  • chevy corvette zr1 motorauthority 042

    In an age known for its electric vehicles, hybrid drivetrains, clean diesels and alternative fuels, you might not think there's a place in the world for a pushrod V8 with architecture dating back to the 1950s. GM disagrees though, and is currently making a case for continuing the lineage of one of the world's great engines. GM is soon investing $400 million at its plant in Tonawanda, NY and $235 million at the St. Catherines plant for small-block production. As die-hard Chevy fans will tell you, the small block has plenty of plus points. It's reliable, strong, and offers great low-down torque...

    Volkswagen Debuts Cylinder Shut-Off Tech In 4-Cyl Engines

    Cylinder deactivation has been with us for several years in big V8 engines. Both GM and Chrysler have used it and Audi now offers it on its S range. Rather firing on all cylinders during steady freeway driving, the units use cylinder deactivation to save fuel when the power demand is low, shutting...

    Ford puts four-cylinder EcoBoost, Powershift plans on the table: 230hp, 2.0L

    Call it EcoBoost, call it TwinForce, it's a welcome addition to the Ford lineup for many buyers, packing more power in a smaller, more efficient engine. And soon the V6 version that debuted the twin-turbo technology will be joined by a four-cylinder, 2.0L 230hp version. That's the latest word from...

  • BMW 1-series
    BMW engineer confirms four-cylinders under consideration for U.S.

    About a year ago we brought you a report that BMW was looking at a four-cylinder 3-series for American sale, but that was at the height of the fuel-price crisis, and since then talk of the efficient BMW four-bangers has died down. A recent report has breathed new life into the idea, however, and...

  • 2009 volkswagen bluesport roadster concept 007
    Production Volkswagen Bluesport roadster still a possibility?

    When it first appeared in Detroit back in January the Bluesport concept stirred talk of the revival of the roadster segment, and especially the Porsche 914 and 356. Unfortunately, the Porsche's rebirth was ruled out last month, and this had led to fears that the same fate may ensue for a planned...

  • 2010 Buick LaCrosse

    The new 2010 Buick Lacrosse has made waves with its attractive design and overall build quality since its unveiling at the Detroit Auto Show in January. Soon after that General Motors increased the appeal of the car by announcing that it will be available with not only a 3.0L and 3.6L V6, but also a new Ecotec 2.4L direct-injection four-cylinder. According to a new report, a hybrid model is also expected in the near future. Speaking with Ward’s Auto, GM's global vehicle line executive James Frederico appeared to confirm the hybrid LaCrosse but did not disclose exact timing. "We are...

    Lotus offers new ‘Purist Edition’ Elise for U.S.

    Finding ways to lure customers into dealerships - and once there, secure the sale - has rarely been harder for car companies. And that's why we see so many schemes afoot to do just that. Lotus is taking a tried and true approach to the situation, however, offering lots of features for less money...

    Nissan reviewing U.S. diesel plans

    Diesel engine sales have stagnated in the U.S. due largely to lingering perceptions of the clattering, foul smelling contraptions of the 1970s and earlier. It hasn’t helped that many carmakers have been reluctant to even offer them because of the relatively high cost of emissions...

    Genesis Coupe 2.0T dyno test hints at 225hp+ true output

    Hyundai's new turbocharged 2.0L Genesis Coupe has had import tuner fanboys foaming at mouth, and their more resevered cohorts awaiting with interest, for months now. As the car begins to make the press rounds, it's starting to look like it may have more under the hood than the 210hp promised by...

    Volvo adds pair of new five-cylinder turbodiesels to engine lineup

    Diesel is the way of the present in Europe, and to hear some tell it, it's the future for the U.S. as well. Either way, Volvo will be prepared with two new diesels announced in detail today. The D5 five-cylinder diesel was announced for the S80 sedan back in January, but now full details on both...

  • 2010 ford fusion sport 004

    So smaller engines get better fuel economy - big surprise, right? Ford has recently been making a lot of noises about a transition to smaller engines based around their EcoBoost twin-turbo technology, but today the company is saying they'll be going four-pot in every car and crossover they offer by 2013. Turning big power out of a little engine courtesy of turbochargers is nothing new, but doing it in cars that have traditionally had V6s or V8s under the hood is, for American carmakers anyway. Plans for the four-cylinder EcoBoost Fusion were just released late last year. Ford is jumping in...

    New IndyCar engine plans stirring global interest despite delay to 2012

    Tough times and cutbacks, or even outright cancellation of programs, are mode throughout today's motorsports programs, and while the Indy Racing League (IRL) has announced it will delay application of its new engine package until 2012, the proposed format is already drawing interest from diverse...

  • 2009 Nissan Maxima
    New Renault-Nissan V6 diesel to power wide range of cars, SUVs

    Diesel engine sales have stagnated in the U.S. because of lingering perceptions of the clattering, foul-smelling contraptions of the 1970s and earlier. Many carmakers have been reluctant to even offer them in America because of the cost of emissions certification and small profit margins, but...

    GM releases LNF Turbo Upgrade Kit for Solstice, Sky, HHR

    The 2.0L turbo engine internally known as the LNF has been one of GM's unsung heroes over the past several years. Lying at the heart of the Pontiac Solstice GXP, Saturn Sky Redline and HHR SS, the engine generates a very respectable 260hp and 260lb-ft of torque in factory trim. But GM's performance...

    Four-cylinder Toyota Highlander pricing starts at $25,705

    Shifting demand for smaller and more fuel-efficient vehicles around the globe, but especially in North America, has hit carmakers hard.

  • 2009 Pontiac G6 GT
    Pontiac to offer four-cylinder G6 Coupe for mid-cycle update

    A mid-year refresh brings a smaller, more efficient 2.4L four-cylinder engine to Pontiac's G6 Coupe despite tumbling gas prices. Car sales have tumbled even further, however, and fuel prices are likely to rise, so the decision is surprising only in its lateness - the G6 Coupe had previously only...

  • 2011 Chevrolet Volt

    General Motors today announced that it will invest $370m for a new small engine manufacturing plant located in Flint, Michigan. The plant is an important step towards preparing GM to introduce the crucial Volt and Cruze products to the North American marketplace and attempt to gain leadership in terms of low-mpg vehicles. Two new four-cylinder engines will be produced at the plant – a 1.4L turbo for the Cruze and a 1.4L naturally aspirated mill for the Volt. The smaller engine sizes will help the vehicles reduce their overall miles-per-gallon rating while still delivering adequate power...

One of its strategies is to take its focus away from the U.S. and instead attempt to boost sales in more profitable markets. The plan comes from BMW's new...
