VW ID. Polo, ID. Cross, Epiq & Raval: 80% Shared Parts

Volkswagen Group is taking component sharing to a new level with four upcoming electric cars. The Volkswagen ID. Polo, ID. Cross, Škoda Epiq and CUPRA Raval share more than 80% of their components, despite their different designs and brand identities.

Developing four vehicles around the same technical architecture can significantly reduce manufacturing and development costs. But it also raises an interesting question for future owners: could a faulty shared component cause similar problems across several different models?

According to Volkswagen Group's official announcement on 11 October 2026, the four vehicles form part of the company's Electric Urban Car Family project, which is designed to combine greater technical commonality with distinctive styling.

Volkswagen says its group-wide approach is expected to deliver savings of around €600 million.

Four Electric Cars, One Platform: What Do They Share?

The Volkswagen ID. Polo, ID. Cross, Škoda Epiq and CUPRA Raval have been developed around the Volkswagen Group's updated MEB+ electric vehicle platform.

Although the vehicles share a substantial proportion of their components, they are designed to appeal to different buyers.

The ID. Polo is positioned as a compact electric car intended for everyday urban driving, while the ID. Cross brings an SUV body style to the same family.

The Škoda Epiq focuses on practicality and everyday usability, whereas the CUPRA Raval aims to offer a sportier appearance and driving character.

Despite their different designs, the four models benefit from shared engineering, electric vehicle architecture and numerous common components.

However, sharing more than 80% of their parts does not mean that all four cars use identical batteries, electric motors or software configurations. Technical specifications can differ between models and versions.

Could 80% Shared Components Lead to Common Faults?

This is perhaps the most interesting question from an ownership perspective.

When several vehicles use the same electronic control unit, mechanical component or software version, a defect affecting that particular component could potentially appear across more than one model.

For example, if a shared control module develops a hardware problem or a common software version contains an error, different vehicles using the affected component could experience similar symptoms.

However, component sharing also offers potential advantages.

Producing parts at greater scale can help manufacturers refine production processes, improve parts availability and develop solutions that can be applied across multiple vehicles.

A problem discovered in one model might also be identified and addressed in related models before it becomes widespread.

There is currently no confirmed common chronic defect affecting all four of these new electric vehicles.

It would be premature to make claims about their long-term reliability before sufficient real-world ownership data becomes available.

Volkswagen Has Faced Infotainment Software Problems Before

A previous Volkswagen recall illustrates why the reliability of shared electronics and software deserves attention.

In May 2024, Volkswagen announced a US safety recall affecting certain 2021–2023 ID.4 vehicles under NHTSA campaign 24V344.

According to the official NHTSA recall report, certain software faults could cause the instrument cluster or central infotainment display to fail to start properly or unexpectedly restart.

In some circumstances, drivers could temporarily lose access to important information, including the speed display or reversing camera image.

The recall covered approximately 80,000 ID.4 vehicles, with Volkswagen planning software updates to address the problem.

However, this distinction is essential: the issue was documented in earlier ID.4 models, not in the new ID. Polo, ID. Cross, Epiq or Raval.

It is not evidence that the four upcoming models will suffer from the same fault.

Instead, it provides a real-world example of why software and electronic component reliability matter in modern electric vehicles.

Do All Four Cars Use the Same Battery? The Škoda Epiq Example

A shared platform does not necessarily mean identical battery technology across every vehicle or trim level.

The Škoda Epiq provides a useful example.

According to Škoda's official technical documentation, the Epiq range includes different battery configurations using both lithium iron phosphate (LFP) and nickel manganese cobalt (NMC) cell chemistry.

LFP and NMC batteries differ in their chemical composition, energy density and other operating characteristics.

Consequently, even vehicles developed around the same platform may have different battery behaviour and long-term ownership characteristics.

Whether a particular battery defect could affect another model depends on the actual cells, modules, production batches and electronic management systems involved.

It cannot be determined from platform sharing alone.

Volkswagen Targets €600 Million in Savings and Uses AI in Vehicle Design

Volkswagen Group's strategy extends beyond common mechanical and electronic parts.

The manufacturer says its group-wide engineering and design synergies are expected to deliver approximately €600 million in savings, while allowing each brand to maintain a distinctive identity.

That does not mean customers will automatically receive a €600 million reduction in vehicle prices. The figure concerns the group's development and operational efficiencies.

Volkswagen is also introducing internally developed artificial intelligence tools into its design processes.

These systems can transform designers' sketches into photorealistic images and videos, helping teams visualise and refine ideas more quickly.

According to Volkswagen, AI-supported workflows can reduce the time and costs associated with certain design activities by approximately one-third.

The overall objective is to develop vehicles more efficiently without making every Volkswagen, Škoda and CUPRA look or feel identical.

Drivisual Verdict: Different Brands, Shared Engineering

The fact that the Volkswagen ID. Polo, ID. Cross, Škoda Epiq and CUPRA Raval share more than 80% of their components highlights how important economies of scale have become in the affordable electric car market.

For customers, this approach could offer advantages through more efficient development, greater component availability and potentially lower production costs.

There is, however, another side to the equation.

If the same defective hardware or software is fitted to multiple models, a single technical issue could potentially affect vehicles wearing different badges.

That possibility is worth understanding, but it should not be confused with evidence of an existing fault.

Previous Volkswagen recalls show that electronic problems can have important consequences, yet they do not establish that these new models are unreliable.

Ultimately, the most important factor will not be how many components the four cars share, but how well those components perform in real-world use over time.
