Taking weight out of a modern car can be tricky: Crash regulations have necessitated heavier structures, emissions laws have forced additional complexity into vehicles, and amenities have added dozens of electronic control units and untold miles of cable. Many automakers, however, are now experimenting with shedding pounds as a means to maintain performance despite the current trend toward engine downsizing. To illustrate the potential of this approach, Audi engineers set out to create an A5 2.0T that weighs 500 pounds less than a 3400-pound Euro-spec A5 V-6 model (U.S. versions weigh roughly 200 to 300 pounds more due to options and higher levels of standard equipment). The result is an A5 coupe that, according to Audi, tips the scales at a svelte 2888 pounds despite retaining the 2.0-liter’s heavy iron block.

Audi let us compare a stock A5 3.2 FSI, equipped with the 265-hp V-6, against the lightweight concept with the 2.0-liter engine dialed back from 258 pound-feet of torque to deliver the same 243 as the V-6. We can attest to the fact that a 500-plus-pound reduction makes for a stunning dynamic improvement. Turn-in becomes more agile, the car can be tossed around with ease, and the 211-hp engine feels far stronger than its numbers suggest.

A regular A5 3.2 FSI seems downright clumsy in comparison. Audi claims the lightweight concept is 0.3 second quicker to 60 mph than the V-6. In our testing, the A5 V-6 ran from zero to 60 mph in 5.8 seconds, so we expect the lightweight concept to hit 60 mph in 5.5 seconds, a 0.7-second improvement over a standard A5 2.0T.

Audi originally intended the concept to emulate the performance of the V-8–powered, 354-hp S5, but, despite the weight loss, the concept still can’t match the S5’s acceleration. We understand that a second concept is currently being built—and we wouldn’t be surprised if this one was equipped with the 265-hp, 2.0-liter turbo four from the TTS. With that much power, the four-cylinder lightweight just might be able to trounce the S5’s V-8.

Most “efficiency” concepts make us dread the future; this one gives us hope.

To fill the gap in the 3-series lineup between the 300-hp 335i and 414-hp M3, BMW is introducing the 2011 335is coupe and convertible. We were unaware that said gap needed to be filled, but we’re told that the 335i is seen in the U.S. as just an ordinary 3-series, and as such, there’s room for something more exotic than a 335i but less outlandish than an M3. Now that we’ve been given the chance to drive the 335is coupe, we’re coming around to accepting this whole gap idea.

More Power and a Body Kit and . . .

Conceptually similar to the 330i Performance package model that was available as part of the previous-generation 3-series lineup, the 335is doesn’t go so far as to threaten the M3’s supremacy, but it definitely ups the sportiness quotient. To that end, the 335is gets 320 hp and 332 lb-ft torque from the twin-turbo 3.0-liter inline-six engine, and an overboost function allows for seven-second blasts of 370 lb-ft of torque. Unlike the regular-grade 2011 335i, the 335is sticks with the older twin-turbo engine for the simple reason that BMW engineers had more experience tuning it. This same engine can also be found in the Z4 sDrive35is that was introduced at this month’s Detroit auto show. In the Z4, the engine makes 335 hp; a more restrictive intake on the 3-series accounts for the 15-hp difference.

To make the 335is a track-worthy vehicle, BMW upgrades the cooling system with an additional radiator and beefs up the engine mounts. Inside are standard sport seats, steel pedals, an M Sport steering wheel, and textured aluminum trim. Between the seats sits the familiar six-speed manual, but it’s modified here to have shorter throws. For those who prefer not to shift for themselves, BMW is offering its seven-speed dual-clutch gearbox. The DCT system is identical to the one in the M3 and comes with steering-wheel-mounted paddle-type shifters.

Exterior styling builds on that of the 3-series’ 2011 freshening and adds an aggressive M Sport body kit. The kit has a more aggressive front fascia that ditches the coupe’s fog lamps in the interest of increased cooling capacity; the 335is convertible keeps its fog lamps. (And just to confuse you, we posted photos of preproduction coupes with fog lights; the decision to ditch them apparently came after these cars were built.) A new rear bumper incorporates a diffuser-style piece, and the twin exhaust pipes are finished in matte black. New gray-painted, split-five-spoke wheels are the only change to the chassis, despite the extra power—there are no tweaks or modifications to the suspension or brakes.

