Next Mazdaspeed3 could go naturally aspirated?

The new Mazda3 is a stunner, both aesthetically and from a driving perspective. As with all good things, though, there's always room for improvement. That's where the wizards from Mazdaspeed come in. Mazda's in-house tuner has been tweaking and turbocharging the five-door Mazda3 since 2007, with impressive results.
We've shown you renderings of what the third-generation Mazdaspeed3 could look like, and for the most part your response was quite positive. Now, AutoExpress has come out with details of just what might be under that long hood. According to our friends across the pond, the new Mazda3 MPS (that's what the Speed3 is called in Her Majesty's auto industry) will be arriving with a new, high-revving, naturally aspirated engine. Wait, what?
Yes, if the rumors are to be believed, the next Mazdaspeed3 will ditch its turbocharger. According to an anonymous engineer, the new MS3 will arrive in December (this is for the UK market, mind you) with a 200-horsepower, naturally aspirated engine. The 2.0-liter mill is based on the Skyactiv engine in the new 3, and should be capable of a sub-seven-second run to 62 miles per hour.

Mazda considers expanding Takata recall nationwide

Vehicle recalls have come in force recently. Honda expanded its front driver's side Takata airbag inflator recall nationwide to cover an estimated 5.4-million vehicles, and the National Highway Traffic Safety Administration added 19 notices to its database covering safety campaigns dating back to October. It looks like there could be one more to add to the list soon because Mazda is considering a possible nationwide expansion of its own inflator repairs. A company spokesperson tells Reuters that there is no decision yet when to actually make this nationwide expansion of the driver's side inflator recall official, and the company isn't sure how many vehicles may be affected. Mazda just expanded the scope of its Takata inflator recalls to additional regions earlier in December. The move took its total number of units in need of repair from around 65,000 under the earlier NHTSA estimate to 86,773, according to the company. So far, the automaker's US campaign has included the 2003-2007 Mazda6, 2006-2007 MazdaSpeed6, 2004-2008 Mazda RX-8, 2004-2005 MPV and 2004 B-Series pickup.

Mazda6 diesel engine delayed over low performance, still coming

Oh Mazda... we had many hopes for the promised diesel four-cylinder in the Mazda6, but those have remained largely unfulfilled, as the oil-burning powerplant has failed to appear on dealer lots following its 2012 LA Auto Show announcement. Despite engineering issues that forced the company to announce that the program was delayed back in September 2013, Mazda remains adamant that the 2.2-liter Skyactiv-D is still coming to our shores. "We're still very much committed to diesel," Mazda's North American CEO, Jim O'Sullivan, told Automotive News. "We are still working on getting the performance aspects up to where we want them, and we do have a plan – an engineering road map – to get it done." According to AN, Mazda's initial plan with the 2.2-liter diesel was to build an engine so clean it could get by without an aftertreatment system, which generally accounts for the price premium of diesel engines versus their gas counterparts. The new system has come with performance issues, though, necessitating the delays. "If [we were] a commodity brand and didn't care about that, it would be on the market right now," O'Sullivan told AN. "But I know the people were expecting something from us, expecting certain drive characteristics and performance, and I didn't want to disappoint them." While O'Sullivan's defense of the diesel Mazda is admirable, the exec stops short of giving us an indication of when the new engine will finally arrive.
