5. Conclusions and implications
Luxury brand extensions are always tempting for luxury companies and marketers because they can leverage their brand asset based on their strong brand image. Brand extension strategies can reduce the cost of introducing new products and increase the success rate through communication with loyal consumers. However, potential risks, such as failure of introducing the new brand, diluting the popular parent brand image, cannibalization of the original brand, and reducing the market share of the parent brand, exist. Thus, luxury companies should consider brand extension strategies as an opportunity, but also note the possible negative consequences. In this context, horizontal brand extension, which introduces the new products into a new category, may help to reduce the potential risks and expand their product spectrum. In this study, the positive effect of brand equity of the luxury automobile brand was found in brand extension into the rental car service category. Luxury brands are able to use horizontal brand extension strategies to promote a luxury experience to a wider consumer base in the service setting with minimum risk. In addition, since there is a difference between consumers’ demographic backgrounds, marketers should develop the extended service brand to meet the needs of the different consumer segments.