Same Poise, Even Better Soundtrack

Immediately on starting the engine, one detects a more noticeable hum from the new exhaust system. Less-restrictive mufflers snarl menacingly and only get angrier once the throttle is matted and the revs rise. As we’ve seen with other applications of the twin-turbo six, power is delivered with the immediacy of a large-displacement, naturally aspirated engine. The extra horsepower bestowed on the 335is isn’t exactly massive, but the car will still quickly shrink a straightaway, and it rockets into triple-digit speeds as if towed by a Boeing 747. Indeed, a few laps around Portugal’s Estoril racetrack revealed this car to be exactly what’s suggested by the spec sheet: a powerful 3-series with a fantastic soundtrack. As one might expect from the carry-over chassis, the balance, the predictability, and the unflappable poise that make the 3-series one of our favorite cars are all there in spades.

The 335is doesn’t exactly threaten the M3 performance-wise, and with a starting price of $50,525, the 335is coupe costs $8750 less than an M3 coupe. But compared with the M3 sedan, the 335is coupe saves only $5750; faced with that choice, we’d pony up for the four-door M3. Convertible versions of the 335is start at $59,075, or $8850 less than the M3 convertible. The 335is convertible will arrive in April; coupe buyers will have to wait until June. And don’t go looking for the 335is at dealerships outside North America; for once, BMW is building something just for us.

New sports coupes arrive like summer lightning and depart like uneaten guacamole: ignored, slowly fading to brown, awaiting the inevitable flush. The six-year-old Mazda RX-8 languishes through 2008 with sales the Hubble telescope wouldn’t register: just 2591 units through the end of August.

Mazda isn’t giving up, however. The Hiroshima headquarters considers rotary engines integral to its identity, so the RX-8 stays, a place keeper for a future all-new rotary engine currently code-named “16X” and due perhaps by 2012.

Meanwhile, the RX-8 gets a little stir to keep it green. Most obvious is the new front bumper that flares the grille and brake-duct openings for a more dangerous, grinning-cobra menace. Four glassy robot eyes now fill the taillight teardrops, the exhaust tips are bigger, and fresh wheel designs adorn the various trim levels.

Underneath, Mazda adds chassis stiffeners to further tighten an already athletic platform, and tweaked rear-suspension geometry settles the back end and helps sharpen steering response. The prop shaft also has been strengthened to reduce driveline vibration and noise.

Also new for ’09 is the R3. At $32,600, the RX-8 R3 is priced just $930 above the luxury Grand Touring and trades a few of the GT’s comfort bits—heated mirrors, automatic climate control, power seats—for go-fast bits such as 19-inch forged aluminum wheels, Bilstein shocks, and Recaro-brand leather-trimmed buckets. A spoiler, side-sill extensions, fog lights, and an even angrier front bumper also ride along, as does a 300-watt Bose stereo.

Steering that answers to palm twitches remains the RX-8’s best selling point, the R3 cruising flat and neutral through the wiggles without tire squeal or shimmy. Call us surprised that our skidpad runs were lower, generating 0.87 g to our previous 0.92. Brake performance stays about even, and the R3 impresses as every bit the joy toy its predecessors were.

The six-speed-only R3 runs on the same 232 horsepower and 159 pound-feet of torque as other RX-8 manuals (autos have 212 horses) but has foam-filled front crossmembers linking the front-suspension pickups for better sound-and-vibration damping. At 3060 pounds, the R3’s curb weight exactly matches that of our last RX-8 test car [“Four of a Kind,” June 2007].

The low-torque RX-8 was always tricky to get rolling without a stall. A shorter rear-end ratio in all 2009s—4.78:1 versus 4.44—means less revving and clutch slip in everyday driving. However, the second-to-third shift is now perilously close to 60 mph, which likely slowed the acceleration runs (6.7 seconds to 60 mph versus 6.5). Fuel economy isn’t helped or, apparently, hurt. We averaged 15 mpg, same as before.

Sporty cars come and eventually go, but for now, Mazda’s entertaining eccentric is signing up for another rotation.

The bulk of the Mazda lineup has recently been updated, and the Japanese carmaker will bring its Mazda 5 small minivan in line when it unveils the new 2011 model at the Geneva auto show in early March.

The update represents the model’s first major freshening in a while, and the first since going on sale in the U.S. in 2005. The 5, which is known as the Premacy in Japan, takes on styling cues from the Mazda 3 on which it’s based, in particular the smiley-face grille and pronounced fenders. Moving aft of the A-pillars, Mazda says the new 5 is the first production model to fully adopt the wind-blown, swooping styling language the company has refined on several stunning concepts, starting with the Nagare in 2006 and including the Furai racer from 2008.

