MG4 XPower Accessory Pack Review: Affordable Performance Upgrades
MG4 XPower Accessory Pack: Performance Bargain or Missed Opportunity?
Imagine owning the fastest accelerating new car under $60,000 - the MG4 XPower rockets to 100km/h in 3.8 seconds. But what if you could enhance its looks and handling with factory-warranted upgrades? After testing MG's prototype accessory pack, I've discovered exactly how these proposed modifications transform the driving experience. This analysis reveals whether these dealer-fit upgrades deserve a place in showrooms.
What's Included in MG's Proposed Upgrade Package
MG's accessory pack centers on three key modifications that address the standard XPower's visual and dynamic shortcomings. Lowered H&R springs reduce ride height by 30mm, significantly altering the car's center of gravity. Combined with new 18x8.5-inch Conic flow-form wheels, these changes substantially impact handling dynamics. The third element is a comprehensive body kit featuring front splitters, side skirts, and rear diffuser elements.
What makes this proposal unique is MG's warranty approach. While the full car enjoys a 10-year factory warranty, these accessories would carry a 12-month manufacturer-backed guarantee when installed through dealers. As MG product planner James Copley confirmed to Drive.com.au: "We're validating whether customers value factory-approved modifications over aftermarket solutions." This warranty safety net could reassure buyers hesitant about voiding their new car coverage.
Real-World Driving Impressions: Beyond the Spec Sheet
The lowered suspension delivers noticeable cornering improvements but reveals chassis limitations. Through winding roads, body roll reduces by approximately 15% compared to the standard XPower. However, the unchanged dampers struggle to control rebound over sharp bumps, creating a slightly unsettled feel. Urban driving exposes the kit's compromise - while generally compliant, the 30mm drop causes occasional scraping on steep driveways.
The wheels and tires present a significant performance mismatch. Despite the Conic alloys' sporty appearance, MG retains the standard Bridgestone Turanza T005 rubber - the same tires used on base model MG4s with half the power. During hard acceleration, torque steer remains pronounced as these economy-focused tires struggle to harness 600Nm of instant torque. Fitting proper performance rubber like Michelin Pilot Sport 5s would transform grip levels.
Surprisingly, the visual changes impact perception more than performance. The body kit's carbon-fiber-look elements add aggression, though some details like the "sporty" badges feel tacky. More importantly, the package doesn't address the XPower's core dynamic weaknesses: the artificial steering feel and brake caliper covers that disguise modest actual hardware.
Critical Upgrades MG Should Consider Adding
Based on my testing, MG should expand this package to address three critical shortcomings. First, performance brake upgrades are essential - the current 345mm discs fade noticeably during repeated hard stops. Second, the Alcantara seats lack sufficient bolstering for spirited driving. Recaro sport seats would keep drivers planted. Finally, MG must offer tire upgrades; the Turanzas are dangerously inadequate for 320kW.
When comparing rivals, the BYD Seal Performance matches the MG's acceleration but lacks the hot hatch ethos. The Cupra Born handles beautifully yet costs $20,000 more. This context makes MG's value proposition compelling, but the accessory pack needs refinement. As automotive engineer David Taylor observed: "The fundamentals are strong, but the execution needs more performance integrity to match the power figures."
Owner's Action Plan: Evaluating the Upgrade Kit
Before considering this package, complete these essential steps:
- Measure your daily route's steepest inclines to assess clearance issues
- Budget for premium tires immediately - the Turanzas compromise safety
- Test drive both standard and modified XPowers back-to-back
- Verify final warranty terms in writing before purchase
- Negotiate installation costs upfront - dealers may charge $1,500+ for fitting
For serious enthusiasts, I recommend these supporting upgrades beyond MG's package:
- Brake Pads: EBC Redstuff pads ($350) improve stopping power without full brake replacement
- Tires: Michelin Pilot Sport 5 ($1,800/set) transform grip and handling balance
- Alignment Kit: SuperPro caster increase bushes ($220) sharpen turn-in response
The Verdict: Style Over Substance
This accessory pack enhances aesthetics more than performance - the visual transformation is significant, but dynamic improvements are marginal. At $4,400 plus fitting, it represents reasonable value for the warranty coverage alone. However, until MG addresses the tire and brake shortcomings, the package feels incomplete. For now, I'd install the springs for better cornering and source aftermarket wheels separately.
