Renault's investment in Dacia continues to pay off in the showroom and on the balance sheet. The low-frills brand set new sales records worldwide, in Europe and in France last year, which is why the Romania-based carmaker will not be "reinventing the wheel," commercial director Francois Mariotte told Automotive News Europe. That means Dacia plans to keep making upgrades to its lineup without boosting prices for its refreshed models.