Inspired by the beauty of flowing elements in nature—nagare means “flow” in Japanese—the design language is most evident along the sides of the 5, where swooping creases between the beltline and rockers appear to be sculpted by the wind, lending a sense of motion. These particular elements can be found in all the previous concept vehicles and, according to Mazda, help the 5 achieve improved aerodynamic efficiency with less drag and more optimal lift characteristics. The result definitely is striking—think BMW’s flame surfacing on magic mushrooms. A more-sculpted rear fascia with revised taillights rounds out the major tweaks to the body.

We have yet to learn the extent of the interior changes, but the layout will remain a spacious and flexible place for six, complete with dual sliding doors for easy entry and exit. Improved materials and revised equipment are expected in order to keep the 5 on par with the updated-for-2010 CX-7 and CX-9.

The 2011 Mazda 5 will go on sale in Europe in the fall of this year with several powertrains, the most notable of which is a new, direct-injected 2.0-liter inline-four with the company’s “i-stop” stop/start technology. When equipped with a six-speed manual transmission, the new 5 is said to reduce carbon-dioxide emissions, which are directly tied to fuel consumption, by 15 percent. A 1.8-liter four and a small-displacement turbo-diesel also will be available.

The current U.S.-market 5 sports a 153-hp, 2.3-liter four mated to either a five-speed manual or five-speed automatic gearbox. While we don’t expect performance to match that of, say, our Mazdaspeed 5 Boss Wagon, the fitment of the redesigned-for-2009 Mazda 3’s optional 2.5-liter mill, which makes 167 hp and is paired with either a six-speed manual or a five-speed auto, seems likely. As is par for the course these days, expect a slight bump in fuel economy over the current car’s city/highway ratings of 22/28 mpg with the manual and 21/27 with the automatic.

The big reveal of the refreshed 2011 Ford Edge will take place in about two weeks at the 2010 Chicago auto show, but why wait—these spy snaps give us a pretty clear idea of what form it will take. Not only that, but this prototype also previews the Sport trim, which should continue to be the sharpest-looking Edge in the drawer.

As with its twin, the Lincoln MKX, the angular Edge undergoes a dramatic mid-cycle revamp for 2011, starting with fresh front-end styling that actually has some radius edges. Indeed, shades of the Toyota Venza and the Honda Accord Crosstour—both prime competitors—can be seen in the Edge’s visage, with a vast majority of its frontal area devoted to the T-shaped arrangement of the headlamps and thick three-bar grille. It does not appear, however, that the new fascia will be affixed to new front fenders (the MKX, by comparison, is all-new from the A-pillars forward), but certainty on that point is complicated by this prototype’s black-and-white “cheese-puff” camouflage.

Other aesthetic changes for the standard Edge are expected to be minimal, although this Sport prototype wears flashier rocker panels and a diffuser-look rear bumper as conspicuous conceits to its Sport designation. And speaking of conspicuous, the 22-inch wheels seen here are kinda, sorta bitchin’, especially for a stock-out-of-the-box Ford family car. Rounding out the appearance changes are the new taillamps, which will feature LED elements.

Count On a Vastly Improved Interior

What we can’t see here is the new tech-laden cabin, although Ford itself released images of the interior a few weeks ago when it announced an innovative new connectivity suite called MyFord and MyFord Touch. (The systems include things such as in-car WiFi, improved Sync voice control, apps, and iTunes audio tagging; it all sounds pretty cool.) As such, we already know that the interior of the 2011 Edge will feature upgraded materials and capacitive touch controls in place of some conventional buttons and switches.

While the Edge and Edge Sport currently share one engine—a 265-hp, 3.5-liter V-6—the 2011 Edge could follow the MKX in offering FoMoCo’s 305-hp, 3.7-liter V-6, possibly as an upgrade exclusive to the Sport model. Of course, switching the entire lineup to the 3.7-liter mill is entirely possible, too. However the V-6 situation pans out, it’s relatively certain that the Edge will eventually be available with an EcoBoost turbocharged engine. It’s more likely to be the highly anticipated new 2.0-liter turbo four-cylinder rather than something burlier like the 355-hp, twin-turbo V-6 seen in the Taurus SHO and Flex EcoBoost. Ford has said that the 2.0-liter will be good for at least 230 hp.

Look for the 2011 Ford Edge to appear in showrooms late this summer. Of course, if you’re willing to brave some brutal cold and head to the 2010 Chicago auto show next month, you can see it long before then. Even better: Stay warm and point your browser right back here in just a couple of weeks to read full product information and see our photos from the show floor.
