,500 Gems. The 175-point gap to the 977 ceiling is insurmountable. Collection only.
Gem-to-Performance Value Analysis
The Chiron's cost-per-rating-point is worse than both 977-rated cars despite costing more. The McLaren looks cheap per rating point — but Sports-class rating points don't translate to open-class competitiveness.
F2P Gem Farming in v1.6.0
Realistic Income Estimate (42-Day Window)
That puts one 977-rated Extreme car at the edge of reachability — but only if you hit every daily and milestone without missing a day. Owning both S-tier cars as pure F2P within this window isn't realistic. Community consensus puts honest F2P Extreme car ownership at 3–7 months of saving without top-up.
One firm rule: use fuel refills only during double-point events. At 50–100 Gems per refill, burning them outside bonus windows is one of the most common gem-drain mistakes in the game.
ECU max upgrades cost 1,000 Diamonds (separate currency) and carry over between seasons — treat these as a parallel long-term investment that doesn't compete with your gem budget.
How to Top Up Efficiently Before April
A 500–2,000 Gem top-up combined with F2P farming puts you at 3,100–5,100 Gems — enough for one 977-rated Extreme car with room for tuning expenses.
The 1,000 + 50 Gems package at S$15.74 (~S$0.015 per Gem) is the best single-purchase value in the SEA region. The bonus 50 Gems makes it the most efficient entry point for light spenders.

Your Gem Spending Decision Tree
0–500 Gems: Don't Buy Cars Yet
Bank everything through February 5. At this level, no Extreme car is within reach this cycle. Consider whether the 1,000+50 Gem package at S$15.74 changes your math enough to reach a 977-rated car before the deadline. Don't spend on Standard or Sports cars for open-class events — the rating gap makes it a waste regardless.
500–1,500 Gems: One Extreme Car Is Reachable
Combined with F2P farming, a top-up puts you at 3,100–5,100 Gems — enough for one 977-rated car. Which one?
Technical circuits, still developing racing line precision → 918 Spyder. The 1,280 Nm torque is more forgiving.
Straight-heavy tracks, strong throttle control → Agera RS. The 277.87 mph top speed is unmatched.
Don't split the budget between an Extreme car and a Sports car. One Extreme car beats two Sports cars in open-class PvP every time.
1,500+ Gems: Full April Preparation
Priority order:
One 977-rated Extreme car (3,000–5,000 Gems) — 918 Spyder or Agera RS based on track preference
Second 977-rated car if budget allows (7,500–12,500 Gems total for both)
McLaren 570S for class-restricted coverage (1,500–2,500 Gems)
ECU upgrades (1,000 Diamonds — parallel investment)
Fuel refills only during double-point events
Skip the Chiron at every budget level. Skip Standard cars entirely for competitive purposes.
Community Verdict
The SEA competitive community is unusually aligned on this update. Both the 918 Spyder and Agera RS are the correct purchases — not because they're flashiest, but because the 977 rating ceiling is a hard competitive wall that tuning can't overcome.
The McLaren 570S is getting more attention than its Sports-class designation suggests. Players in class-restricted formats are finding it delivers strong results at a fraction of Extreme car cost. And here's something most tier lists miss: a fully tuned lower-class car can outperform an untuned higher-class car in class-restricted brackets. Doesn't change the open-class calculus, but a tuned 570S beats an unoptimized 977-rated car in Sports events.
Three recurring regrets from experienced players:
Missing the top-up bonus window. The New Year's event ended January 18. Players who planned to top up later lost meaningful gem value. Bonus windows don't wait.
Buying the Chiron for the HP number. The 1,603 HP is the most seductive misleading stat in the current pool.
Burning gems on fuel outside double-point events. At 50–100 Gems per refill, this drains reserves faster than most players realize until they're short for a car purchase.
FAQ
What are the best cars to buy with gems in v1.6.0? Porsche 918 Spyder '15 and Koenigsegg Agera RS '15 — both 977-rated, both 3,000–5,000 Gems. They're the confirmed meta ceiling for open-class PvP.
Should I save gems or spend before April 2026? Spend — but only on 977-rated Extreme cars before February 5. Unspent gems carry over; the cars don't come back on a known schedule.
Why isn't the Bugatti Chiron recommended despite its high HP? Its 966 rating loses matchmaking bracket advantages in open class, and it costs more gems than both 977-rated cars. High HP doesn't compensate for a structural rating disadvantage.
How many gems can F2P players earn before April? 2,780–4,600 Gems over 42 days (daily missions + milestones) — borderline for one Extreme car at the low end, only if you miss zero days.
918 Spyder or Agera RS — which is better for April? Track-dependent. 918 Spyder (1,280 Nm) wins on technical circuits. Agera RS (277.87 mph) dominates straight-heavy layouts. Own both if budget allows. If choosing one, match it to the track types you play most.
Do gems expire after the event ends? No. Unspent Gems and ECU upgrades carry over. Only the event-limited cars are time-restricted.
