Until now, it does look like Volkswagen's investment of $2.9 billion in Suzuki wasn't going to impair the deal, but a move such as looking for alternative sources for their growth in India is likely to happen. Suzuki, meanwhile, is sourcing Fiat diesel engines to their Hungarian cars. This duel between Volkswagen and Suzuki may look a bit silly, though results might be serious, so a proper solution as to working together or breaking the alliance must be worked out sooner rather than later.
