Suvel peaks müüki jõudma siis selline masin nagu Opel GT(USA turul juba Saturn Sky Red Line ja Pontiac Solstice GXP nime alla saadaval). Üle pika aja seeriatootmises suht ligilähedane masin S14 Nissanile :) Hind peaks jääma ca 450.000 EEK kanti.

Tootja reklaamib autot ise nii:

Standard torque-sensing limited-slip differential
Performance-tuned suspension
Near 50/50 weight distribution for balanced handling
Four-wheel independent short/long arm suspension for optimal handling and stability
Coil-over Bilstein monotube shocks for excellent wheel control and road isolation
Four-wheel disc brakes with ABS for excellent stopping performance (18 velg on standardis, seega tehase pidurid peaksid päris suured olema)
Structural tunnel design and hydroformed longitudinal frame rails for a stiff body that results in greater vehicle responsiveness and better overall feel

Turbocharged intercooled 2.0-liter engine, direct injection. It produces 264 horsepower at 5300 rpm and 353Nm of torque at 2500 rpm. 0-100km/h 5.7 sec.

Highlights of the Ecotec 2.0-liter Turbo engine include:

Forged crankshaft
Forged connecting rods
Cast aluminum oil-galley pistons
Jet-spray piston cooling
9.2:1 compression ratio
Aluminum cylinder head with sodium-filled exhaust valves
High-pressure engine-driven fuel pump
Variable pressure fuel rail
Dual-scroll turbocharger
Components including the crankshaft, forged connecting rods and cast aluminum pistons are high-strength items that enhance durability. Jet-spray oil cooling directed toward an oil-galley piston help reduce piston temperatures. The system delivers pressurized oil to continuously lubricate and cool the pistons, which reduces friction and noise and ensures durability for the engine’s higher power levels. To enhance combustion, the piston tops feature a dish shape that deflects injected fuel toward the spark plugs.

To accommodate the direct injection system, the Ecotec 2.0-liter Turbo has a unique cylinder head and intake manifold. The cylinder head incorporates mounting locations for the fuel injectors – which are typically mounted in the intake ports or intake manifold on port injection engines. A high-pressure fuel pump delivers fuel to a variable-pressure fuel rail. Fuel enters the combustion chamber through precision multi-hole fuel injectors. The fuel pump, fuel rail pressure, fuel injection timing and injection duration are controlled by the engine control module. In this way, fuel is metered and delivered in a finely atomized spray.

Apart from the mounting positions of the fuel injectors, the cylinder head has conventional port and combustion chamber designs, although both are optimized for direct injection and high boost pressures. The sodium-filled exhaust valves and stainless steel exhaust manifold are durable components designed to stand up to the high-performance capability of the engine.

Opel’s second-generation, reinforced aluminum engine block is used in the GT; in particular, the main crankshaft bearing supports and cylinder walls have been strengthened. The high-performance engine’s high thermal load capacity facilitates the piston end’s oil-spray cooling and backs up the cylinders’ wet liner, which extends far downwards. The cast aluminum pistons transfer power via forged piston rods to the forged crankshaft.

The engine block also features two counter-rotating balance shafts, a low-maintenance chain drive for the camshafts and a cast-on oil filter housing, which is easily accessible from above.

Maximum turbo pressure is 1.38 bar.

Tühimass on ca 1350kg. Kõik arvustused kirjutavad, et masin näeb irl ülistiilne välja :)

Kindlasti on varsti saadaval ka korralikud chipid mis tõstavad numbrid ca 300hj-ni ja 450Nm-i. Päris lõbus masin tõotab tulla.

Autoleht kirjutas, et Eestis hind hakkab olema ca 480.000.-. S2000 maksab alates 635.000.-. Ei ole vist raske valida :)

On olnud võimalus selle autoga sõita. Liigub hästi, kuid mingi üliraju asi ta pole. Peainseneriga rääkides selgus, et neil polnud eesmärgiks üliraju sportauto, vaid kruiser. Välimus on muidugi kompu. Kaubanduskeskuse parklas seistes oli lausa publik ümber.

Soltice reviewdes väga vaimustusega ei olda (väga viga ka ei ole). Pigem Opel Speedster, tühikaal ~900kg ja sama mootor.

Speedsteri tootmine on vist juba mõnda aega lõppenud? Muidu jah, GT puhul saad Opeli nahas ülekaalulise Pontiaci, Speedsteri puhul tuunitud Lotus Elise :)

Speedster ei ole eriti auto nime väärt :) Mina sinna sisse ei mahu, salongi põhi on plekist, auto on imeväike - näeb välja ja sõidab nagu kart. Rinkale küll sobiv aga suvel igapäevaautoks pole parim variant.
